Two of the league's elite defenses go at it Sunday when the Philadelphia Eagles (14-3) host the Minnesota Vikings (14-3) in the conference title game.
The Vikings allowed the fewest yards (275.9) and fewest points (15.8) per game. The Eagles were fourth in yards allowed (306.5) and fourth in points (18.4).
"Typically, when you're good defensively, you're going to stay in the ballgames," Vikings coach Mike Zimmer said. "Then you have a chance to win them at the end."
Minnesota has three Pro Bowl players on defense: end Everson Griffen, outside linebacker Anthony Barr and cornerback Xavier Rhodes.
