I think Campbell is overhyped in a way. He has done really great things at ISU. Really reset the expectations of ISU coaches and players and helped us become a more respectable football program.
Where he is overhyped is in they way he has changed some in our fan base. Some people are so "hyped" by what he has helped us achieve, that they no longer are happy with a bowl, or 7 wins or 8 wins or having great players like Purdy, Kolar, Hall or incredible coaches like Heacock. They are ready to fire coaches and come down hard on players at the first sign that they don't meet their overhyped expectations.
I believe that Campbell is the real deal. That if we keep him, we will eventually become more of a solid team and every once in a while win the conference and maybe get a shot at that 12 team championship they are talking about. Who would have EVER had those expectations before Matt?
He, his coaching staff and players will probably never be satisfied with that, and I love that attitude. But, if that is all he is able to achieve for me and my school. If he takes us to a bowl almost every year and keeps us in the top of the "new big 12" more years than not, I will be much happier as a fan than I was for the last 42 years (the first 3 were pretty good honestly.)
He has had success and spoiled some with less perspective I think. That is the overhyping I'm talking about. I hope we as a fan base can keep our desire and drive without becoming the flaming ******** that other teams' fan bases are. We should want more, but we should keep a realistic and honest humbleness on our way to achieving it.
