For me, this OC hire is probably one of the most challenging I've see in a while. There are just no "no-brainer" options out there. The ones who fit the QB development role don't have play calling experience. The ones who fit both roles well, as just not viable candidates. For example, Tee Martin is just not ever coming to the Vols. In fact, I would be shocked if he ever left California because of his wife's career. Jim Bob Cooter would be perfect, but he is already being mentioned as a future NFL head coach. Just don't believe that college coaching is an option for him unless it is as a head coach. Helfrich just doesn't seem to be a good fit for the range of needs for the job, specifically play calling. Kelly is not one I would ever consider. My preferred candidate, LaFleur doesn't have play calling experience. On the surface, this hire would seem, but there are so many complicating factors. Throw on top that Jones wants to keep his basic offense in tack with some enhancements, finding the right candidate is tough.
