I think under normal circumstances, they should've called a foul on Gnoboli(?). But no way they are going to give that to Ariza. It's at best a non-call and the ball didn't go in anyway.
What I don't get is, if they decided not to call a time out, they at least should've gotten Fisher to the top of the key. But still, I don't understand why Kobe didn't take the last shot.
