Not convinced that Carolina will be as good. Tampa Bay could be the sleeper in the division though. It's not like they were completely lacking in talent and Lovie is an experienced coach that can put build a defense.
I'm just not very high on the NFC North. I think it's the weakest division in the NFC. The Vikings wen 5-10-1 last year. They were not swept by any team in their division. Basically the NFC North was bad enough that the Vikings were able to compete in it. They were 2-3-1 in their division. Packers may be the best team in their division but they aren't the 5th best team in the league. Even with adding Peppers, a healthy Rodgers, Matthews, and Cobb.
