I think the Bills would chew up this Vikings team and spit them out.
GB is a good team but definitely has holes, and Zimmer has figured out how to exploit exactly zero of them. His offense has consisted of one nice pass that Cousins dropped into a thimble for Diggs to catch, and a bunch of Cousins running for his life while looking for exactly nobody. His defense has taken away exactly no GB weapons. There has been no trickery, aside from a Philly Special that even made WR Tom Brady look good by comparison.
Other than that, the Vikings are doing great tonight. They're a perfectly fine team that's likely to win 11 games and then get lit up like a christmas tree when it's cold as a Yeti's ass fur in Green Bay in two weeks.
