First, Fulmer isnt going anywhere. Yes, he will make changes. No, it wont be either of his Coordinators.
Second, no HS coach has a shot at the UT position. AT least, not right out of High School.
Third, Chavis, as far as I am concerned, is the next in line for UT's Head Coach. He has shown his loyality and skill to UT.
Fourth, if you think a successful NFL coach would leave his position to go to a university position, you need to get a clue. Thats like getting a Masters degree to go out and become a janitor. The college ranks are full of former NFL head coaches. But they were terrible NFL coaches. June Jones, Pete Carroll, tell me what they did in the NFL. NOTHING! Thats why they are in the college ranks.
