Everybody says that Kiffen wants another HC but I haven't heard him say that. After his last tenure at Southern Cal, I have to wonder if he isn't one of those coaches who is a fantastic assistant coach but not quite so as a head coach.
Miami is not a good job for any head coach. I compare it to the South Carolina job, I think those two jobs will make the best of coaches look very average or below compared to coaching at other schools.
True. Miami fans have inflated expectations, but the school has put little money into facilities, they play their games away from campus, and they lack the glam of Clemson or FSU in the ACC. It's not a very attractive job for coaches with other options.
All of these schools would be better options than Miami:
South Carolina at least supports the program, and Spurrier has improved SC's reputation, but you still have to recruit against Florida and Georgia, and convince players from those states to move to Carolina.
I think the VA Tech job is a good one, and Memphis' coach was wise to take it. Following Beamer could be tough, but he's had a few down seasons to lower expectations.
Missouri might not be a bad job. You're not solely competing for the same recruits as Florida or Georgia, although in theory it should be hard to compete with the talent that comes out of those states.
USC job -- a coach should be fine for a few seasons as long as he remains sober and acts like an adult. The available talent alone guarantees a solid team. Eventually the fans will want a championship, although expectations have finally tempered to a more realistic level after the past few years. Of course, this job is unavailable for Kiffin.
Memphis. This job would be a better than Miami for Kiffin, a chance to prove himself in a non-Power5 Conference as a head coach before seeking to move up.
As J says, Kiffin has said nothing about wanting to be a head coach, but no coach should declare in public his intentions while he has a job. I'm not sure Kiffin is head coaching material either, but I question whether he realizes that.
