Power Rankings: No. 1 Denver Broncos

A weekly examination of the Broncos’ ESPN.com Power Ranking:

Preseason: 3 | Last week: 1 | ESPN.com Power Ranking since 2002

After becoming just the fourth team in league history to score at least 50 points in back-to-back games, the Denver Broncos held down the top spot in ESPN.com’s Power Rankings with a 51-48 victory in Dallas.

Sure, the Broncos surrendered 506 yards passing to Cowboys quarterback Tony Romo. And yes, three defensive starters left the game with injuries -- defensive end Robert Ayers (left shoulder), cornerback Chris Harris (concussion) and linebacker Wesley Woodyard (neck) -- putting them down five defensive players, with Von Miller and the injured Champ Bailey included. But the Broncos' offense just keeps barreling down the tracks.

Their 230 points are the most after five games in league history, quarterback Peyton Manning has 20 touchdown passes, also most in league history after five games, and the Broncos have won 16 regular-season games in a row.

But with the offensively challenged Jaguars on the docket this week, coach John Fox is having none of it. When asked about the potential for overconfidence he said, “One thing I learned is when you fall asleep at the wheel, you wreck."
