As it played out Saturday night, how many people were actually watching the Jo-Jo and Vaughn match up enough to have formulated an opinion? Maybe they showed it on the jumbotron, but at the end of the day, very few people could actually have a meaningful view of the play until videos started to circulate on the internet. Furthermore, as has been pointed out on the board, it was poor form for Whittingham to speculate on Kuthie's season-ending injury on someone tackling him from behind without knowing actually what happened.
"I need to look at the tape" is a perfectly reasonable answer, given how much we see or don't see in the moment.
