Chris Bosh and the four Celtics

MIAMI -- It’s never too early for playoff mind games.

At the East All-Star practice last Saturday, Celtics coach Doc Rivers ran through some plays with Heat forward Chris Bosh on the floor alongside Boston's four All-Stars: Rajon Rondo, Ray Allen, Paul Pierce and Kevin Garnett. Rivers later used that lineup in the game.

During the workout, the Celtics players attempted to have some fun with Bosh by calling and then running through some of the Heat’s basic plays that include Bosh. It was a bit of a joke, but also a nod that the Celtics are studying their rivals.

“It was cute, it was real cute,” Bosh said after the Heat’s practice Monday night. “They got it wrong though. Those must have been old Toronto plays because they just passed it to me and moved out of the way.”

Bosh tried to get into the act, responding by calling some of the Celtics plays he knew.

“I didn’t have any power out there because I wanted to run a couple of their sets and they were like, 'What?'” Bosh said. “I was like, 'I know what the play is, let’s run "point."' And nobody said anything. It was all jokes. But I was serious.”
