I hate it when refs or umpires mess up important games. And worse yet, when they call something that should never have been called in the first place. The Ohio State-Miami NC game is the first that comes to mind. A Big 12 ref, who was supposed to have been on probation in the first place, throws a pass interference flag on a clean play that should have ended the game. The Miami players react to the play, and then out comes the flag. I'm no Miami fan in any way, shape or form, but you have to admit what actually happened to them.
