Although both teams have clinched a playoff berth, the winner will be crowned champions of the NFC East and earn the reward of a home playoff game.
If Philadelphia wins, it will earn the No. 2 seed in the NFC and a first-round bye. Dallas could get that, too, with help.
Two weeks ago, Dallas was coming off consecutive losses and could have easily folded, especially going to New Orleans to play the 13-0 Saints. But the Cowboys knocked off the Saints, then shut out the Redskins in Washington. The surge probably saved Wade Phillips' job.
The Eagles, 5-4 in mid-November and coming off consecutive defeats, have won six straight, putting themselves in position to become the betting-line favorites to represent the NFC in the Super Bowl. Quarterback Donovan McNabb has the Eagles averaging 31.2 points during the winning streak.
