There is an old joke about a hired hand who got some whiskey from his boss. When asked how it was He said "just Right". If it was any worse I coulnd not drink it and if it was any better my boss would not have given it to me.
Les Miles is just right for LSU. If he talked any worse we wouldn't be able to understand him and if he talked any better some other school would steal him away from us. He is just right.
