Griff isn't innocent but he has a very punchable face, flops a lot, is flashy and in Hollywood, and as such a lot of players probably resent him. Maybe he acts like a douche or talks ****, I dunno. But as far as basketball goes, he doesn't get as many calls as you'd think for a guy who lives in the paint, and he gets beaten up a lot with no call. In this case, he wasn't really doing anything beyond the normal contact in the post and Bogut grabbed his jersey and pulled it up over his head. Wtf is Griff supposed to do?
I agree it was a ridiculous ejection, but Griffin bearhugged Bogut to start the play. Then Bogut went for his jersey and Blake pretty much backed off. It should have been a foul on Griffin and a T on Bogut.
