I think Q-Rich was the reason it all happened, but KG's elbow was dumb and he deserves the suspension.
I don't really know what there was to explain. He threw an unnecessary elbow and deserved it. No matter how big of a douche Q was being, you don't need to be throwing elbows at someones head.
BTW, it's funny that Kobe didn't get suspended last year for an elbow to Artest's head, yet the Lakers fans are in here acting all high and mighty.
He just pushed with his arm (and elbow) the guy(s) that tried to hold him / and push him. You saw there were like 5 Heat players that got involved right away, and only Big Baby went in for help. KG will get his revenge game 3 for sure.
