What a difference a week makes.
Coming into Sunday's game against Pittsburgh, the Seattle Seahawks, after 10 weeks, were on the outside looking in on the NFC playoff picture. Following their win, accompanied by Atlanta's loss at Minnesota and Indianapolis' victory over Tampa Bay, the Hawks, if the season ended today, would qualify for the last Wild Card slot. Not only that, if they run the table and win their last five contests, they could still vault to as high as the second-seeded team and secure a first-round bye as well as a home game.

It gets convoluted and is highly unlikely, but it is, indeed, possible.  Here's how:
A.) Win out
B.) Arizona Cardinals lose to Green Bay in Week 16 (besides losing to Seattle in Week 17) accompanied by two more losses of their remaining three games (@ St. Louis, vs. Minnesota, @ Philadelphia)
C.) Green Bay loses two games out of their other four (@ Detroit, vs. Dallas, @ Oakland, vs. Minnesota)


The New York Times has created an unbelievable playoff scenario calculator that can be used to identify any team's chances of qualifying for the post-season.  As it stands now, Seattle has a 99 percent chance of making it based on winning the rest of their games.
