If I'm the AD, these are some of the calls I would probably make:
Urban Meyer
Steve Spurrier
Mack Brown
The skeleton of Bear Bryant (or at least his houndstooth hat)
Buck, Berry, Mills and Stipe
Phil Jackson
Rick Pitino
Bill Clinton
Bobby Bowden
Tommy Bowden
Terry Bowden
Denzel Washington
Ron Zook (pysche!)
Rick Neuheisel (just to laugh uproariously at him)
Jenny McCarthy
Ace Frehley
Sammy Hagar
Of course, if you're the AD and looking for candidates, let's talk. But quickly, I'm considering some opportunities at the CIA as well.
