Butch went 50-27 (33-12) at two mid-major schools before he came to Tennessee, including 4 conference titles. Central Michigan and Cincinnati have both been messes since he left; I imagine both of those schools wouldn't mind having him back. He can be successful at a lower level of college football - he has before. I don't think he's cut out for basically any P5 job. If he is cut out for one, it'd have to be at a place with really low expectations.
Even at a big boy school like Tennessee, he didn't have any trouble recruiting. He certainly didn't fail at Tennessee because he couldn't attract talent. Butch's problem is that at this level, he was average at best (and horrible at worst) at basically every aspect of coaching other than recruiting. That's why he failed. If you place him at a level of CFB that isn't as competitive, he can be a pretty good coach.
