If Dallas wants to win the super bowl this year they'd put in Romo over Prescott. I mean, I understand why they have Prescott in, but if your a super bowl contender, you should play your best players. Prescott can't throw the ball deep, which is going to be a problem. Also, I always thought the falcons were overlooked. They have a strong team this year. Honestly I think they're the ones going to the super bowl.
On the other side of the conference I think the AFC's quality of teams is a joke compared to the NFC. New England is New England, and they're always going to be a threat, but honestly I think people give them a little too much credit this year. I feel like this is the weakest New England team I can remember, and the reason their record is so good is nearly all of their wins came from .500 or below teams (except for The Broncos who, let's face it, at the end of the year were BAD, and the Steelers who didn't have Big Ben and were on a losing streak.) If the Pats were playing in the NFC this year, they'd have been eliminated.
In short, I think the Falcons are going to win it all especially if Dallas doesn't play Romo. Though the Pats might win it just cause it's the Pats.
