Following the resignation of Rick Pitino, the Celtics saw modest improvement under coach Jim O'Brien. Paul Pierce matured into an NBA star and was ably complemented by Antoine Walker and the other players acquired over the years. While the team was 12–21 when Pitino left, O'Brien's record to finish the season was 24–24. Following the 2000–01 season O'Brien was given the job of head coach on a permanent basis. As a result of numerous trades, the Celtics had three picks in the 2001 NBA draft. They selected Joe Johnson, Joe Forte, and Kedrick Brown. Only Johnson managed to succeed in the NBA, becoming a perennial All-Star after leaving the Celtics.
