Won't play devil's advocate. I will only suggest that UConn to the SEC in a vacuum is senseless. UConn plus UNC, Duke and Virginia...has some logic to it. The B1G has Rutgers and Maryland, and covets VA and NC. The SEC is dominant across the south, but misses NC and VA. The SEC just needs one NY area foothold to increase carriage rates. If you look at the reconfigured SEC east after such a move, it isn't far off from the ACC geographic footprint.
East: UConn, UVA, UNC, Duke, USC, UGA, UF, Bama, Auburn, UK.
West: A&M, LSU, Ole Miss, MSU, Arkansas, Missouri, UTenn, Vandy.
Moving Bama and Auburn east balances the football hit from the new additions. The east would be a basketball powerhouse with Duke, UConn, UNC, Florida and UK. So you might need to swap UK and UT, and let UT and Vandy play a rivalry game. All of this assumes that the SEC would waive the one school per state concern for Duke. Applying the rule in the other states, UConn is the logical addition, Every other ACC school but Pitt, BC and Syracuse would be disqualified. We fit better than any of them. Oklahoma could work, but there is the GOR.
