Well, in 2003, Nebraska got beat up pretty bad in the second half by Missouri, and pretty much trashed by Texas and K-State in those games. Would Rodgers have been enough of a spark to win two of those three games?
Texas on the road with Vince Young probably not, K-State at home, I don't know, but it certainly would have been closer with a qb like Rodgers. Missouri? Complete collapse after totally dominating the first half, Rodgers may have been able to steer the offense in the right direction to get the win.
