What isn't important is what some uninformed-fan-base source has to say on the subject.
What drives Ferentz's popularity among fans? It doesn't seem to be a winning team. Last year's team didn't perform to expectations, yet fans' zeal for Ferentz hasn't wained. Instead, fans shift blame to other areas.
If Ferentz suggested his defensive coordinator retire - even more so, without also suggesting his offensive coordinator retire, Ferentz's popularity among fans would wain.
What doesn't make Ferentz popular among fans is keeping his entire coaching staff intact.
I don't get it. What does having a family atmosphere have to do with winning?
I agree that some people are critical of KF for his loyalty to his coordinators, but after 2007 KF was on the hotseat with a number of fans. His ability to turn the team around after rough patches seems to maintain his popularity.
As for your other question, some recruits (and their families) look for a strong family atmosphere when choosing where to attend college. If they are going to travel a great distance, they need a stable support system to make it through the first year or four of college. So without good recruits from other areas we would have less "winning."
