The AFC is looking like it will be fun too, especially the AFC West with the Raiders, Chiefs, and Broncos scrambling for the division crown. But I really think the only position spot I could see changing is the Ravens. Neither the Dolphins or Bills will leapfrog the Chiefs/Raiders/Broncos for a wildcard spot. Chargers maybe, I like them a lot, but they have dug themselves a hole.
NFC, on the other hand, looks WIDE open. You could make an argument that every division outside of the NFC South is legit up for grabs. There are 9 teams within one game of the #6 seed. The NFC North is basically a 3 way tie. Cowboys have the Giants right on their tail. This conference has the makings of one hell of a finish.
