The Packers are a different team today than they were through the first half of the season last year. Since the Tampa loss, this team has been hot. It went toe-to-toe with both Arizona and Pittsburgh on the road. Yes they loss, but you can't argue that they were overwhelmed by either team.
They also beat Dallas. Not only beat them, but handled them pretty well. Dallas was hot at the time. The next week they followed up with a win against San Francisco, who finished the season 5-3 in their last eight games.
Finally, Green Bay beat Baltimore in a cold weather game. That's a team built to come to Lambeau and beat the Pack, but they didn't. The Ravens went on the road in the postseason and hammered New England.
In between all the examples I gave, the Packers handled Detroit, Seattle, and Arizona.
The one close game they against a poor team was Chicago, but even then, it's on the road against your hated rival. You throw out the records in that one. Everyone always does.
This team is a top four team in the NFC. Minnesota, New Orleans, Dallas, and Green Bay is the class of the NFC. There is always another team in the conference that will come out of the shadows and emerge as a contender as well, but Green Bay is there. Make no mistake about it. The Tampa loss actually changed this team for the better.
