In the 2007–08 season, Celtics completed the largest single-season turnaround in NBA history. The team went 66–16 in the regular season, a 42-game improvement over its 2006–07 record. However, the team struggled in the early rounds of the playoffs, needing seven games to defeat the Atlanta Hawks in the first round and another seven to defeat the Cleveland Cavaliers in the conference semifinals. The Celtics then beat the Detroit Pistons in six games in the Eastern Conference Finals, winning two road games.
