Game: Philadelphia 76ers @ Boston Celtics
The 76ers and Celtics had one of the most heated rivalries of the 1980s, meeting in the playoffs seemingly every year and developing legitimate bad blood. Julius Erving and Larry Bird were not just the stars of the 76ers and Celtics, respectively, but were also often right in the middle of the antagonism between the two sides. Things boiled over here in this regular season matchup early in the 1984 season, as some jostling between Bird and Erving turned into a full-on pileup as Moses Malone and Charles Barkley held Bird so Dr. J could get in a free punch. The fight also led to this iconic image, a favorite of both 76er and Celtic fans and a reflection of just how much the two squads detested one another.
