Where they rank on defense: Week 13

Posted by ESPN.com's Mike Sando

The 49ers jumped two spots into the NFL's top five in red zone defense after holding the Bills to a field goal in Week 13.

The Cardinals fell five spots to 31st in the same category.

Super Bowl teams have often fielded highly ranked red zone defenses recently, something to keep in mind as Arizona moves toward the playoffs.

In an upset, Seattle has allowed fewer points than any NFC West team this season.

Where NFC West defenses finished in yards allowed last season: Seattle 15, Arizona 17, St. Louis 21 and San Francisco 25.
