Probably but UNLV fits the AAC model of large markets. And they play in a new NFL stadium. Plus they have some name recognition.
Hard to know exactly what qualities the AAC would be targeting in any possible expansion. There are a few others from the MWC who, depending on criteria, could make a solid case to be added. Fresno St, Utah St, San Jose St, Colorado St, & New Mexico. Some are bigger stretches than others.
Ideally, we'd add SDSU but they are too far out on an island by themselves.
