Brian, as much as I hate to say it as a Cowboys Fan, the NFC East is now the Eagles to lose. 

1. The Redskins can't catch them b/c they are 3 games behind and have lost to them twice, which means they have to finish AHEAD of the Eagles to make the playoffs. Not going to happen
2. The Giants are done
3. The Cowboys are the only ones with a chance but - being 3 games behind - they will have to beat the Eagles in both games to close the gap to 1. At that point, anything can happen but beating this team twice is a tall order.

Conclusion? NFC East is Eagles to lose now.
