What's the argument for wanting UW to win?

It isn't strong but if we were to beat UW, their win over Oregon would give the Ducks two losses so we could lose two more conference games (Utah and Cal, for example) and still be ahead of them on head to head. (Under that scenario we'd also need UW to lose another game.) 

But, of course, the same is true of Oregon beating UW, giving us some more margin with the Dawgs. So, not much reason. The "Ducks beat UW to open up the possibility of a three way tie for first if UW beats us and all three run the rest of the table" argument still is good. I think.
