So the Sugar Bowl is a possibility. But the preface to everything is the CFP will “consider” which means historical ties may not be the sole factor. I do think the Fiesta and Sugar are the only ones in play for us, however.
I am not sure whether the CFP committee would want to give a geographical preference to BYU or whether it feels BYU itself has no connections to the Sugar Bowl. Not really sure. I would assume BYU would prefer the Fiesta Bowl for proximity reasons but who knows how they work this.
The least likely to me is the Peach Bowl and it would take highly unusual and unlikely circumstances to get the Rose. The B1G champion would have to be the fifth highest ranked champion and thus be off the table for the quarter finals - which isn’t happening.
