Teams have been pushing KG's number for a long time now. The thing is, it is a risky game. They do it to try to get him to get T's or thrown out of the game, but KG also plays significantly better basketball when he is pumped up like that. It doesn't throw him off his game, it makes him even more focussed...but it also makes him liable to throw a punch.
The thing that frustrates me is that if someone starts something with him and he walks away, he still gets a double T. This is the biggest cop out by the league. These guys know that they can get wrapped up with KG, and get the double T called nearly every time, not because KG reacts and does something, but because KG has a reputation (which is of course well deserved).
