Minnesota faces Green Bay in week 17.
Bears are slumping and face Cardinals and Lions both on the road.
Washington is hot but they host Dallas in week 17 and Dallas is also hot.
So there is a decent chance the Seahawks could back in. Seattle would have to lose to the Rams at home (and SF at home) for this even to matter. Football outsiders currently gives the Seahawks a 99% chance for the postseason. Sounds about right to me.
