Boy, I'd love to see him in Athens in some capacity. He's never been a coordinator, but led Florida International to their first two bowl berths as a head coach. He's been at Alabama as the OL coach, played OL at Miami, has coached TEs and OL, and has is a pretty emotional guy.
I think we could do worse as OC, though I'd think we'll promote John Lilly before we'd hire Cristobal as OC.
Just a random thought on Christmas night.
