I think you have to keep most of, if not all, the defensive side of the ball. Giving Diaco 1 season to change an entire defense isn't easy and we've already started to see some positive results. Plus, we have strong coaching and recruiting from Parrella, Bray and Donte. I really like what is happening on that side of the ball.
Offensively, I say we have to keep Keith Williams. Great recruiter and one of the best WR coaches in football. Anytime you have NFL players coming to train with you in the off-season you are clearly doing something right.
I know that's probably unrealistic to keep that many people if MR is fired but that's why I'm in the opinion of keep MR one more year as long as he kicks out Langsdorf, Cav and Reggie Davis. Bet it all on next year. One slip up and he's gone. And that gives our new AD some time to truly assess our football program and the "MR vision" before making the biggest coaching change of his/ her life.
