A weekly examination of the Cowboys’ ESPN.com Power Ranking:
Preseason: 20| Last week: 15 | ESPN.com Power Ranking since 2002
But even by staying the same the Cowboys’ lead over their NFC East brethren increased, with the Philadelphia Eagles dropping to No. 23, the Washington Redskins to No. 27 and the New York Giants to No. 29.
Dan Graziano gave the Cowboys their highest ranking at No. 11, and Kevin Seifert had the lowest at No. 19, just one spot above where he had them after their 17-16 loss to the Kansas City Chiefs in Week 2. The Chiefs now check in at No. 8 in the rankings, by the way.
Up this week is a trip to San Diego and the 19th-ranked Chargers. Is it too early to think about an undefeated Peyton Manning bringing the No. 2-ranked Denver Broncos to AT&T Stadium on Oct. 6? Probably, but it will only happen if the Cowboys take care of business against San Diego.
The Cowboys certainly can't think of Manning yet, even if fans and media can. This is a team that has been 8-8 over the past two years and has to prove it can handle prosperity.
