Steve Kerr had reason to be frustrated heading into this third-quarter timeout, as the Cavs had just completed a 7-0 run to get within four points of his Warriors, and he was convinced Tristan Thompson should have been called for a loose ball foul before converting the latest bucket.

Still, this seems like a lot of rage for a guy whose team is in fine shape right now.
