The only institutions the AAC should ever consider as partial members is the service academies and that is as FB members only. You either bring the whole array of sports or you don't become a member. Period. Full Stop.
First, that's dumb.
You want Army?
Second, there's no one out there who is a) a worthy addition in all sports, and b) willing to come. No one. Everyone you'd want has been asked and has given an unequivocal no.
Third, we have 11 all sports members and a horrific basketball problem. We had two programs in the RPI top 50 - those matchups are a metric for the selection committee. We only had three programs in the top 100 and we had three over 200. That's a disaster - in hoops, they talk about a Power Six and we're not included.
So you gotta make a change. You have VCU, Dayton or Wichita. Given those three, you have one real choice and that's Wichita. That is the only school that you're dead certain will invest major conference money into their basketball program.
Plus, they're willing to cheat a little which makes them more appealing in this day and age.
