I wish both college and the NFL would go away from the "must have indisputable evidence" approach to instant replay. If the goal is to get it right, it shouldn't matter what the initial call was. Slow things down, freeze frame and look at it objectively. Based on those advantages, with the newly available angles, how would you call the play.
It would also save us from the same "remember, it was called ____, so we need indisputable evid...." explanation which has become one of the most annoying things in the game. Yeah we know how it works. Thanks.
