BYU and Boise State are the two most profitable of the G5 programs so they should be 1-2, UCF comes in not far down (I posted this in another thread with the Wall Street Journal rankings. I think BYU was 60, Boise 63, and UCF 65. Cincinnati was 77).
After those 3, it gets interesting for spot #4. You say Cincinnati but USF, Memphis, UAB, and East Carolina all make more money. Also, Army would be a nice add close to West Virginia, has a National interest, and is Independent so no buy-outs. The Service Academies could be all good pickups for the Big12.
