They have a good offense, but I can rarely remember the Pats losing to anything besides an incredible defensive performance... especially in the playoffs. Seems like a bad matchup for them. Gotta rely on offense and hope the defense doesn't break. I think their offense will struggle, with New England's sound defense having two weeks to prepare. And Atlanta's defense is almost surely going to get lit up, as they have for most the season.
My score prediction: New England 38 - Atlanta 24
