The final AP and Coaches Polls had UW at No. 4, which is the same ranking UW had in the final playoffs poll. So, no the poll voters didn't really care about how how badly Bama beat UW. They did care about how USC won the Rose Bowl. USC ended up No. 3 in the AP and No. 5 in the Coaches Poll.
As far as the Rose Bowl goes, it's 2017 not 1975. The Rose Bowl is now part of the playoffs. Every 3rd year, the Rose Bowl hosts a playoff game. In the other years, if one of it's traditonal particpants is in another playoff bowl, the Rose Boel pciks the next most deserving team from the conference. The Rose Bowl has been doing this for almost 20 years now. Big whoop. It's still the Rose Bowl.
