It’s not too often that the NFL’s No. 1 offense faces its No. 1 defense. In fact, this meeting between the Patriots and Seahawks is the first time such a matchup has occurred in Week 6 or later in the season since New England’s own No. 1 offense beat up on the Steelers No. 1 defense 34-13 on Dec. 9, 2007 at Gillette Stadium.
