Yes? And? Nebraska was not a johnny come lately to big boy football. Before Osborne as coach there was Bob Devaney and his .829 winning percentage. And while Nebraska does not have AU's advantages I'd be willing to argue it also does not have our disadvantages. The REC is real. The way things work in this state at least since 1972 is that it's all good as long as AU doesn't get "too big for its britches." Compete? Sure. Gain a lasting upper hand? With Saban, the REC and their protector Emmert at the NCCA, not allowed. I used "not allowed" advisedly.
In addition, AU is in the strongest division in the strongest league in the history of college football. It's gotten to where a recruiting class that is merely top 10 is a relative failure. If AU lands the 10th ranked class, we are likely no better than 3rd in the SEC West.
I can't speak to the near campus advantage. I do know this, If we judge by corn, Nebraska is far ahead.
