Between the 1979–80 season and the 1981–82 season, the Celtics had lost to the Philadelphia 76ers in the Eastern Conference Finals two out of three times, mainly because physical Sixers guard Andrew Toney routinely caused problems for their defensively fragile backcourt. After subsequently getting swept by the Bucks in the 1982–83 Eastern Conference Semifinals, Celtics general manager Red Auerbach added the perennial All-Defensive Team member Johnson to his squad, hoping that Johnson would help the Celtics fare better in the Eastern Conference playoffs (particularly against the 76ers). Johnson joined a squad that included Hall of Fame forwards Larry Bird and Kevin McHale and Hall of Fame center Robert Parish, a trio that has been described as the best NBA frontcourt of all time. Johnson described joining the Celtics as a "dream come true" and enjoyed the tutelage of highly successful general manager Auerbach, who was "living history" according to Johnson.
