The race for the NFC 6th seed really is very interesting. Arizona holds it only because Detroit is in the mix. Detroit knocks Minnesota out, and Arz beat Detroit head-to-head. If (when) the Lions lose this weekend, and both Arz & Min win, the Vikings would take over the 6th seed, by virtue of a better conference record. I expect Min to hold it outright however, because Sea should beat Arz.
Washington sits ½ game back, praying for all of them to lose, plus the Saints, Eagles and Panthers as well. Wsh holds head to head tie-breakers over Arz & Det and still has to play the Vikings.
