1987 Eastern Conference Finals

The Celtics established themselves earlier in the decade, with 4 Eastern Conference titles from 1981–86. But the emergence of the younger Pistons was the first real threat to the Celtics' dynasty. The Bad Boys, as Detroit was known, used physical play to intimidate their way to victory. This roused the ire of Boston's players and fans, and the teams' mutual hatred of each other often led to on-court fighting. Detroit's biggest antagonists were Bill Laimbeer, Rick Mahorn and Dennis Rodman. In Game 3, Bird and Laimbeer were ejected for fighting as the Pistons won 122–104.

The most famous moment of the rivalry occurred during Game 5. Leading 107-106 with 5 seconds left, and Detroit threatening to take a 3–2 series lead, Isiah Thomas had his inbounds pass stolen by Bird, who dished it off to Dennis Johnson for the winning layup. With Parish forced to sit out Game 6 due to a suspension for punching Laimbeer in the second quarter of Game 5 (the first for a playoff game in NBA history; he also re-sprained his right ankle late in Game 5), the Pistons won Game 6 113–105 to send it back to Boston for Game 7. The Celtics ended the bitter series with a 117–114 win in Boston Garden over Detroit.

• Game 1: Celtics 104, Pistons 91
• Game 2: Celtics 110, Pistons 101

Boston wins series 4–3.

1988 Eastern Conference Finals

Thomas got his revenge in the 1988 Eastern Conference Finals. The Pistons finally unseated the Celtics, winning the series 4–2 and advancing to the NBA Finals to face the Lakers. What was notable was the fact that Detroit, who entered the series with 21 straight losses at the Boston Garden, beat Boston by winning 2 of 3 there (Games 1 and 5). In Game 5, the Celtics led by 16 before the Pistons rallied to win 102–96 in OT. In addition, their rough play and intense defense made Bird's scoring drop to just 10 points per game on 35.1% shooting, forcing Boston to rely on McHale.
