The Eagles may have the worst record in the NFC East right now but that will only last until wk 8. The Eagles don't lose after the bye, so they beat Cowboys (in Philly). I expect the Redskins to lose to CAR and BUF in the meantime also. Now expecting Dallas to beat the Rams next week, it makes the Cowboys, Redskins, and Eagles all at 3-4.
If you aren't understanding the ranking going into wk 9...
The 2nd half of the season is rough for the Redskins and Giants, so then its a race to the finish between the Eagles and Cowboys. And the Eagles come out on top because Romo can't win in December. lol.
