If I'm FSU I'd look at Leach or Gus Malzhan maybe one of the former SC coordinators (Sark, Kiffen). I'd definitely gauge Miles interest.
If I'm SC I'd look to the NFL at names like Saleh, Josh McDaniels, or Eric Bienemy. If that didn't work I'd try to get Cristobal from Oregon, Peterson from Washington, or Malzahn from Auburn. I also think Mike Gundy from Oklahoma State is a good coach.
