I think what you're overlooking is that college football is totally different animal than NFL, and in many ways the college game is more complex than NFL for a HC, as he has to deal with many off-field issues including recruiting, player's academics, dealing with boosters and, unlike NFL, you have a finite number of full-time coaches allowed on staff....lots of seemingly "overqualified" NFL coaches have taken a stab at the game only to get humbled, and often unceremoniously fired...look at Al Groh with his Parcells/Bellichik connections, same with Dan Henning, Charlie Weiss, Monte Kiffin, Mike Sherman, John Bunting, Paul Hackett, Jim Mora,etc...of course there are exceptions like Jim Harbaugh and, to be fair, Herm Edwards is approaching his job with respect to the college game, hiring many college coaches...but history has not been kind to NFL coaches in the college game....I don't get the infatuation with a coach just because he coached on Sundays.
