The greatest concern for me in this game is the Packers defense. It's one thing to stifle a mistake-prone Cutler or Sanchez, quite another to get turnovers off Brady and the Pats. I also haven't heard anything new about the status of Nick Perry. He's important because he allowed Matthews to move inside and bolster the run defense and play roamer. If Perry is not ready to go on Sunday, that will make the Pats running game that much harder to defend. And pressuring Brady is not going to be easy either.
I do think the Packer defense is better than the start of the season, but I'm not sold on them yet. For the Packers to win they will need to make at least a few stops against the Brady Bunch. I don't have all the confidence in the world that they will be able to.
The Packers will score. I'd be very surprised if they did not put up at least 27-28 points and probably more, but i don't see the Pats scoring any less than 30 against this defense either.
Offensively, I think the Packers can match or even exceed the Pats' firepower. Defensively, the Pats have the edge. Their secondary is as good as ours--we are stronger across the board with Shields, Williams, Hayward, Burnett and Dix, but we don't have anyone of Revis' caliber, and Browner and McCourty are both pretty good, and their front 7 is better IMO, especially at ILB.
