I would actually like having Mike Gundy as a coach. That is, if he had a competent DC. He definitely has fire and sticks up for his players, and seems to be pretty good with the Xs and Os as well.
(Edit: This is assuming Scott Frost was never born.)
I think that Gundy is a darn good coach, and he is at least an honorable mention, but @Native is right that Ferentz would never made this list because he's not very entertaining. I think that he's a pretty good coach though.Not going to be a Ferentz on this list. Ever.
