I think the NFC isn't quite as up for grabs a as people think. I think it's largely a matter of who between Tampa, NO and Green Bay is going to make it.
Outside of those 3, Seattle and the Rams will be in the mix but they aren't really playing anyone yet and to me make up the middle tier. Chicago also has a good record but ia running into a part of the schedule that will expose them coming up soon.
The AFC on the other hand has a bunch of good teams. KC, Buffalo, Baltimore, Tennessee, Pittsburgh, Cleveland, Indianapolis and Las Vegas are 8 teams for seven spots.
