@shorap: Faulty reasoning buddy. Just because the Cavs had other opportunities to win the game doesn't invalidate the importance of the charge reversal. Both Hill's missed free throw and JR's stupidity would've been inconsequential if the Warriors weren't given those 2 free throws.
Whether or not the refs did the right thing reversing the call is up for debate. The importance of that reversal on the outcome of the game is not.
