To add 6 schools right now will decimate their per-school media value and basically admits that the AAC is simply the best of what's left from the 1995, 2005, and 2013 CUSA iterations:

1995 CUSA
South Florida
Memphis
Tulane
UAB
Charlotte (non-football, joined CUSA for football in '15)
ECU ('97)
*Southern Miss is the only remaining '95 CUSA school that won't have moved on

2005 CUSA
SMU
Tulsa
Rice
*Marshall and UTEP are the only remaining '05 CUSA schools that won't have moved on

2013 CUSA
FAU
North Texas
UTSA
*Apparently getting AAC bids ahead of Southern Miss, Marshall, and UTEP because of location...
