So money was the only reason? Personnel had nothing to do with it? We heard from one of our own players (a ND transfer) that they had crappy facilities back then, yet they were pretty good at that time.
It has become more and more of an “arms race” in college football. The practice bubble was state of the art at the time but became outdated. The new football practice facility is a huge step up. However Minnesota, Northwestern, and others are also building impressive facilities. That ND player you talk about was correct in that Iowa had fallen behind at that time. Yes, unfortunately $ play a HUGE role in the success of your FB program.
