After their second straight last-second loss, the Dallas Cowboys have turned what could have been an overwhelming two-game lead in the NFC East into a dog-fight that will probably go down to the last week of the season.
As a result, the Cowboys have slipped from No. 10 to No. 14 in SBNation's latest NFL Power Rankings:
14. Dallas Cowboys (7-6, LW: 10): The Cowboys have had a few chances to take a commanding lead in the NFC East but two losses in a row now have them tied with the Giants for the division lead.
But perhaps more devastating than the blown game to the New York Giants was the loss of rookie RB DeMarco Murray for the year.
Murray's emergence halfway through the season had changed the complexion of the team, as he set a Dallas rookie rushing record with 164 carriers for 897 yards in 7 games.
Now, the Cowboys are down to only one healthy running back, the perennially injured Felix Jones, a huge problem for a team that's already struggled to hold fourth-quarter leads this season.
