On this date in 2008, the Boston Celtics defeated the Detroit Pistons to advance to their first NBA Finals since 1987 on their way to Banner 17.

On this day in Boston Celtics history, the team defeated the Detroit Pistons 89-81 in Game 6 of the 2008 Eastern Conference finals to advance to their first NBA Finals since 1987. They faced their longtime rival Los Angeles Lakers on their way to winning their 17th banner.

The Celtics beat the Pistons on the strength of their future Hall of Fame trio. Small forward Paul Pierce led the way with 27 points and 8 rebounds. Shooting guard Ray Allen contributed 17, and big man Kevin Garnett added 16 points and 6 rebounds. Detroit led by as many as 10 points in the final frame, but could not hold it. The Game 6 loss in the conference finals was their third such exit in three years.

“It’s kind of surreal,” Garnett said via ESPN. “Probably hasn’t even hit me yet because we haven’t slept in about four days, going on five days now. Going to the finals, I’m just hoping to get some sleep.”
