A weekly examination of the Chargers' ESPN.com Power Ranking:
Preseason: 23 | Last Week: 15 | ESPN.com Power Ranking since 2002
The San Diego Chargers dropped two more spots to No. 17 in this week's Power Rankings. At 4-5, the Chargers have their first two-game losing streak this season and now face two tough games on the road, including a cross-country trek Sunday at Miami and at AFC West division rival Kansas City the following week.
Despite the disappointing loss to Denver over the weekend, the Chargers have some positives to build on this week. San Diego's defense held Denver's high-scoring offense scoreless for most of the second half, while Philip Rivers led the offense on two touchdown drives that allowed the Chargers to close within a score. And middle linebacker Donald Butler provided a spark defensively in his first game back from a groin injury.
The Chargers have defeated Miami the past two times the teams have met and are 2-1 in the Eastern time zone this season (wins over Philadelphia and Jacksonville, a loss to Washington). However, the last time San Diego played at Miami, the Chargers suffered a 17-10 loss to the Dolphins in 2008.
