Big 10 will play in the Rose Bowl
SEC will play in the Sugar Bowl
ACC will play in the Orange Bowl
Big 12 will play in the Fiesta Bowl
Seed won't matter for where people play.
If BYU is the 3 seed, Fiesta Bowl.
If BYU is the 4 seed, Fiesta Bowl.
The only way BYU gets into the Rose Bowl is through the earlier round.
So, they go 12-1, losing the Big 12 championship game, but getting like the 12 seed and go on the road to Indiana or someone and win and then play Oregon or whoever wins the Big 10.
