1.) This is the NFC East--you have to be able to pound it on the ground.
2.) At third and short, you need a running back who can grind out those couple of yards.
I'm not sure I agree with either of those propositions any more. I don't see any indication that taking it to the air won't be able to defeat NFC East opponents (heck, I'm reminded that the SEC used to be all about the ground game until SOS showed up). The only issue that I think comes into play is the weather, and frankly I don't think it necessitates that big a distinction. My feeling is that many people are dwelling in the tradition of the NFC East rather than the current situation.
As for point 2--if the team has been moving the ball well through the air on first and second down, I think they can do it on third down. Basically, they need to know they've got an automatic play--to the HB, to the TE, something--that will net them 2-3 yards every time. Or they just go long and try to convert on 4th down instead.

Thoughts?
