Me, I dislike the whole rankings thing. I say run it just like you run the AAA High School Football playoffs in your home state. Obviously, statewide, year to year, some regional subdivisions are stronger than others. But, such is life. The winners then compete in the playoffs. It is simple, and there is no guesswork. Whoever wins the games goes on to compete further past the regular season. But that is just me. And if that was the case, then this would just be a mid-season poll, and would not really matter.
As it is, all UW (or really any team) can do is show up on game day and keep winning. Hopefully, if they do, it will be recognized. The pundits say that the "committee" (gawd I hate that. some group of dudes in a room making decisions, rather than scores), will "highly regard" conference winners. Whatever that means.
