I actually mentioned this possibility to some friends a while back. I didn't think Denny got quite enough respect when he was in the NFL, and I bet he'd make a good college coach. There are a number of reasons it might not work, but it's an interesting idea.
I know this will seem arbitrary to a lot of people, and I'm not 100% sure where my motivation is coming from (or if this is a P.C. thing to say) but I'd like to see an african american coach here. I don't doubt that they're under-represented in the coaching ranks, and it follows that there's a lot of untapped talent in the population because of it. Beyond that, it would be nice to contribute to that change in the NCAA culture...and I can think of a number of african american coaches off the top of my head that I would love to see on our sidelines next season.
