I can't really see UT leaving for the SEC. Or CU leaving for Pac 10. I could be wrong, hope I'm not.
What I see as a most likely scenario-
Utah
BYU
KSU
KSU
ISU
CU
UT
OU
OSU
TTech
Baylor
A&M
If this doesn't happen, I see KSU, KU, Tech, and OSU joining the BCS MWC. Either of which I'd take. Would be amazing to get to see KSU at Air Force.
