The Seattle Seahawks No. 1-ranked defense faces a serious threat in the Philadelphia Eagles No. 4-ranked offense. Every level of the defense will be tested by the Eagles' improving ground game and the surprisingly strong passing game led by Mark Sanchez.
The Eagles have also managed to quietly work their way into being the league's top special teams unit and a big-play defense. A win for the Seahawks would move both teams to a 9-4 record and give Seattle the opportunity to move into a tie for the NFC West division lead.
