I mean in the AAC you have:
-UConn is an elite program
-Cincinnati is a perennial top 25 team
-Memphis and Temple who have some tradition of being very good teams, usually pretty consistent, too. Tulsa's probably the penultimate mediocre team.
-While it's kind of hard to say where SMU is right now, Houston and Tulane are doing a lot of the right things and should only stand to get better.
-UCF, USF and East Carolina are atrocious.
In the Big East you have:
-Villanova is an elite program
-Xavier, Creighton, Butler, Georgetown (less so) and Marquette are perennial top 25 teams
-Providence has a some tradition of being a very good team, fairly consistent.
-Seton Hall and St John's have been mostly bad, but at least have some tradition, some brand recognition and a natural rivalry with UConn.
-DePaul is, was and always will be awful.
I would have to think that in addition to the above comments that recruiting would be easier for KO in the Big East
because of the quality of opponents. This would help keep the quality of our BB program up while football can hopefully rebuild. Unfortunately, we may not be on the Big East's "top ten teams we'd like to have" list as others have mentioned.
So by going there we're with another elite program. Instead of one perennial top 25 opponent we have four or five. Even the bad teams are teams we have history with, geographic location, etc. You know - and Providence.
I DO think the AAC stands to continue to improve. I really do. But it's not the Big East and right now - I just don't think there's much of a discussion which place would be better for UConn hoops. There just isn't.
