Zalgiris

BC Žalgiris was formed in 1944. The team was named ASK from 1945 to 1947, after which it was named SKIF from 1947 to 1949. Beginning in 1950, the team was renamed Žalgiris. The team quickly rose to prominence, winning the Soviet Union's top-tier USSR Premier Basketball League twice, in 1947 and 1951, as well as multiple domestic Lithuanian championships. In the following years, the team won two silver medals in the USSR league in 1949 and 1952, and four bronze medals from 1953 to 1956. Žalgiris also won the USSR Basketball Cup in 1953. The team at the time was led by Stepas Butautas, Vytautas Kulakauskas, Justinas Lagunavičius, Kazimieras Petkevičius, and later, by Stasys Stonkus and Algirdas Lauritėnas. In the 1960s, the team's play declined, and many new young players joined the team, such as Modestas Paulauskas, Romualdas Venzbergas, Henrikas Giedraitis, Algirdas Linkevičius and Sergejus Jovaiša.

Žalgiris became the dominant club in the Soviet Union and Europe when they added Valdemaras Chomičius and Rimas Kurtinaitis to their roster, along with coach Vladas Garastas. The team won bronze medals in the Soviet Union championship in 1971, 1973, and 1978. In 1980, Žalgiris debuted in the 1980–81 FIBA European Cup Winners' Cup. Their biggest addition, though, was 17-year-old Arvydas Sabonis, who debuted with the club in 1981 at 209 centimetres (82 in) and grew another 12 centimetres (4.7 in) in the next couple years. Sabonis soon became known for his versatility, being able to play defense, assist his teammates, shoot three-pointers, and dominate inside the paint.

From 1985 to 1987, Žalgiris won three consecutive Soviet Union National League championships, beating CSKA Moscow (English: Central Sports Club of Army) in the finals in all three years. In 1985, they reached the Saporta Cup final, but lost to FC Barcelona. Despite the loss, Žalgiris participated in EuroLeague the next year as the Soviet Union champions, reaching the finals and losing to rival KK Cibona. Žalgiris was emerging as one of the top clubs in Europe at the time.

In the mid-1980s, the rivalry between Žalgiris Kaunas and CSKA Moscow served as a major inspiration for the Lithuanian national revival, especially when they played in Kaunas Sports Hall. It contributed to the emergence of the Sąjūdis national movement and the re-establishment of state independence. In 1987, however, Žalgiris suffered a setback when star player Sabonis suffered a torn achilles tendon. Three months later, he tore it again, causing him to miss most of the 1987–88 season. That season, Žalgiris won a silver medal, losing to CSKA Moscow in the Soviet League finals. The next season, Žalgiris managed to reach the European Cup Winners' Cup semi-finals and won a silver medal in the Soviet league, losing a dramatic finals to Stroitel Kiev.

Just before the start of the 1989–90 season, Žalgiris lost Sabonis, Kurtinaitis, Jovaiša, Chomičius, and head coach Garastas, as the Iron Curtain, which had barred Lithuanian basketball talent from becoming internationally sought-after, had been lifted. In the 1989–90 season, Žalgiris reached the Clubs Cup Winners' Cup semi-finals, where they lost to Real Madrid.

After the Act of the Re-Establishment of the State of Lithuania, Žalgiris left the USSR championship. Over the next few seasons, Žalgiris won Lithuanian championships in 1991, 1992, and 1993, and the LKF Cup in 1990. They won their first LKL title in 1994, beating Atletas Kaunas 3–1 in a four-game series. Over the following two years, Žalgiris again dominated LKL tournaments, beating Atletas Kaunas 3–0 in 1995 and 3–2 (after being down 0–2 in the series) in 1996, and had success participating in the 1995–96 FIBA European Cup when Rimas Kurtinaitis returned to play for his home team. In 1997, Žalgiris again won the LKL championship, beating Žemaitijos Olimpas 3–0 in the finals, and reaching round 16 in the Saporta Cup, losing to Paris Basket Racing. Players such as Darius Lukminas, Gintaras Einikis, Kęstutis Šeštokas, Dainius Adomaitis, and Darius Maskoliūnas played for the club during this period, coached by Jonas Kazlauskas.

Žalgiris enjoyed its greatest success as a club during the 1997–98 and 1998–99 seasons. They were coached by Jonas Kazlauskas with a new generation of Lithuanian talent, including Saulius Štombergas, Dainius Adomaitis, Eurelijus Žukauskas, Tomas Masiulis, and Mindaugas Žukauskas, and experienced foreign players Franjo Arapović and Ennis Whatley. The team defeated Stefanel Milano 82–67 in the 1998 FIBA Saporta Cup final in Belgrade. Saulius Štombergas scored 35 points in the final. Žalgiris also won a fifth-consecutive LKL title, this time against Atletas Kaunas.

In the 1998–99 season, Žalgiris made it to the EuroLeague Final Four for the first time in the club's history, and were crowned champions after defeating Olympiacos and Kinder Bologna in the semi-final and the final, respectively. Tyus Edney was named EuroLeague Final Four MVP. Žalgiris also won LKL and North European Basketball League (NEBL) titles that season.

The year after winning the EuroLeague, Žalgiris suffered one of its worst seasons. The club was eliminated after the group stage in the EuroLeague, finishing third in the NEBL and losing the LKL finals to Lietuvos Rytas for the first time. In the 2000–01 season, the team reached the new EuroLeague playoffs, but lost to AEK. Žalgiris won the LKL championship, beating Lietuvos Rytas 3–2. The 2001–02 season was again disappointing, as the team was eliminated in the EuroLeague after the group stage and lost the LKL championship. In the 2002–03 season, they were again eliminated in the EuroLeague playoffs, but achieved the LKL championship, beating Lietuvos Rytas 4–2.

Sabonis became the principal owner of the club in 2003, after playing for many years in the Spanish ACB League and the North American National Basketball Association (NBA). He also played for the club during the 2003–04 season, winning EuroLeague Regular Season and Top 16 MVP. Žalgiris almost made it to the EuroLeague Final Four, but were stopped by Maccabi Tel Aviv, who tied the game with Derrick Sharp's last-second three-pointer at the end of regulation and went on to beat Žalgiris in overtime. The season ended on a high note, as Žalgiris swept Lietuvos Rytas 4–0 in the LKL championship.

After the departure of Sabonis at the conclusion of the 2003–04 season, Žalgiris faced a series of ups and downs. In the 2004–05 season, mainstays Tanoka Beard, Mindaugas Timinskas, Dainius Šalenga, and new addition Robert Pack enabled Žalgiris to have a respectable season. In the EuroLeague, Žalgiris finished the regular season with an 8–6 record, including wins on the road against heavy favorites Maccabi Tel Aviv and FC Barcelona. However, in the Top 16 phase, the team entered a long slump and finished with an 0–6 record. Žalgiris recovered on the domestic front, easily defeating ULEB Cup winner Lietuvos Rytas in the LKL finals with a 4–0 sweep, and also won the inaugural Baltic Basketball League (BBL) championship, beating Lietuvos Rytas in the finals 64–60.

In the 2005–06 season, the team suffered many changes. Mindaugas Timinskas, Dainius Šalenga, and Robert Pack all departed the team, so Žalgiris built a younger team while signing Ed Cota to return. With the emergence of Darjuš Lavrinovič, Žalgiris started the season solidly, finishing the EuroLeague regular season with a 9–5 record. Off-court, Žalgiris had many issues, resulting in a huge slump for the team. They ended the top-16 phase with another 0–6 record and lost both the LKL and BBL titles to Lietuvos Rytas. The lone bright spot became the play of emerging point guard Mantas Kalnietis, who was signed both as a replacement for the released Cota and due to very poor play from new point guard and longtime NBA player Kenny Anderson.

Žalgiris had a new coach for the 2006–07 season, Ainars Bagatskis, but suffered a terrible EuroLeague regular season. After Ainars Bagatskis was replaced by assistant coach Rimantas Grigas and the signing of new point guard DeJuan Collins, Žalgiris won the newly established LKF Cup by beating Lietuvos Rytas. Žalgiris also beat Lietuvos Rytas in the LKL finals.

Before the 2007–08 season, Žalgiris signed longtime EuroLeague player Marcus Brown. Žalgiris also played against NBA teams for the first time. The team had a successful regular season in the EuroLeague, finishing with an 8–6 record, but suffered another disappointment in the top 16, finishing with a 1–5 record. Žalgiris also won the LKF Cup for the second consecutive year, beating Lietuvos Rytas 83–72 in the finals.^[] In the BBL finals, Žalgiris defeated Lietuvos Rytas 86–84 in the finals on a last-second shot by Collins. Žalgiris retained the LKL title, beating Lietuvos Rytas 4–1 in the LKL finals in which Brown was named MVP.

The 2008–09 season started on a very high note, with contract extensions for Jonas Mačiulis and Loren Woods, retaining leader Marcus Brown, and the signing of new point guard Willie Deane, who replaced the departed DeJuan Collins. However, financial difficulties lead to poor play from the team and the firing of coach Grigas, who was replaced by longtime player and assistant coach Gintaras Krapikas. Willie Deane was soon released, in large part due to his poor performance in the EuroLeague, which led to a seven-game losing streak. The team recovered under point guard Mantas Kalnietis, and finished the EuroLeague regular season with a 2–8 record, missing the top 16. Despite growing financial difficulties, and the departure of Loren Woods, the team made the LKL and BBL finals, as well as the LKF Cup finals. Despite this, this was the most Žalgiris could accomplish, as they lost to Lietuvos Rytas. Jonas Mačiulis, who became the team leader during the season, left after the season ended.

During the 2008–09 season, Žalgiris faced significant financial difficulties. In 2009, Sabonis sold most of his stake to the local Ūkio banko investment group (ŪBIG), headed by Vladimir Romanov, who ended up controlling a 75% stake in the club. Sabonis retained 21.5% ownership of the club, 3% was owned by a minority group, and 0.5% was owned by the Kaunas municipality.

In the 2009–10 season, Romanov became unpopular among Žalgiris fans. After the departures of Jonas Mačiulis and Paulius Jankūnas, the team extended the contract of Marcus Brown and also signed Martynas Pocius, who quickly became one of the best players on the team. The team also re-signed point guard Mantas Kalnietis, who turned down an offer from Benetton Treviso. The team started the season by winning the new BBL Cup against Lietuvos Rytas. However, subsequent poor performances led to head coach Krapikas being replaced by former Lithuanian national team coach Ramūnas Butautas, who led the team to the EuroLeague Top-16 phase with a 3–7 regular season record. After the team entered a slump, Romanov controversially fired Butautas, replacing him with assistant coach and former captain Darius Maskoliūnas. Under Maskoliūnas, Žalgiris came its closest to the EuroLeague Top-8 phase, finishing with a 2–4 record. Žalgiris won back the BBL title by beating Lietuvos Rytas in the finals, but lost the LKL finals to Rytas by 4–3. Romanov fired coach Maskoliūnas during this series, leading to speculation that Romanov had intentionally lost the finals to allow Lietuvos Rytas to qualify for the EuroLeague season. The season is widely considered the most controversial in club history.

Before the 2010–11 season, Žalgiris re-signed Paulius Jankūnas and DeJuan Collins, signed Tomas Delininkaitis, and brought in Serbian coach Aleksandar Petrović as the new head coach. The season began with Žalgiris playing very strongly, but after a slump, Romanov fired Petrović. They qualified for the Top-16 phase only in the final games, with a 5–5 record. After a controversial departure from center Mirza Begić,^[] the slump continued under new coach Ilias Zouros, with a 1–5 record in the Top-16 phase. However, after the recovery of Marcus Brown (who was injured for most of the season), Žalgiris won back the LKF Cup from Lietuvos Rytas and defeated VEF Riga in the BBL finals. In the LKL finals, Žalgiris easily defeated Lietuvos Rytas 4–1, regaining the LKL title for the first time since 2008.^[]

Due to the NBA lockout that impacted the 2011–12 season, Žalgiris signed former Toronto Raptors wing Sonny Weems and former Denver Nuggets point guard Ty Lawson. The team also re-signed long time fan-favorite Marko Popović. and signed longtime Lietuvos Rytas player and former Lithuanian National team captain Robertas Javtokas as center. However, the season started very poorly for Žalgiris. Hoping to end the slump, Romanov fired coach Ilias Zouros and replaced him with former Lietuvos Rytas head coach Aleksandar Trifunović. Despite initial improvement, as the team finishing the EuroLeague regular season with a 4–6 record and a trip to the Top 16, the slump continued and the team's EuroLeague season ended quickly. After Ty Lawson left the team, Mantas Kalnietis became a true leader for Žalgiris and played his best season yet. The team slowly recovered, winning the LKF Cup. After being eliminated in the VTB playoffs, Žalgiris made the BBL Final Four, winning against Lietuvos Rytas in the finals despite losing leader Sonny Weems (who was released due to injury) and DeJuan Collins (who was released due to failing a drug test). With very solid play from Marko Popovič and Tomas Delininkaitis, Žalgiris retained the LKL title, defeating Lietuvos Rytas in the finals 4–1. The club had achieved a second consecutive "triple crown" of Lithuanian League, Lithuanian Cup, and Baltic Cup.

For the 2012–13 season, Žalgiris signed Lithuanian national team players Rimantas Kaukėnas, Darjuš Lavrinovič, and Kšyštof Lavrinovič; Unicaja Malaga star Tremmell Darden; and point guard Oliver Lafayette. The season began with Žalgiris winning the newly established LKF SuperCup against Lietuvos Rytas. Early in the season, Mantas Kalnietis left the team and was replaced by Ibrahim Jaaber. Under new coach Joan Plaza, Žalgiris had their best EuroLeague start with five consecutive wins. They finished at the top of their group for the first time in 13 years, with an 8–2 record. In their 76–66 home victory against CSKA Moscow, Žalgiris broke their attendance record, with 15,812 spectators. In January 2013, Jaaber departed from the team for personal reasons and was replaced by Donnie McGrath in February. In the coming months, financial troubles returned to the club, which led to the departure of Darden. The crisis coincided with the ongoing collapse of Ūkio Bankas. The bank's main shareholder Vladimir Romanov, who also owned the majority of shares of Žalgiris and was the club's president, abruptly left the country and flew to Russia in early March 2013, abandoning his stake in the club. On 20 March 2013, vice president Paulius Motiejūnas was named the team director. Despite the financial and management struggles, Žalgiris finished the Top-16 phase with a 6–8 record, the best in club history, but narrowly missed the playoffs. Žalgiris also won the group phase in the VTB United League. In May, Žalgiris won their third straight LKL title, sweeping Lietuvos Rytas 4–0 in the finals. After winning the LKL title, Žalgiris competed in the VTB United League playoffs, defeating Nizhny Novgorod in the quarterfinals but losing to Lokomotiv Kuban in the semi-finals. Despite the loss, Žalgiris was awarded the bronze medal for the first time since 2010.

After the loss of team owner Vladimir Romanov and the departure of head coach Joan Plaza, Žalgiris rehired Ilias Zouros as head coach for the 2013–14 season. Žalgiris left the VTB United League because of the changes in the EuroLeague format that meant that the teams who did not qualify for the Top 16 would have a chance to play in the EuroCup playoffs.

Žalgiris signed Justin Dentmon and Šarūnas Jasikevičius to one-year deals. After a poor start to the season, Zouros was fired as head coach and replaced by Saulius Štombergas. Žalgiris made the Top 16 for the fifth consecutive time (with a 5–5 record). However, Žalgiris began to struggle in the LKL. The Top 16 proved to be difficult, with Žalgiris losing many games by 5 points or less (a 2–12 record overall). After a few losses in the LKF Cup and the LKL, Štombergas resigned and was replaced by Gintaras Krapikas as interim head coach. In the last week of Top-16 play at home, Žalgiris beat Spanish champions Real Madrid. Justin Dentmon scored 36 points in that game, the most by a Žalgiris player in modern EuroLeague, and Dentmon also made 74 three-pointers during the season (a EuroLeague record since 2000).

After a loss to Lietuvos Rytas in the final LKL regular season game, Žalgiris entered the playoffs as the fourth seed, the worst in club history. They faced Lietuvos Rytas again in the semi-finals, the first time in 15 years that they did not meet in the final round. Žalgiris advanced to the finals against Neptūnas Klaipėda, taking the series 4–2 and winning their fourth consecutive LKL championship.

During the 2014–15 preseason, Žalgiris made significant changes to the squad, replacing Justin Dentmon with Maalik Wayns, who was in turn replaced by Will Cherry. Žalgiris also signed Darius Songaila from rival Lietuvos Rytas and James Anderson from the NBA. Šarūnas Jasikevičius retired and became an assistant coach, and more young players were brought to the team. Young point guard Lukas Lekavičius was the main bright spot as the team began LKL play. In the EuroLeague, a 5–5 record sent Žalgiris to the top 16 phase where the team finished with a 5–9 record. In February, Žalgiris won the LKF Cup for the first time in three years. Žalgiris finished the LKL regular season in dominating fashion, with 12 straight wins, and they defeated Lietuvos Rytas in the finals. This win was the club's fifth consecutive LKL title and their 17th overall.

Žalgiris had a total of seven players who competed in EuroBasket 2015. They finished the off-season by signing Ian Vougioukas at center. Žalgiris finished the 2015–16 EuroLeague regular season with a 5–5 record and qualified for the Top-16 phase for the seventh consecutive season. After a poor start to the Top 16, head coach Krapikas was replaced by Šarūnas Jasikevičius, but injuries to Javtokas and the departure of Kalnietis led the team to a huge slump and a loss to Lietuvos Rytas in the King Mindaugas Cup final. After strong criticism of the team management for not finding a center to replace Javtokas, Žalgiris signed new point guard Jerome Randle. While the EuroLeague season ended with a 2–12 record, a hugely disappointing result, the team later recovered by finishing in 1st place in the LKL regular season over King Mindaugas Cup winner Lietuvos Rytas. Žalgiris defeated Neptūnas Klaipėda in the LKL finals, winning their sixth consecutive LKL title with a 4–1 record.

In November 2015, the ongoing conflict between FIBA and Euroleague came to a head when FIBA announced the formation of the Basketball Champions League, and courted EuroLeague teams to join their new championship. However, EuroLeague's long-term-license teams, such as Žalgiris, decided to stay with the Euroleague Basketball Company.

Žalgiris's preparation for the 2016–17 season began during the 2016 LKL finals, when the club signed point guard Léo Westermann to replace the departing Jerome Randle. After the season, long-time Žalgiris players Siim-Sander Vene and Kaspars Vecvagars left the team, while Žalgiris chose to retain the services of Seibutis and Motum. Head coach Jasikevičius was pursued by FC Barcelona Lassa, but decided to remain with Žalgiris. To correct the previous season's lack of a good shooter, Žalgiris signed Kevin Pangos; the team was loaned Augusto Lima from Real Madrid to replace Vougioukas at center. Žalgiris also signed the returning Artūras Milaknis to a 3-year deal. German prospect Isaiah Hartenstein was scheduled to make his professional debut after being signed the previous season. In August, Žalgiris signed Antanas Kavaliauskas, the captain of Lietuvos Rytas who had previously promised to never play for Žalgiris; Kavaliauskas apologized to fans after the signing was announced.

In February, Žalgiris won their first title of the 2016–17 season, winning the King Mindaugas Cup by defeating Lietkabelis Panevėžys in the finals 84–63. Edgaras Ulanovas was named tournament MVP. In the EuroLeague, Žalgiris exceeded expectations with a 10th-place finish (14–16 record), getting a win against defending champion CSKA Moscow and finishing ahead of FC Barcelona Lassa and Maccabi Tel Aviv. Players Brock Motum, Léo Westermann, Edgaras Ulanovas, and Lukas Lekavičius developed strongly, and team captain Paulius Jankūnas played one of his best seasons of his career, leading the team in scoring and rebounding. In the LKL, Žalgiris won the regular season with only a few losses, sweeping their rival Lietuvos Rytas, with the toughest challenge coming from a powerful Lietkabelis squad that contained former Žalgiris players Darjuš and Kšyštof Lavrinovič. In the LKL playoffs, Žalgiris easily advanced to the finals, defeating Lietkabelis for their seventh straight LKL championship, 4–1.

Prior the 2017–18 season, Žalgiris reached an agreement with club sponsor Avia Solutions Group to guarantee private flights for the team during away games in a refurbished business-class Boeing 737. The off-season work began just a week after winning the LKL championship, when breakout player Brock Motum signed with Anadolu Efes S.K. To replace Motum, Žalgiris signed Aaron White, who had played a season with Zenit Saint Petersburg. Léo Westerman signed with CSKA Moscow, and was replaced by talented guard Vasilije Micić. To replace Seibutis, Žalgiris originally signed Royce O'Neale, who terminated his deal just weeks later to sign with the Utah Jazz. Žalgiris then signed Axel Toupane to replace him. Because center Robertas Javtokas announced retirement and the loan of Augusto Lima ended, Žalgiris signed Brandon Davies of AS Monaco Basket at the center position. The most-shocking departure came at the end of June, when breakout point guard Lukas Lekavičius signed a contract with Panathinaikos. Needing a new point guard, Žalgiris signed Dee Bost, also of AS Monaco. Coach Jasikevičius also re-signed with Žalgiris, and the retired Javtokas became the new sports director of the team. On September 22, Žalgiris played a game in London against Polski Cukier Toruń, which Žalgiris won 87–61. Žalgiris won the King Mindaugas Cup for the second consecutive year, defeating Lietuvos rytas 81–62 in the finals. Edgaras Ulanovas won the tournament MVP for the second straight year.

In the 2017–18 EuroLeague, Žalgiris was again projected to be one of the worst teams. Žalgiris struggled in the early season before putting together a five-game streak to finish the first round 10–5, tied for third place in the standings. In the second round, Dee Bost was replaced by Beno Udrih. Žalgiris struggled for the first few weeks of the second round, but fought its way to an 18–12 record (sixth place) and qualification for the EuroLeague playoffs for the first time since 2001. The team qualified for the 2018 EuroLeague Final Four after beating Olympiacos in game 4 to clinch a 3–1 series win. The team achieved this despite having the second-lowest budget in the league. Žalgiris lost to Fenerbahçe in the semifinals, 76–67. In the third-place game, Žalgiris faced longtime rivals CSKA Moscow; Žalgiris led by as much as 24 points, but CSKA's late-game rally made it so Žalgiris only narrowly won 79–77, achieving third place in the EuroLeague. In the LKL, Žalgiris won the regular season and beat Lietuvos Rytas in the finals with a 4–1 record, earning their eighth consecutive LKL championship. This was the club's best season since 1999.

After a near-perfect season, the off-season was difficult. Žalgiris lost its front court as Pangos went to FC Barcelona Lassa and Micič signed with Efes. Žalgiris signed Nate Wolters as the team's new point guard. After the departure of Beno Udrih, Žalgiris signed Donatas Sabeckis from Šiauliai, who lead the LKL in assists. Toupane left the team to sign with Olympiacos; to replace him, Žalgiris signed former-teammate Marius Grigonis, who was having a successful career abroad, to a multi-year deal. They also signed talented guard/forward Thomas Walkup. To replace reserve Martynas Sajus, Žalgiris signed Laurynas Birutis, who was loaned to and had a successful season with Šiauliai. Several more reserves, Paulius Valinskas and Gytis Masiulis, were loaned to other LKL teams so that they could gain more playing time. Ulanovas also signed a new contract. Like the previous season, the biggest concern was the future of coach Jasikevičius. Despite offers from other EuroLeague teams and the Toronto Raptors, Jasikevičius remained with Žalgiris, signing a new contract. Former player Tomas Masiulis replaced Darius Songaila in the coaching staff. In September, Žalgiris signed the returning Léo Westermann to fill the point guard spot.

In the 2018–19 LKL season, Žalgiris finished the regular season in first place, and swept the series finals against Rytas, winning the series 3–0, for a ninth consecutive LKL championship. However, Žalgiris struggled at the start of the 2018–19 EuroLeague season. Needing another point guard, Žalgiris signed Derrick Walton in October. By December, Žalgiris was in sixth place with a 7–7 record. However, injuries decimated the team. Walton's disappointing play led to decreasing playing time and a release in February 2019. Later in February, Žalgiris suffered a loss in the King Mindaugas Cup to Rytas Vilnius, losing the tournament for the first time since 2016. By the start of March, Žalgiris was 13th in the EuroLeague with a 9–15 record. The team's play started to improve when Walkup was pushed to the point guard position to replace Walton, Westermann returned after being injured, and improving play by Thompson led to a six-game winning streak. Their 15–15 record clinched the final spot in the playoffs. In the EuroLeague playoffs, Žalgiris lost to Fenerbahçe. Žalgiris broke the EuroLeague's home attendance record with an average of 14,808 spectators in the Žalgiris Arena.

During the off-season, many players (including Westermann and Thompson) announced their retirement. Lukas Lekavičius returned to the team after two seasons in Greece, and Alex Pérez was signed to replace Westermann. Jock Landale and Zach LeDay, of Olympiacos, were signed to complete the front court. Martinas Geben, who had signed a long-term deal the previous summer, earned a spot on the roster after a successful season with Juventus Utena in the LKL, where he was named Season MVP. Coach Jasikevičius remained with the team for one more season. Pérez, however, spent just a few months with Žalgiris, and was released in November due to his weak play. Žalgiris also signed shooting-guard K. C. Rivers in November.

Žalgiris won the King Mindaugas Cup by beating Rytas Vilnius 80–60 in the finals. Ulanovas was named the MVP of the tournament, his fourth MVP award in Lithuanian Cup competitions. Due to the COVID-19 outbreak, the 2019–20 LKL season was ended prematurely, and with Žalgiris firmly leading the standings, Žalgiris was announced as champions, their 10th consecutive LKL championship. In the 2019–20 EuroLeague, Žalgiris struggled for most of the season, including plummeting to the bottom of the standings, but recovered by February 2020. With the EuroLeague season stopped due to the COVID-19 outbreak, Žalgiris finished in ninth place.

With the season ending prematurely due to the COVID-19 situation, Žalgiris started their off-season work early. LeDay, Landale, Ulanovas, and Rivers all left the team during the summer, but the biggest departure was of coach Jasikevičius, who left Žalgiris (along with the rest of the coaching staff) and signed with FC Barcelona in July. On July 14, Žalgiris announced the signing of Martin Schiller as the team's new head coach. Schiller had previously worked with the Salt Lake City Stars of the NBA G League, and had been named the NBA G League Coach of the Year in 2020. Schiller brought in Arne Woltmann and Tautvydas Sabonis as his assistant coaches, with Evaldas Beržininkaitis being the only person remaining on the team from Jasikevičius's old staff. Žalgiris brought in a bevy of new players, but the most surprising signing happened in June when Žalgiris bought out Marek Blaževič, a talented prospect, out of rival squad Rytas Vilnius.

While the expectations for the upcoming season were not promising under Schiller, Žalgiris surprised everyone and stayed in the playoff hunt throughout the 2020–21 EuroLeague season. Despite eventually not making the playoffs, Žalgiris finished the EuroLeague season with a respectable 17–17 record. They won the King Mindaugas Cup and their 11th consecutive LKL final by beating Rytas 3–0.

In 2021, Žalgiris signed Tyler Cavanaugh, Niels Giffey, Mantas Kalnietis, Josh Nebo, Edgaras Ulanovas, Jānis Strēlnieks, and Emmanuel Mudiay. They also extended their contract with Lukas Lekavičius. Žalgiris lost all five LKL preseason games, playing seemingly worse each game. Žalgiris had a difficult start in the 2021 LKL regular season—while they won all three games, they struggled even against the weakest of teams. After a 0–2 start in the EuroLeague, Žalgiris fired coach Martin Schiller, replacing him with Jure Zdovc. Injuries to players such as Lauvergne and Strelnieks, struggles in the LKL, and disappointing play from projected leaders such as Mudiay resulted in the worst start ever (0–9) for Žalgiris in the Euroleague. In the LKL, a loss to BC Rytas resulted in Žalgiris falling out of first place.

Žalgiris released Mudiay in November, replacing him with point guard Tai Webster, and signed shooting guard Zoran Dragić. The moves backfired—Webster struggled even in the LKl, while Dragič rarely saw playing time and was released by the end of the year. New signees such as Regimantas Miniotas also saw limited playing time. Losses in the Euroleague resulted in Žalgiris attendance falling to record lows. By February, Žalgiris was in last place with a disastrous 4–20 record, but recovered by March 2022, including memorable wins over the Jasikevičius-lead FC Barcelona and Real Madrid, future participants of the Euroleague Final Four, in particular thanks to the return of Joffrey Lauvergne from injury. Žalgiris also won the 2022 King Mindaugas Cup, beating BC Lietkabelis 91–66 in the finals.

Žalgiris was the first team to refuse to play against Russian teams in the EuroLeague (CSKA Moscow, Kazan Unics, and Zenit St. Petersburg) due to the Russian invasion of Ukraine, even gaining criticism in the Russian press for being one of the reasons Russian teams got disqualified. They finished the EuroLeague season with a memorable 103–98 win against KK Crvena zvezda. Žalgiris finished the EuroLeague season with an 8–20 record, above the disqualified CSKA, UNICS, and Zenit, but still in last place of the eligible teams—their worst EuroLeague finish since the 2015–16 season.

By the start of April, disappointment returned to Žalgiris. Struggles in the LKL resulted in Žalgiris once again falling behind Rytas in the standings, and they ended up finishing behind Rytas in the standings for the first time since the 2013–14 season. Žalgiris replaced Zdovc later in the month, signing Lithuanian national basketball team coach Kazys Maksvytis as their new head coach. The struggles continued under Maksvytis, who failed to find a good lineup or rotation with the existing roster.

In the LKL playoffs, the struggles became even more evident. Žalgiris needed all five games to beat BC Neptūnas in the quarterfinals, narrowly winning the series 3–2. Žalgiris won the first semifinal game against BC Lietkabelis, before losing the next three games – Lietkabelis won the series 3–1. Žalgiris had failed to qualify to the LKL finals for the first time ever, ending their 11-year domination of the LKL and finishing the 2021–22 season with the biggest fiasco in team history. Žalgiris finished the season by winning the LKL bronze medal, beating BC Šiauliai in the consolation round in a 4–0 sweep. To add insult to injury, Rytas went on to win the LKL championship. Jankūnas retired after the season and became the sports director of Žalgiris.

After the disastrous 2021–2022 season, Žalgiris overwent a radical overhaul from the previous season. Coach Maksvytis had signed a long-term deal before the absolutely catastrophic ending in the LKL. Webster, Nebo, Blaževič, Miniotas, Milaknis, Strelnieks, Giffey, and Lauvergne all left the team during the summer. Former team captain Paulius Jankūnas remained, as a sporting director, assisting director Paulius Motiejūnas. Only a handful of players, among the key ones Lekavičius and Ulanovas, named team captain after Jankūnas and who signed long-term extensions, remained with the team. One of the biggest problems of the previous season was settled when Žalgiris signed Keenan Evans as the new point guard for the team. Kevarrius Hayes and former Žalgiris player Laurynas Birutis were signed to replace Lauvergne and Nebo as centers, Rolands Šmits was signed as a replacement for Jankūnas. Tomas Dimša, who had signed with Žalgiris as early as 2020, returned to the team. Dovydas Giedraitis, who played an incredible season with BC Lietkabelis, and who was one of the main reasons Lietkabelis beat Žalgiris the previous season, was bought out of his contract in Spain, where he was signed to Estudiantes Madrid, and was loaned to Lietkabelis by his team, and signed a long-term contract with Žalgiris. However, the biggest signings for Žalgiris, for the summer, were Arnas Butkevičius, Rytas captain and one of the most important parts of the Rytas 2022 LKL championship winning team, and Ignas Brazdeikis – former NBA player, standout in college, and who returned to play in Lithuania, both on the national team and for Žalgiris – for the first time since moving to Canada at a young age. Despite solid additions, the awful performances of the previous season haunted the team; while Žalgiris became an instant favorite to regain the LKL crown, in the Euroleague, the team was not even considered to be anywhere near playoff contention, with many experts predicting last place for Žalgiris in the Euroleague.

Despite this, and the fact that head coach Kazys Maksvytis had only a brief experience in the Euroleague (as head coach for Neptūnas Klaipėda in the 2014-2015 season), Žalgiris shocked the Euroleague; led by Evans, Žalgiris fought nearly every team, at home or away, to the deciding seconds, winning most of the matches. Keenan Evans dominated with incredible performances. In December, however, Evans suffered a season-ending achilles tendon injury; at this point, Žalgiris was 9-8 in the first round of the Euroleague, in playoff contention. While many believed this to be the end of Žalgiris's good run in the Euroleague, Žalgiris recovered – signing Isaiah Taylor, as the new point guard to replace Evans, and Achille Polonara, both from Efes – before the second round. Brazdeikis, who finally adjusted to the European game after a difficult first half of the season, became team leader, with Ulanovas, Šmits, Hayes, and, after a time of adjusting, Taylor and Polonara all contributing. Butkevičius quickly became a fan favorite for his amazing defence and his hustle, with the former Rytas captain becoming among the most popular players among Žalgiris fans. Mantas Kalnietis, remaining after disastrous season, ended up retiring in February and moving to back-office work with Žalgiris, mostly with the Žalgiris football team. Žalgiris was 15-15 by the start of April, and made an amazing run to the Euroleague playoffs, capped off with wins over Maccabi Tel Aviv at home and FC Bayern Munich away, to reach the playoffs, as the 7th seed, with a 19-15 record and with wins over Fenerbahçe and Baskonia Vitoria. Žalgiris also finished second in attendance, behind KK Partizan, with fans selling out 16 of the 17 home games, starting in October, because of which, the Žalgirio Arena became the host of the Euroleague Final Four tournament. In the Euroleague playoffs, Žalgiris faced off against FC Barcelona, coached by ex-Žalgiris coach Šarūnas Jasikevičius. Despite best efforts, and the fact that Žalgiris had beaten Barcelona in the regular season at home, Barcelona proved too much for Žalgiris, beating them 91-69, 89-81, and 77-66 for a victorious 3-0 sweep. However, the incredible performance of Žalgiris in the Euroleague earned the team a standing ovation in the last game in Kaunas.

Žalgiris won the 2023 edition of the King Mindaugas Cup, their fourth consecutive Cup victory, with Ulanovas once again being named the MVP of the finals. In the LKL, Žalgiris finished first in the regular season, with a win over defending LKL champions BC Rytas in April, and finished with a 28-5 record. In the playoffs, Žalgiris swept BC Nevėžis in the quarterfinals 2-0, to set up a rematch against BC Lietkabelis; this time, Žalgiris beat Lietkabelis 3-1 to avenge the previous season loss, with a satisfying, dominating 95-66 win in Panevėžys in the deciding game. In the LKL finals, Žalgiris faced Rytas, the series going a full five games, with Rytas giving Žalgiris a fight in each game, with Žalgiris beating Rytas in Kaunas, 108-93 and 95-80, but Rytas winning in Vilnius, 94-71 and 69-68, to set up a decisive fifth game in Kaunas. Žalgiris would win the deciding game 97-87, winning the series 3-2, and regaining the LKL championship. Taylor, who scored 32 points in the championship winning game, was named the LKL Finals MVP.

After an incredible 2022–2023 season, Žalgiris re-signed much of the team. However, Paulius Motiejūnas, club director since 2013, departed the team and headed to become the director of Euroleague Basketball, a move that many had anticipated during the 2023 season. Paulius Jankūnas took over as club director, in addition to being the sporting director. With Keenan Evans returning from injury, Žalgiris also made an unpopular decision not to re-sign Isaiah Taylor, the MVP of the LKL finals and Žalgiris leader during the victorious series against Rytas. Among other departing players, Tyler Cavanaugh and Karolis Lukošiūnas left during the summer. To replace Taylor, Žalgiris signed Naz Mitrou-Long to the point guard position and also signed Brady Manek, former NCAA standout, to a contract to replace the departed Cavanaugh. With much of the younger Žalgiris players, in particular Motiejus Krivas, departing to the NCAA, Žalgiris also signed Danielius Lavrinovičius, fresh off his career-best season with BC Nevėžis, to a contract.

With what seemed as solid additions during the summer, as well as keeping much of the same roster as the previous 2023 season, Žalgiris looked to continue where they left off the previous season. At the start of the season, however, Žalgiris suffered a massive blow as team leader Ignas Brazdeikis was bought out by Olympiakos Piraeus; the move became even more haunting when Žalgiris decided not to immediately search for Brazdeikis's replacement. Despite the departure by Brazdeikis, Žalgiris started the season strong, being undefeated in the LKL and 3-1 in the Euroleague, sparked by the incredible return to form by Keenan Evans. However, by October, the bottom fell out; struggling even in the LKL, Žalgiris completely fell apart in the Euroleague, going into the second round of the Euroleague with a disastrous 2-11 finish in the first. Mitrou-Long struggled as point guard, and by November, was also bought out by Olympiakos. The eventual replacement for Brazdeikis, Edmond Sumner, played too inconsistently to make any difference. Injuries hurt the team, in particular an injury to Arnas Butkevičius, one of Žalgiris top defensive players; his brief replacement, Austin Hollins, had a forgettable stint with Žalgiris. Rumours of Andrea Trinchieri coming in to replace coach Maksvytis began as early as December, followed by a reported player mutiny which resulted in Maksvytis remaining with Žalgiris for the time being. However, the tragic finish in the Euroleague first round, with a 5-12 record, resulted in Žalgiris and Maksvytis mutually parting ways by the end of December; and coach Trinchieri was brought in to replace him.

Under Trinchieri, Žalgiris had a ressurgence; in the second round of the Euroleague, Žalgiris returned to playoff contention, and fought for the final spot of the Euroleague Play-In tournament all the way to April. Laurynas Birutis became one of the best players for Žalgiris, completely overshadowing Kevarrius Hayes and taking over as starting center, and Dovydas Giedraitis became one of the best defensive players, not just for Žalgiris, but in the whole Euroleague. Lead by Evans, Žalgiris fought until April for a spot in the Play-In tournament, before an away loss to AS Monaco ended their hopes for Euroleague playoffs. Under Trinchieri, Žalgiris finished with a 9-8 record, going 14-20 overall. Keenan Evans had incredible performances all season, establishing himself as one of the top guards of the Euroleague.

Žalgiris also won the 2024 King Mindaugas Cup, held in Kaunas, beating BC Wolves in the quartefinals, BC Šiauliai in the semifinals, and BC Lietkabelis (who had eliminated BC Rytas in the semifinals) in the finals. Laurynas Birutis was named the tournament MVP. In the LKL, for most of the season, Žalgiris dominated, sweeping Rytas in the regular season, to finish with a 26-4 record, with no other team in the LKL coming close to Žalgiris. During the season, it also became clear that Žalgiris greatly relied on Keenan Evans. Žalgiris chose not to search for another point guard after Mitrou-Long departed in November, with only Lekavičius remaining in the spot. Žalgiris also made a dubious decision to re-sign Karolis Lukošiūnas in February, a decision that ended up even more questionable when Lukošiūnas, after playing a few games, was out for the whole season by the end of March. Before the end of the transfer table in the LKL, Žalgiris also signed Demetrie Rivers; while Rivers had some good games for Žalgiris in the LKL, he barely saw any playing time by the playoffs. In the playoffs, Žalgiris beat M-Basket Delamode Mažeikiai 2-0 in the quarterfinals. The semifinals, against BC Lietkabelis, was a nightmare; in the deciding game of the victorious 3-0 Žalgiris sweep to set up a rematch against Rytas, Evans suffered a season-ending injury by rupturing his patellar ligaments. Without Evans, Žalgiris fell apart. With nobody stepping up for Žalgiris in the finals, Rytas took advantage, taking home-court advantage away from Žalgiris, and finishing off the still shocked Žalgiris 3-1 in the LKL finals to regain the LKL title, while ending the already difficult season for Žalgiris in a complete fiasco. This win by Rytas over Žalgiris is considered the biggest upset in LKL history.
