Trust me, you don't want to bring a high school coach to college. Takes time. Down here in Texas, Southlake Carroll High School has been a juggernaut for years. They have been ranked No. 1 in the country (but recently lost to school in miami). Their coach was Todd Dodge. He left for the University of North Texas. I know it is the first year, but good grief they are losing big time. Thing is, he looks like he is in over his head. And it's NORTH TEXAS!!!
I personally know Turner Gill, I believe he is a good coach, but he needs more experience. Give him an assistant position and groom him.
