When Frost fired four offensive assistants last year,
Trev went on record saying he didn't mandate that Frost fire anyone. He also said it was the head coach's job to have a vision and execute the strategy for it.
That doesn't sound like the kind of guy who's going to sit across from a candidate and mandate he retain a previous coach, regardless of how good any of us think that coach is or isn't. Unless, of course, Trev is manipulative and/or a liar.
What Coleman said doesn't mean anything to me. Was Frost out on the recruiting trail last year telling recruits 'well, you know, I may not be back next year or even survive the whole season’? Do you think any coach on a hot seat does that? Highly, highly unlikely. Frost or any coach in that situation would've sold themselves as a head coach for the future alongside a long term vision for the player.
That's probably exactly what Mickey is doing, as well. You lock the kid down and get him to commit. Then, you deal with retention down the road if you have to. Recruits aren't going to commit somewhere if they're confident that coach is going to be gone, and coaches aren't going to sit there and tell the kid the may be gone, either. The latter would be incredibly moronic.
