NKR it isn't happening.
Expansion has been all about the $$$.
B1G expansion has been Rutgers/Maryland who were added for cable boxes and $$$, Nebraska was added because of its top 10 FB brand.
ACC expansion has been in 2003 to get a FB conference championship game with Miami, BC, VPI, in 2011 it was to rectify a shortsighted ESPN TV contract signed in 2010. The ACC needed expansion to go from 14 million dollars per school to 20 million dollars per school, and Louisville was selected because their FB potential was better than UConn's FB potential.
SEC expansion was about getting into TX for recruiting, and $$$ from new TV markets for an SEC Network. Mizzou was chosen over WVU because they were a better brand and gave the SEC new TV markets in St. Louis and the rest of Missouri.
Big XII expansion was done after the conference lost Colorado, Nebraska, Texas A&M, Missouri and they chose TCU to give the conference a TX replacement for A&M and WVU was chosen because they were willingly to help the Big XII keep their TV contract and get into the conference for 2011 when the conference needed their membership immediately. WVU was seen as a better FB brand than Louisville.
Pac-12 expansion was done to get the Pac-12 into new markets for a Pac-12 network.
UConn would be in the ACC if the Football schools FSU and Clemson didn't cash in political capital and get the ACC to add a better FB school than UConn. FSU and Clemson didn't want another BB first school and UConn will never be a FB school. SU/Pitt had WAY more history and national respect in FB than UConn. UConn won't even be the next AAC school to leave IMO. The Big XII will likely add 2 of Cincy, UCF, USF, BYU in the future. If BB mattered then UConn would be gone. You gotta tip your cap to their 4th title, but it isn't going to make a difference as the ACC won't add another member till Notre Dame commits fulltime or another team leaves after the GOR expires.
