Define "big". ND, Oklahoma, Florida, LSU and USC all just hired a coach (too bad about ND, supposedly Urban's dream job). Texas, Tennessee and Auburn just hired a coach last year. Ohio State and Michigan won't open unless their coach leaves for the NFL which I see as unlikely. Penn State and Michigan State just extended their coaches. That is a big chunk of the programs that would be on Ohio State's level in terms of prestige (and some on a level below). Obviously Bama and Clemson aren't opening up unless Saban retires/Debo leaves. I guess options would be Nebraska (lol) and Florida State. I suppose Oregon is in flux. They promoted their DC to be their head coach, but that doesn't seem to be a permanent thing. I think Urban is pretty toxic at this point as a coaching hire. He's got more than enough money to just sit around the rest of his life and do nothing. I suspect he may end up doing TV spots for Fox or ESPN.
