I have no problem with Grill standing up for one of his guys. Pretty soft T, but the refs were trying to get control of the game.
I think the whole thing was probably called correctly. A F2 was justified on the WVU player, and I don't think there's any doubt Jaz kicked his legs knowing they were tangled up. At that point Grill saw the WVU standing over Jaz and reacted, which I guess I kind of get. Jaz had just gotten clocked then had the guy standing over him and you've got to protect your guy.
Did the WVU player also get a T on top of the F2? I missed that part and honestly I have no idea how it would have played into the freethrows/possession. He definitely deserved one on top of the F2 for standing over Jaz like that.
