Rajon Rondo was quiet in the first half. But once he finally scored in the third, he didn’t stop. Rondo scored 14 points in just over eight minutes. He and Kevin Garnett combined for all but six of the Celtics points in the quarter.

The Celtics have their largest lead, 74-67, going into the final 12 minutes. They did not commit a single turnover in the third. Garnett and Ray Allen are tied with a game-high 16 points. Elton Brand still leads the 76ers with 15 points.
