I think New England will be down this year, and by down I mean "not 16-0"
Towards the end of last year, everyone had the secret recipe to beat the Patriots, and the Giants actually pulled it off (almost twice). I don't know of any earth-shattering changes they made in the offseason (and why should they have to?).
I think the Pats will finish up 13-3 or about there but choke it off in the playoffs to the Colts.
In the NFC, I'm surprised anyone's picking the Eagles to do anything. They'll be lucky if they make the playoffs. I expect teams like Minnesota and Tampa Bay to surprise some people but I think its between the Cowboys and Seahawks for the NFC title.
I'm going to go with my official prediction:
Cowboys 31, Colts 27
