They did it again this week. Ohio State will probably be perceived as "piling on" with that last TD, but I think they just meant to run the clock out. MSU just couldn't stop that last run.
I do like the instant replay in the last two minutes. I think all conferences should adopt that. Things that happen in the last two minutes could affect the outcome more than something that happens in, say, early 3rd quarter. If they limit it to the last two minutes, I have no problem with instant replay in college football.
