Yahoo said earlier today that Pete Carroll was the dream candidate.
I don't doubt that Harbaugh says or thinks he likes the pro game better than the college game. But that's only half the story seems to me. What if he is just temperamentally better suited to the college game? He very much seems to be a guy who is hard to work with and wears out his welcome in a few years. Better to do that with college kids, who I) are only around a few years and II) are only 18-22, and therefore more likely to tolerate an authoritarian figure, anyway....
I kinda would rather he stay in college, though I don't really care one way or the other. There are 3 "giants" in college coaching, IMO - Saban, Meyer, Harbaugh......
