Kazlauskas is considered to be one of the best coaches from Europe. In the past, he has coached Lithuania's top two pro club basketball teams, Žalgiris Kaunas (1994–2000) and Lietuvos rytas Vilnius (2001–2004). In October 2004, he became the head coach of Olympiacos Piraeus,[1] and later moved to CSKA Moscow during the 2010–11 season.[2]
Kazlauskas returned to the Southern Tigers as head coach for the 2017–18 CBA season, while Du was serving as head coach with the "China Blue" version of the country's national team, and led a rebuilding side to third place with 28 wins in 38 regular season games before the youthful squad were eliminated in the semi-finals of the 2018 CBA Playoffs. He handed the head coaching job back to Du after the season.
From 2009 to 2010, Kazlauskas served as the head coach of the Greek national team and guided them to bronze medals at EuroBasket 2009. In 2012, he returned to Lithuanian national team and guided them to consecutive silver medals at 2013 and 2015 EuroBasket tournaments. In 2016, Kazlauskas left the team for the second time after his 4-year contract expired after the 2016 Summer Olympics.[6]
Note: The EuroLeague is not the only competition in which the team played during the season. He also coached in domestic competition, and regional competition if applicable.
