To say that LeBron James wasn't happy with Mario Chalmers during a timeout in the third quarter of the Pacers/Heat game last night would be an understatement. We don't know that we've ever seen King James get this upset at a teammate before. Sure, we've seen James and some of his Heat teammates yell at Chalmers in the past. But he looked like he was ready to physically attack Chalmers in the Heat huddle. It's unclear what Chalmers said or did to get this kind of reaction out of James but…wow. This could have went in a whooooooole different direction and been really bad for the Heat.

Fortunately, cooler heads prevailed and the Heat went on to win the game. But the incident didn't sit real well with James, who took to Twitter shortly after the game ended to address the situation:

Good to know. And we're glad to hear that this didn't escalate any further.
