Seattle's path to the #2 seed is pretty simple: they need to win out, and they need the 49ers, Packers, and Giants to all lose one non-Seahawks game in the final 3. Consider then:
#1: Seattle plays Buffalo on the road. With all due respect to SF, Buffalo is Seattle's best chance for a loss in the final 3 games. If Seattle wins this game, I feel really good about finishing 11-5.
#2: San Francisco plays at New England. New England is the #1 team in the NFL in DVOA and just smoked the previously 11-1 Houston Texans. This is by far the hardest non-Seahawks game remaining on the schedule. It's almost inconcievable that SF would beat New England on the road but lose to Arizona at home in the final week. This game will pretty much decide the division and therefore Seattle's chance at a bye before the Seahawks even get their second shot at the 49ers.
#3: Green Bay plays at Chicago. If the Packers win this game, we might not catch them. Their week 16 game is at home against a bad Titans team, and their final game is on the road at Minnesota. I think Minnesota could maybe pull it off, but this weekend represents Seattle's best hope for Green Bay dropping a game and allowing the Golden Gate play to determine a tiebreaker.
#4: New York plays at Atlanta. The Giants are a very good road team and Atlanta is a paper tiger. That said they are an 11-2 paper tiger, and this might be the best chance for the Giants to drop a game we need them to lose. If the Giants and Seahawks both win out, the Giants will own the tiebreaker thanks to conference record. If the Giants beat Atlanta then there is still hope because they'll visit Baltimore the next week, and Baltimore is about as tough at home as Seattle is. Still, it would be nice if Atlanta took care of business for us.
Feeling greedy and lucky? If Atlanta loses out and Seattle wins out Seattle would own the tiebreaker. If you have confidence in Baltimore and think Atlanta is capable of losing at the Lions and at home to the Bucs, then you might want to pull for the Giants in this game and hope for Baltimore to beat them next week.
