It won't matter. Every team outside of a few outliers is really constrained by the availability in the local market and too much population has shifted south for a program like Iowa to ever really contend for anything. We had a team in 2009 that could have hung with anyone, that was likely the high water mark for Iowa football.
Unless you can steadily land stellar dudes out of Florida, Georgia and Texas and then keep those dudes in the modern world, you ain't gonna win huge games. The problems Iowa has are extremely prevalent with every program in our region, but Nebraska seemingly has started to throw money at the issue and maybe they can turn it around. I really don't see Iowa doing much beyond a moderate upside surprise once or twice a decade no matter who the coach is.
