I have no problem with us doing 2-for-1's with the CUSA opponents like Memphis, Tulane, UAB, Houston or USM. The travel time isn't too bad for our fans and I agree, there are a great deal of upper-tier FBS schools doing that sort of thing. Doing a 2-for-1 with SMU or Tulsa or a decent Mountain West opponent on the road wouldn't be bad either.
The only Sun Belt school that we should be playing on the road is South Alabama, as it's a relatively short trip for our fans and you can make a nice trip out of it as there are plenty of things to do in the area down there, unlike playing somewhere like Ruston, Monroe, Troy or Jonesboro. Even Murfreesboro is terrible, as Nashville is nearby. But in other case, there have to be other options out there like bringing in a MAC school (like we're doing with Bowling Green) to fill an open date on the schedule.
And there is an ever-growing number of FBS teams as well. UT-San Antonio, Texas State and UMass are all going to be FBS soon, as will UNC-Charlotte a few years down the road. There's no reason we shouldn't be able to get one of those types of teams to come play at our place without having to return the favor.
