So this is the 7
St. Johns (NYC)
Seton Hall (North Jersey)
Villanova (Philly)
Georgetown (D.C.)
Depaul (Chicago)
Marquette (Milwaukee)
Providence (R.I.)
It seems pretty clear they are going to go after Xavier (Cincinnati). So the question is how many more do they try to add. I think they should go to 12 for optimum value. Given the markets those 8 have, I think they will go after Butler (Indianapolis), Charlotte, Creighton (IA), and St. Louis.
So they could do an East and West
West - Marquette, Depaul, St. Louis, Xavier, Butler, Creighton
East - Charlotte, Georgetown, St. Johns, Seton Hall, Villanova, Providence
Clearly they could target some other schools instead of St. Louis and Creighton so they could compact a bit more schools such as Dayton, Richmond, Virginia Commonwealth would all make sense. UMass might as well but they just added a FBS football school so that might cause problems.
