re: So after tonight, what does Les need to do with the staff?

I can think of two specific instances where a head coach legitimately removed himself from the offense after being actively involved previously.

Gary Patterson - Always a defense coach, but was involved with offense at TCU up until adopting the Air Raid a few years ago. Very successful move.

Tommy Tuberville - hired Tony Franklin at Auburn. The less said the better about this.

So be careful what you wish for, but there is upside.
