Tressel is the best coach and recruiter on that list.
With pretty much all up and coming coaches out of the picture and no Gruden in sight... which coach of the 3 with checkered pasts is the best fit?
I would go with (in this order) Tressel, Petrino, Davis.
Davis I'm not impressed with I feel like it could be a Kiffin 2.0 experience with us running him out of town after a few .500 seasons.
Tressel would be a big hit the first season with the sanctions and maybe show some desperation but I think he would make us forget that in the long run. It wouldn't look great PR wise but then we have 6 months to forget about all that til kickoff. He would be a solid hire but may be too much like Bruce Pearl for the University/Hart.
Petrino while maybe a good coach is a clown. The whole motorcycle incident shows his intelligence. That with the whole Atlanta Falcons deal shows his character. I'd be afraid this guy really could screw things up and leave us both in shambles and a laughing stock.
Tressel:Got to go with Tressel in spite of NCAA show cause. He's the most consistent winner. After winning 3 NCs in Division 1-AA, stepped up to Division 1-A and went to 8 BCS bowls in 10 years. I don't think a resurrected Bear Bryant could come in to Tennessee and go to a BCS bowl next year, so it is worth it to let Tressel sit out the first 5 games, knowing that chances are really good that a BCS bowl is forthcoming in a couple or three years.
