Power Rankings: No. 15 Dallas Cowboys

A weekly examination of the Cowboys' ESPN.com Power Ranking:

Preseason: 20 | Last Week: 11 | ESPN.com Power Ranking since 2002

The Dallas Cowboys tumbled in the ESPN.com Power Rankings to No. 15 after their embarrassing 45-28 loss to the Chicago Bears on ESPN’s "Monday Night Football."

It is a wonder they did not slip further. And their main competition in the NFC East, the Philadelphia Eagles, climbed into the top 10 at No. 9 thanks to their fifth straight win. At this point, you have to wonder whether the Week 17 finale against the Eagles at AT&T Stadium will be for anything more than pride.

A week ago, Mike Sando and Kevin Seifert were the biggest believers in the Cowboys, moving them up to No. 9. This week they have them at No. 16 and Jamison Hensley gave the Cowboys the lowest grade, dropping them to No. 17.

The defense continues to be a mess and might not have Sean Lee or Bruce Carter this week. The offense has to play near perfectly to have a chance, and it has been close to perfect just once this year against the Denver Broncos.

If there is a good note for the Cowboys, it is that the No. 18 Green Bay Packers visit AT&T Stadium this week.

Wait, Aaron Rodgers might play? Never mind.
