The Patriots. Gronkowski will be back, and I guarantee that when the Giants pull double coverage, Brady will make them pay.
They have so many weapons, Hernandez who is a dual threat (TE/RB), Gronk, Welker, Edellman(who has returned kickoffs for TD's before.), Green Ellis+Woodhead(both who show signs of being good RB's), Ocho, who is showing that he is learning the playbook, and Branch. All these guys are under the command of Tom Brady.
Belichick and Brady will both be studying film like crazy, especially from the week 9 loss to the Giants, which was their last meeting.
Giants D is good, but I have a feeling that they could end up getting torn apart. Patriots D has looked fairly good in the Playoffs so far.
I think the Patriots win by at least 10.
