sixth consecutive year with 25.1 points per game, and Roy Tarpley won the NBA Sixth Man Award with averages of 13.5 points and 11.8 rebounds. The season saw the Mavs' deepest playoff run to date. They dispatched the Houston Rockets in four games and the Nuggets in six, leaving only the defending NBA Champion Lakers between them and their first-ever trip to the NBA Finals. The Mavericks gave the Lakers everything they could handle. Still, in the end, the more experienced Lakers prevailed, defeating Dallas in seven games on the way to eventually winning their second consecutive NBA Championship. Despite all the changes, the Mavs remained in contention. However, their season effectively ended when James Donaldson went down with a ruptured patella tendon on March 10, 1989, and missed the rest of the season. The Mavericks were left understaffed, demoralized, and disheartened as they finished with a 38–44 record. It was their first losing season since 1982–83—which was also the last time they missed the playoffs. The Mavericks returned to the playoffs in 1989–90 with a 47–35 record, but it was another season of off-court chaos. On November 15, only six games into the Mavs' season, Tarpley was arrested for driving while intoxicated and resisting arrest. The team started 5–6, and MacLeod was fired, replaced by assistant coach Richie Adubato. The Mavs finished the season with four straight victories to surge into the playoffs but went down rather meekly to the Portland Trail Blazers in three games. It would be the team's last winning season and playoff appearance until 2001. 1990–1998: Rebuilding 1990–1994: Free falling The team endured numerous changes in 1990, losing Sam Perkins to the Lakers via free agency and suffering injuries to practically their entire 1990–91 starting lineup. The players they managed to acquire—Rodney McCray, Fat Lever, and Alex English—were all in the twilight of their careers. On November 9, it was announced that Fat Lever would have season-ending surgery on his right knee, and that very night, Tarpley suffered a knee injury of his own, which ended his season. The Mavericks' season only got worse from there, and they finished with a record of 28–54, falling behind even the second-year Minnesota Timberwolves and Orlando Magic. In March 1991, Tarpley was charged with suspicion of driving while intoxicated and was suspended again by the NBA. It got even worse in 1991–92. Before the season even began, Tarpley
