the cards are an interesting team. their defense is much better this year, they are able to get some heat on the quarterback. 20-1 is pretty good considering all the points you mentioned, but when it's nut-cut time i dont think they can stop the run. i also dont trust their running game to consistently convert on third and short.
im pretty sure the giants, vikings and falcons (yep!) can all go to zona and roll them. not sure about anyone else though (NFC). 20-1 is not bad, and if they continue to rush the passer and stay healthy theres an outside shot.
i like their chances a lot better than...
- indy +1525
- carolina +1425
- new england +1725
- san diego +1900
