and either Bama or South Carolina (almost assuredly, Bama). From the Big Ten it is going to be PSU, OSU and Oregon. From the ACC it is going to me Miami and either Clemson or SMU. Then you have Notre Dame and BSU. That leaves one spot for the Big 12.
So for BYU to get in they need to unseat Bama/ South Carolina or OSU.
Ain’t happening.
