Tee wouldn't be as bad as some think, especially as a walk around HC. He can fundraise and do the thing with the boosters while letting his OC and DC coach. May need to upgrade over Chaney, but Steele would be fine being HC of the defense. Most HC's are only as good as their assistants anyways so a figurehead who can play the game isn't a bad idea anyways.
Plus if anything comes of this investigation it won't really matter who the coach is next year. Giving Tee a one year trial run when TN is facing sanctions isn't a bad idea. Pretty much every guy that has been named on this board will be there next year, so is there really any hurry?
