I will agree that the NFC West isn't that great. Outside of it, Arizona (if my prediction is correct) will be 3-7. However, I'm betting on two things; one, the Cowboys have been choking in the playoffs as of late, & I think the same will happen, two, with Arizona coming off of an easy win @ home vs. Seattle, they'll have momentum along with homefield advantage.
As for the Pats, I'd love to see them do it, bu I doubt it'll happen.
If the Steelers represent the AFC, New York will have the upper hand. However, if Tennessee makes it, then I'll agree with you, Titans all the way.
