to go with the "core". There is a clear top 3 right now with 2 from the core (ISU and KSU) and 1 from the new (BYU), and then the clear worst team in the conference right now is from the new (Houston).

Could also look at it this way:

Iowa St vs BYU
Kansas St vs Colorado
Texas Tech vs Cincinnati
West Virginia vs Arizona St
Baylor vs UCF
TCU vs Utah
Oklahoma St vs Arizona
Kansas vs Houston

Who would win more matchups? It would be close with some matchups going either way, but I'd probably give the core schools a 5-3 edge overall.
