I had this discussion with a buddy - I think there is something to these guys striking when the iron is hot or it becomes too late at these "big but middle tier" programs.
He could've gone anywhere he wanted that year they got to like 10 wins and took down...Penn St. But he didn't, wanted to display loyalty for the first time in his career, and now it seems like no one calls. Then they come back on the other end and spin it to "I'm here because I want to be here my whole career" No, you didn't go when you could, and now you're not shiny anymore so no one calls.
Same thing with Matt Campbell. No one wants to spend their whole fucking career in Ames, IA. No one. But, he thought he'd get Notre Dame when it opened up, so he sat, and now it seems like he doesn't even get invited to the party anymore. Your options are 1) strike when it's hot 2) SUSTAIN that success that made you talked about or 3) Really be humble enough to stay in that spot.
I don't think these guys get where they are out of supreme humility that makes them "stop chasing", what I think happens is you see Matt Campbell go 9-3 at Cockeye Fucking State, and you go WOW! INCREDIBLE! Then he stays, and you see him go 4-8 a couple times and you say "hmm - maybe he should stay there"
