I'm not excusing KG at all, he needs to settle down and just play, BUT... my take on that play was pretty clear. He missed the shot and in the course of going up for the rebound, Zaza put his arm over KG's shoulder and held him down, then also was holding his arm with his other hand. KG was upset that no foul was called and raised his elbow, which happened to be into Zaza's body. There was a slight push off, but the close up angles showed that Zaza clearly flopped back, there is no way KG's slight elbow pushed a 7', 280lb. goon that far back. It's all inconsequential now, but it would be terrible if that no call led to suspensions for KG/Perk. Again, I'm not trying to excuse KG and he gets too chippy too often, but in this case it was an obvious foul on Zaza that went uncalled and then a flop on Zaza, which led to his own overreaction and instigation of the fracas. If KG gets a suspension out of that, it would be one of the more disappointing string of events of I've seen in a long time.
I know the suspension talks are for the ref contact, not the fray with Zaza, but the whole altercation would never have happened without 3 bush league moves by Zaza (and one by KG). [dang], what a stupid name Zaza is anyway.
