From what I've seen the last five years, there are very few college football coaches who make the mistakes that Bronco makes. Chances are pretty good, IMO, that we find somebody who puts together a more competent team. When the status quo is as low as Bronco has set it, it's fairly easy to find something better.
I guess one's willingness to take a risk in this situation would depend on how they assess the last 5 years.
