I'll say it again - do you want an average coach at Iowa State or an above average coach?
The entire purpose of firing and hiring coaches is to find above average coaches, right? We have enough data to show that Steve Prohm isn't an above average coach - would anyone disagree with that? I could make the case that he's below average or even average - but, for me as a fan, that't not good enough and I want more. That doesn't mean I expect more Sweet 16s, Final 4s, or conference titles. But I do expect us to not finish dead last or second to last 2 out of 3 years.
Are you saying that because Matt Campbell has Iowa State football where it is, if he left, we should go back to hoping for one bowl game per decade and losing seasons 3 out of 5 years? Because historically, that's where Iowa State football has been. Hoiberg, just like Matt Campbell, raised the bar for Iowa State athletics. And I don't think we should settle for "well historically we have been worse so this coach is doing just fine". That's a loser mentality.
