If they have the means to do it, then they should do it. I have seen so many games in the past have questionable calls that could have been easily cleared up with replay. Why play a guessing game when video review can make it clear as day?

Classic Notre Dame vs St Pats chant:
"Parking Lot! Parking Lot!" or "Lets play Football!"
If you wanna see a spectacle of crowd chanting, you must attend a ND vs Pats game in your lifetime.
