Input: Question: When did Mikan start playing in the NBA? Passage:The Lakers were founded as the Detroit Gems in 1946 before relocating to Minneapolis, Minnesota and renaming themselves the Lakers (Minnesota's nickname is "The Land of 10,000 Lakes"). The club won several titles led by center George Mikan in the 1950s before moving to Los Angeles in 1960. In 1972 they won another championship led by center Wilt Chamberlain and point guard Jerry West. After acquiring center Kareem Abdul-Jabbar in 1975 and point guard Magic Johnson in 1979, the Lakers built a team that won 5 titles in the 1980s. With the retirement of Johnson and Abdul-Jabbar, they struggled in the 1990s. However, in 1996 the club acquired free agent center Shaquille O'Neal and traded with the Charlotte Hornets for newly drafted shooting guard Kobe Bryant. With the two maturing under coach Phil Jackson, the club turned into a contender in the early 2000s.
