In that scenario:
We lose to ASU or Houston:
KSU top seed based on conference SOS
BYU 2 seed based on record vs common opponents wtih ISU/Colorado: Baylor, KSU, Central Florida, Utah, Kansas.
We'd be 5-0 and Colorado and ISU 4-1.
If we lose Kansas, then it goes off them as the only common opponent. We'd be 0-1 and KSU, ISU and CU all 1-0.
If we lose to Utah or Central Florida we should still be in depending on KSU's SOS. Because since we'd all be 4-1 vs the common opponents if KSU SOS go them out of hte tie first, then our win vs them woudl be the next game looked at. But that's dependent on what the rest of KSU's schedule does.
Basically: Cheer AGAINST Colorado
