(a) Butler and St. Louis would likely be the top two that fit with the Catholic 7. Remember, the whole (b) Catholic 7 really gives two craps about football, adding UC, Uconn, Temple, and Memphis you just added 4 "FBS" programs,(c) that was the big divide in the old Big East.
(a) Indeed, St. Louis would be another credible possibility.
(b) No... I'm saying for basketball only. Those schools, and especially Cincy and UConn are in a position right now to have strong influence on how the new BE shakes out, and arguably could work out a very-reasonably-solid situation between football with CUSA defectors and basketball with C7 schools.
(c) If you've read the quotes from the various C7 administrators, you know that their leaving is mainly rooted in the fact that they're outnumbered politically when the CUSA defectors join later this year, and they're persuaded it is to their advantage in the long run to not be having to deal with the flights of fancy that the football schools have... reference that the Tulane addition was what sent so many of them over the edge.
