While the fact that they're opening against Seattle is overall stupid, the Packers really did get lucky with their 2014 schedule. They only have to play against 2 good teams on the road, so, in my opinion, they should be able to win 12+ games as long as they stay somewhat healthy. It's not guaranteed, but yea, it's likely.
I mean, the Pack beating the Seahawks or Saints probably won't happen since Green Bay never does that kinda thing, but besides those the whole list of contests looks like a gift. The Jets, Vikings, Lions, Bears, Eagles and Falcons definitely won't win at Lambeau no matter how bad the Packers play those days, while their other two home opponents (the Patriots and Panthers) will put up nothing but a fight. They'll score 20+ points and make it close, but in the end I don't see any way the Packers drop those games.
As for the road half of the schedule, as I've already said, I don't see Green Bay winning in Week 1 or 8, but I still see them going 6-2 away from Lambeau. Not because they'll necessarily play well, but simply because they're playing weak hosts. I mean really, the Dolphins, Bucs, and Bills? The league can do better than that, can't they?
