Within a few years, I see the Sun Belt expunging their non-FB schools, and adding two more FB playing schools:
Middle Tennessee State
The Sun Belt would adopt a format similar to the ACC for football. Here are the permanent cross-division rivalries:
Arkansas State-North Texas
Florida Atlantic-Florida International
Middle Tennessee State-Western Kentucky
Denver would go to the Summit League. As for the other 2 non-FB schools, I have them forming a new all-sports conference with several other non-FB schools in the South Central US:
Texas A&M-Corpus Christi
Texas-Arlington* (if they don't add FB)
Texas-San Antonio* (if they don't add FB)
The new conference would go by the name of the Trans America Athletic Conference.
A couple observations:
* Regardless of economic times, I'd think the Sunbelt would do what they could to cut back on travel costs...not increase it:
East: Florida Atlantic, Florida International, South Alabama, Troy, Western Kentucky, Middle Tennessee State
West: Louisiana-Lafayette, Louisiana-Monroe, Arkansas State, UTSA, Texas St., North Texas
* Lamar and UTSA have added football and will compete in the Southland. Both, along with Texas St., are hoping to upgrade to FBS.
