Big East in Basketball will be fine. Even if Uconn and rutgers jump they still have:
Louisville
St johns
Cinci
Villanova
West Virg
Marquette
Seton Hall
Providence
Depaul
South Florida
That is still a very strong conf. And eliminating 4 eastern teams may improve their recruiting.
If UConn & Rutgers go to the ACC & if Texas, Tx Tech, Oklahoma, and Ok St bolt the Big 12 -- have to think WVU, Louisville, Cincy, TCU merge with Iowa St, Kansas, Kansas St, Baylor, Missouri (If they don't end up in the SEC or Big 10) and create a new conference. The Big East would become a much different basketball-focused conference.
