 They nearly accomplished this prediction of a sweep of all three rounds, only losing one game (to Milwaukee in the Eastern Conference Finals) en route to the championship.The Sixers set a record for highest winning percentage in the playoffs that was not broken until the Lakers went 15–1 in 2001.The Lakers' mark, however, came after the expansion to the current 16-team, four-round playoff format, which was first implemented in the 1984 playoffs, while the Sixers avoided the first round by virtue of their top seeding.
