Northwestern has a tough D, but are they as good as Pitt or Wisco?-both of those games came with some schematic issues for Iowa. Traditionally NW is more base than the other 2. They have 2 good lbs, but their DL can be ran on. Also, I watched much of their Ball State game and their D was just not that impressive. You cold argue they shut down Stanford, but they also had ALL offseason to prepare. Remember what Norm could do with a month (Georgia Tech). In my mind it is going to take quite a few more breaks for NW to win, not saying it couldn't, but I think they have to get Iowa Vs Wiso lucky to win. I think Iowa wears them down in the end. I know statistically they are up there, but I think schematically Iowa is better prepared than usual to attack them (I.E. QB with strong arm-and doesn't lose games)
