I have heard HC at Cocke Co., OC at Clinton & DC at South Doyle. If these are the candidates you are looking at an OC & DC that have helped rebuild the programs they are at & are coming off good seasons at their respected schools. The HC brings HC experience, but I am pretty sure the other two guys have that as well. Cocke Co. hasn't won many games under their HC, but he does have college coaching experience, so that makes his resume look good.
I think all 3 would be good hires & I am sure there are others that I are in the race, these are just a few I heard about....assuming my sources are correct.
