Bears are dead, Lions are beyond dead, Vikings are all but dead for winning the division - the only thing holding that back is the fact that they and the Packers haven't played each other yet. While I would expect the Packers to win both games at this point, I wouldn't guarantee it, not between those two teams (Zimmer's always been the best in the division at beating the Packers, and the LaFleur Packers are 13-1 in the division...with the only loss being @Packers to the Vikings last year - hard to lose the division when you never lose your divisional games!). As for the Cowboys...yeah, that division is super dead, and you've beat the Eagles and Giants already, and I don't see much reason to expect Washington to have a chance in either games.
And so...all that matters is the #1 seed. The Cardinals were the greatest obstacle to the Packers in getting it and I had already thought it lost between the short week, our injuries, and playing @ there, but having beat them, I now believe the Packers can find a way beat anybody.
Buccaneers just lost to the Saints somehow, but they legitimately only have one decent opponent left in the Bills for the rest of the season. Really, their schedule is a joke - them losing to the Saints was super important for anybody else to be able to claim the #1 seed, I think.
Cardinals have a decent slate of opponents left, including the Rams, week 18 Seahawks (Wilson will probably be back), @49ers, and most pertinent to you, @Cowboys.
Rams have @Packers, vs. Titans, @Cardinals, vs. Seahawks (week 15), @Ravens, 2x49ers, @Vikings. That is quite the remaining schedule - pretty much impossible for them to win all those.
Cowboys have @Chiefs, vs. Raiders, vs. Cardinals for their remaining "difficult" games.
Packers have @Chiefs, 2xVikings, vs. Rams, @Ravens for their remaining "difficult" games.
Obviously, any team can drop any game any week - that's the nature of the NFL. But if I had to favor a team getting the #1 seed, I think I like the Buccaneers followed by the Cowboys best, especially because I think the Buccaneers are probably the most complete team (bizarrely bad defensive performance against the Saints notwithstanding), while I think the Cowboys are very likely to inexplicably drop one game to a bad team at some point in addition to likely losing at least a couple of their remaining "difficult" games...as well as having the losing head-to-head against the Buccaneers. After that, I'd probably tie Cardinals and Packers for next most likely, and then Rams the last - owing to their ridiculous remaining schedule.
