Nice work guys, I have a few suggestions...
ACC- Appeared stable until the recent Big 12 realignment and SEC expansion developments. If the ACC were to lose schools to the SEC or Big Ten, the likely replacement would come from the pool of Big East schools including Syracuse, UConn, Rutgers, Pittsburgh, WVU, Louisville, and even Temple as a longshot.
Big East- Is actively looking to expand to 10 football members, could consider football expansion to 12, but would prefer football only candidates. If the SEC expands, there will likely be trickle down with the Big East losing schools to ACC, SEC, Big 12, and the Big Ten.
There is also a possibility that the Big East football schools could leave and form a new all sports conference leaving the non-football Big East yo expand by adding 2-4 members such as Xavier, Dayton, Richmond, Charlotte, St. Louis, etc.
CUSA - Stable but members could be targeted by several other conferences such as the Big East (Houston, UCF, Memphis, ECU), Big 12 (Houston, SMU), and the Mountain West. Should CUSA need to add replacements, potential candidates include North Texas, Temple, Charlotte, MTSU, Louisiana Tech, ULL, Troy, UTSA, Texas St., New Mexico St., FAU and FIU. CUSA could also be a landing spot for many of the Big East and Big 12 leftovers after the super conferences form including Kansas, K St, Iowa St, Baylor, TCU, USF, Cinncy, and Louisville.
MAC - Western Kentucky, Iowa St, MTSU as longshot options... could also be a home for Villanova football if they ever upgrade to FBS without a Big East invitation.
Sun Belt- Currently at 10 football members and 11 for all sports. Could consider current WAC members Louisiana Tech and New Mexico St or FCS upgrades like App St if they look to expand to 12 football members. UNCC could join as a football only member after completing their upgrade to FBS, keeping all other sports in the A10 like Temple and UMass.
Fan of the Big 12 Conference, the Mountain West Conference and...
