i expect Washington to take a big step back. 7-5/8-4 type beat.
USC is a bit of an unknown, though I expect them to have a winning record. a narrative that has gained legs is that USC simply had the fortune of having Caleb Williams at QB. i believe that is partially true. it has become so popular to dunk on Lincoln Riley that many have forgotten he essentially saved Bob Stoops from having an ugly end to his OU tenure. Riley gets the most out of his QBs, i don't expect them to fall back to mediocrity under him the way many do. they will compete in the big games and likely win a fair number of them.
Oregon is not going to look much different in my opinion. Lanning is building them like an SEC team, and i have a suspicion that a lot of QBs are going to look great in that system.
