Down 17 at the Wells Fargo Center after one of their worst first halves of the season, Joe Mazzulla gave his Celtics starters a choice: Did they want to stay in the game, raise their effort level and try to rally against a Philadelphia 76ers team that was missing several of its top players?

The Celtics pulled off the biggest comeback in the NBA this season, rallying from a 26-point deficit Sunday night to defeat the undermanned 76ers 118–110 in Philadelphia. The comeback begin in full with three minutes remaining in the third quarter when the visitors started a 38-10 run over eight minutes that erased a 26-point deficit in full midway through the fourth quarter.
