Kemba Walker said nothing happened in the locker room and agreed that the Celtics didn't compete in the third quarter. The limited minutes weren't part of the plan he said, and the C's need to simply get back out and make plays. Walker scored 23 points on 9-for-19 shooting with seven rebounds and three assists in a bounce back game, but he and Jayson Tatum combined for more turnovers (10) than the entire Heat team committed.
