Offensively, I would keep everyone except Jason Michaels, who can't seem to utilize the TE's any better, and Greg Adkins, the O-line coach whose line gets softer every successive year. The rest of these guys seem to be able to recruit. I would hire a good QB coach to go with my new O-line coach who would return to man blocking instead of zone blocking.
Defensively, I would retain all of the assistants including John Chavis. Chavis would be the link to past Vol greatness. The rest of the guys are doing well at recruiting. I would hire a full-time special teams coach like Shane Beamer instead of dividing ST duties.
