A two-time scoring champion and a dominant force inside, O'Neal teamed with Kobe Bryant to win three straight NBA titles with the Lakers before joining Dwyane Wade and the Heat for a championship run in 2006. A 15-time All-Star, O'Neal won NBA MVP in the 1999-2000 season and led the NBA in player efficiency rating for five straight seasons (1997-2002).
