Laimbeer was drafted by the Cleveland Cavaliers in 1979. He played professionally in Italy for Pinti Inox Brescia, where he averaged 21.1 points and 12.5 rebounds, before returning to play for the Cavaliers in 1980. On February 16, 1982, he was traded to the Detroit Pistons, where he would remain for the rest of his career. During his playing career, Laimbeer was one of the most notorious players in the NBA. While highly popular among Piston fans, Laimbeer was despised by opposing players and fans for his disdain of his opponents, his poor sportsmanship, and his dangerous play such as repeatedly committing violent intentional fouls. In the public eye, Laimbeer's reputation for physical play tended to overshadow his skills. His former teammate Dennis Rodman noted this in his book Bad As I Wanna Be, saying, "[Laimbeer] was more than a thug, but that's what he'll be remembered for." In an interview for the 1990 NBA Home Video release "Pure Pistons," teammate Isiah Thomas also talked about Laimbeer's effect on opposing players, saying, "He frustrates people," but then added, "He frustrates people...because he's strong."
