Weak. Refs punish KG because they didn't do their job.
Ball don't lie.
And did anyone see the wink from Chalmers, I'm not even sure how much of that elbow it connected. From behind KG it looks like it connected, but the view on KG's right (which they only showed once), looks like Chalmers flopped without elbow even connecting.
Not to mention Turiaf's reaction after KG dunked on him earlier in the game, and Battier's shoulders/pushes/tangles after whistle was called. None of them were called, I just don't see how this is fair.
