You know, the more I think about it, the more I am liking the option of Tommy Rees. He has 4 years of experience as an OC at major college football programs. He's extremely young at 31, so he should have lots of energy for recruiting. And he should relate well to players. His time at Notre Dame and Alabama means he has spent time recruiting key areas we need to recruit well. And that also means he's had multiple years of establishing relationships with recruits, most of them high end talents. He might be able to steer some of those UK's way.
The only negatives I can find with hiring someone so young is the fact that he has lots of ambition and like Coen, may not stick around long. Being young, he may also be less likely to stand his ground and be willing to bump heads with Stoops when it comes to managing his offense. These are two areas where an older guy like Moorhead might be a better option. But recruiting is so important that the strengths of a guy like Rees may trump the experience of Moorhead, who isn't very personable.
