Lucius Oliver Allen, Jr. (born September 26, 1947) is an American former professional basketball player. Prior to his National Basketball Association (NBA) career, he became an All-American as part of two of legendary coach John Wooden's UCLA NCAA Championship teams, in 1967 and 1968. The 1968 team, featuring three consensus All-Americans in Allen, Lew Alcindor (Kareem Abdul-Jabbar) and Mike Warren, is considered by many[who?] to be the greatest team in men's college basketball history. After being suspended for his senior year at UCLA for receiving a second citation for possessing a small quantity marijuana, Allen was drafted by the Seattle SuperSonics in the 1st round (3rd pick) of the 1969 NBA draft and retired in 1979. As a member of the 1971 Milwaukee Bucks team, which also featured UCLA teammate Alcindor, Allen earned an NBA championship ring. He also played with Abdul-Jabbar for two seasons, from 1975–77, in Los Angeles, but not winning a championship in either of those years. Allen was traded the following season to cross-town, Missouri-based Kansas City Kings, winning the division championship in 1979, and retired from basketball after that season.
After finishing his storied basketball career which included a high school state championship, college national championship, and an NBA championship, Allen turned his attention to coaching aspiring players in the Los Angeles area.
