Yahoo has an interesting site where you can enter wins, loses, and ties for this week to see how the games alter the playoff seeding.
While the 6 NFC teams are set, the seating is still really up for grabs from 2nd to 6th.
If the Cards win and Minn loses and Philly loses, Cards get #2 seed.
If the Cards win and either Minn or Philly lose, Cards get the #3 seed.
If they all three win or the cards lose, Cards get the #4 seed.
Philly and Dallas both have the potential to land anywhere from the #2 seed with a win to the #6 seed with a loss depending on the outcome of the other games. Interesting stuff.
