I disagree 100%. The Cards are not, and cannot be sneaky dangerous. They are too one dimensional to be sneaky, and I see no possible way they can win a game in Jersey in January, unless the weather is uncharacteristically un-January-ish and Spagnuolo gameplans to stop the non existent running attack and stacks ELEVEN in the box.
Of course, there is the possibilty that the Giants can play a sloppy game, let them hang around, and they can steal it, but I don't see that happening either.
