But could your grandmother out-recruit her predecessor, who had a national championship and, by the way, still had a pretty good product to sell?
DickRod's two previous HC tenures also included horrible first years. He is also transitioning to an entirely new offensive system (one he has perfected over decades), and has had to recruit players to fit that system. His incumbent starting QB transferred out, leaving him to start a walk-on last year, and a true freshman this year. His superiors didn't expect him to walk in the door and start winning Big Ten championships, especially considering the above.
Trust me, he'll be fine. He will probably be fired eventually (most coaches are), but it won't be anytime soon, and it certainly won't be this year.
