It's been a while since I put any real thought into this, because I know it isn't happening at all, but w/ everyone else wishcasting, I'll throw this one out there:
HC: Jim Leavitt
Current DC @ SMU
Former HC @ USF - he started the program and had solid results from Day 1:

OC: Kevin Kelley
Current HC @ Presbyterian (FCS)
Former HC @ Pulaski Academy (HS) - the guy who never punts:

That would give us the older, established head coach who knows what it takes to run a program and has experience coaching in Texas. As well as an exciting offense that's going to score points.
