In the 1989–90 season, Detroit lost perennial defensive forward Rick Mahorn when he was taken by the Minnesota Timberwolves in that year's expansion draft and ended up on the Philadelphia 76ers when the Pistons could not reacquire him. It was feared that the loss of Mahorn – average in talent, but high on hustle and widely considered a vital cog of the "Bad Boys" teams – would diminish the Pistons' spirit, but Rodman seamlessly took over his role. He went on to win his first big individual accolade. Averaging 8. 8 points and 9. 7 rebounds while starting in the last 43 regular season games, he established himself as the best defensive player in the game; during this period, the Pistons won 59 games, and Rodman was lauded by the NBA "for his defense and rebounding skills, which were unparalleled in the league". For his feats, he won the NBA Defensive Player of the Year Award; he also connected on a . 595 field goal percentage, best in the league. In the 1990 playoffs, the Pistons beat the Bulls again, and in the 1990 NBA Finals, Detroit met the Portland Trail Blazers. Rodman suffered from an injured ankle and was often replaced by Mark Aguirre, but even without his defensive hustle, Detroit beat Portland in five games and claimed their second title.
