Enos is a better OC, than HC, and his time @ CMU proves that. It is obvious that he resigned from his HC job @ CMU with 2 yrs remaining on his deal, because it was very likely that a) he was going to be fired at the conclusion of the season or b) his contract was not going to be renewed/extended. It's important to understand that some coaches are better served/suited to be a coordinator than HC, and that shouldn't be viewed as a negative. Also..just because Enos's career trajectory portrays him as being transient, that doesn't necessarily mean his time @ MIA is also going to be short lived. When you look at his history more closely, it becomes clear that he moves strategically, and very seldom has he ever left a place without it being a vertical career move. Furthermore..when you begin to independently & objectively weigh the various factors/variables that determine whether a job is appealing, it becomes apparent that the MIA job is actually very unique, and one that is going to be difficult for Enos to leave.
1.) He is currently one of the highest paid assistants in all of college football.
2.) He is afforded complete control & autonomy over the Offense, and because he is working for an up & coming/1st time HC, his input is welcomed on a consistent basis. This is a sharp contrast from working for someone like Saban, who is notorious for being a micromanager.
3.) MIA provides him & his family a quality of life that rivals most places in the country.
So to recap-He won't leave to go be a HC at either the college or NFL level, because I seriously doubt whether he'll ever get one of those opportunities. He won't leave to go be an OC at another college, because as I've already mentioned he already has one of the best jobs in the country. Being an NFL OC someday could be appealing, but if the Barry Jackson article is factual, and he's in the coaching profession because he enjoys being a teacher/mentor then remaining in college may ultimately be his true calling.
