Take things to a logical conclusion. He can't beat Alabama which he has equal talent to in a lot of years.
You think he can win against a team like Florida which will totally outclass us in a few years, regardless of how good a recruiter the next coach is? You think there is anything in him that will let him upset a better team?
What I see is a man who knows how to do one thing on offense: Let the piledrivers on the offensive line knock people around, and give the ball to the tailback.
Only thing is when he can't do that (see Bama) he has nothing.
So if Les Miles came here, how would you expect it to play out? What would you expect to see on a yearly basis?
What's more I don't think any premier program would hire him. You can't win it all at LSU consistently, no way you are doing it at Texas, at Georgia, or any of the other usual candidates.
It's Herman's world now, and Les Miles is just hanging around in it now.
