Kirk Cousins and the Washington PFT beat the Giants on Thanksgiving, while Dak Prescott and the Cowboys look to be all but fully exposed without Ezekiel Elliott. I think that Washington, based on their intact team, better QB (at present - Dak could be better eventually but Kirk is definitely better now), will win this game.
I have a hard time picking the spread here because it's a divisional rivalry and those are much wilder than they should be.
Washington to win, keeping their playoff hopes alive (still slim) and effectively ending Dallas' season.
