Seattle basically gets to sleep walk all the way to the NFCC in that scenario. They get Arz or Atl in the Divisional round assuming Dallas beats Det.
We screwed ourselves w/ the Buffalo loss. We will get Dallas now instead of the cake walk they get. Then have to go to the hardest place to play for the NFCC.
The Bills loss was disappointing, but their defense is tough (they best Oakland yesterday if Dareus doesn't get hurt) and Orton won't win games but he also won't make killer mistakes to lose them either. The loses to Detroit and Seattle also were to legit teams. Those three loses were to teams that have lost once (Lions and Hawks) or three times (Bills) at home.
The one that killed them was to the Saints. The Saints have been awful, especially their defense. Maybe if Rodgers doesn't tweak his hamstring, things turn out differently, but what really killed them was to keep playing Hawk as many snaps as they were. That, and have Burnett miss that game are what may be the difference between a Super Bowl trip and an early exit (even assuming they beat the Lions).
