It's a long shot now, but it may make sense in the long run. Right now, a few states are split have teams in each conference.
NC has ECU/Charlotte
FL has USF/FAU, FIU
TN has Memphis/MTSU
TX has SMU/Rice, North Texas, UTSA
LA has Tulane/La Tech
The AAC has little to offer. They are firmly on the same level with CUSA and the Sun Belt which also has teams in NC, LA, and TX. Can you really argue that ECU is better off playing SMU than playing App and Charlotte? Wouldn't Tulane be better off establishing conference rivalries with La Tech, LA-Monroe, and LA-Lafayette?
