He would be the perfect hire for Auburn. Recruiting wise, coaching wise and with their situation I don't think they will attract anyone that is already in a big time position and successful to come and compete against Nick Saban in Alabama and the SEC. If they are "smart", pun intended, they will make him a very wealthy man.
The only thing I think he should be aware of and to contemplate before going there is will he be given full reigns of the team to do as he see's fit. I am sure coach Saban will give him the right advice and sure hope he doesn't go there. Would remind me of how coach Bryant didn't like seeing Pat Dye going to Auburn. But ultimately it will be his decision and where his ego lies will probably determine that.
