Says USA Today:

The Cowboys are currently 6-6, with games left against Chicago, the Rams, Philly and Washington.

The Eagles are 5-7, with the Giants, Washington, Dallas and another game against the Giants still to come.

In the best-case scenario, Dallas would claim the NFC East with 10 wins or Philly with nine wins.

Worst-case, and this is not so far-fetched, the NFC East winner finishes below .500.

Either way, they still get a top-four seed and host the wild card game:
