With a coach that old, I'll be interested in his staff. He'll need a legit OC and some recruiters. I wouldn't be shocked if he pulls a Snyder-like "getting the band back together" with former players and coaches.
In his first year, Les Miles will be recruiting players that were 6 or 7 when he won his title. KU will be, at best, competing with Vandy for players in SEC country.
