By the time Les leaves, he will be the greatest coach all-time at LSU. I couldn't think of a better coach to name the field after.
Then he better get on the ball and start winning more SEC and NCs. If Bama wins the NC again this year, Les will be fighting an uphill battle against Saban for as long as he's around. Miles is good for at least one loss per season due to poor coaching (Bama this year). I think it's gonna be tough for him to win another NC. He will keep us in the big picture, but it will be largely due to talent and not his coaching prowess.
