The Celtics want Kevin Garnett to be more aggressive, as he attempted only 12 shots in Friday's loss to the Sixers.
During the playoffs, Boston is 4-0 in games in which Garnett attempts 16 or more shots.
"I think we counted nine times where he was trying to be a passer instead of a scorer. So we gotta get him back, mentally, to attacking," said Rivers. "They didn’t trap as much as you thought. We just gotta continue to force feed him and keep him aggressive. But we also have to get into our stuff quicker, like we did in the first half. Kevin didn’t touch the ball a lot, but we had an 18-point lead, so something was going well."
Garnett dismissed the notion that he’s struggling to score against Lavoy Allen.
"All the big guys are playing physical and bumping," said Garnett. "You go through side-picks, it’s physical; I can’t tell one guy from the next. Spencer Hawes is being just as physical as the young kid (Allen). It’s all the same."
