The Seahawks are in.
Minnesota has to win next week against the Bears, which they could do if Chicago rests their starters. They most likely will if the Rams win today, which would give them nothing to play for next week. They aren't getting a bye week if the Rams beat a bad Cards team.
In my predictions, I have us facing Seattle and then Chicago for the NFC title game. Dallas isn't winning a playoff game, no way. Jason Garrett is still the head coach, so you can bet on them finding a way to screw it up.
