I don't think you are going to find a lot of support for that idea coming from any AD's. Having those OOC games on campus is a big source of income. Say the average ticket price is $20, if they can draw 60,000 that would be $1.2 million. The gate from three home OOC games is going to cover a lot of costs. And if you throw in a neutral site game where you are guaranteed X amount of dollars, 4 OOC, or at least 3 for some conferences, it becomes almost a necessity to bring in the extra revenue.
Even for G5 schools, having the extra income from 4 OOC games is nice. IMO, we will have a much larger gate for an OOC game against Stanford, Georgia Tech, or UNC than we will for UConn, SMU, or Tulane.
