Dallas is a much better team than Washington or the Giants. I wish the Giants had won that game last night, because you know they are going to fall apart over the long haul. Washington is a more stable team because of its defense (although the Washington defense looked very average against the Giants).
So far, it looks like the Giants will be in the cellar, and Philly and Washington could be better than average, or poor. Too small of a sample size so far.
Side note: Love seeing the Packers get the brakes beat off of them in week 1 by the Saints.
