Which would be the rationale for teams from the C-USA wanting to join the Big East.
But if the CUSA and MWC play their proposed title game, they're more likely to get a BCS bid than even the Big East with a few CUSA teams added.
Counting TCU there were 9 teams in that league. Two are to the ACC for sure and likely 4. Of the 5 left I'm guessing 2-4 get absorbed by the Big 12.
Any Big East team left, 1-3 of them, could have BCS access through CUSA/MWC mega conference. Frankly if ISU were in that position I'd prefer that to being in a conference of Temple, Navy, Army, ECU, Villanova and South Florida.
The mega conference will have teams like Boise State, Fresno St., Nevada, AFA, Hawaii, Houston, Southern Miss, Memphis, SMU, UCF and possibly South Florida. That's higher football prestige than what the Big East can hope to hold together with service academies, Temple, and too quick on the trigger ECU.
