My guess is Peters starts. Probably Epstein as well. Rod had better have some scripted plays that take advantage of the weaknesses of the Nebraska defense so we get a quick start. Probing the defense to learn its weaknesses is not the way to go (saying this because it seems to me that Rod doesn't actually scout the next opponent, he tries to learn its weaknesses in the first quarter ).
So far as our defense goes, perhaps the older, more experienced players will make on-field adjustments while attempting to run the defense called in from the sideline.
