Power Rankings: No. 8 San Francisco

A weekly examination of the 49ers' ESPN.com Power Ranking:

Preseason ranking: 3 | Last Week: 10 | ESPN.com Power Ranking since 2002

The San Francisco 49ers’ short journey out of single-digit rankings is over after a 35-11 win at St. Louis in Week 4. Last week, the 49ers fell to No. 10 after dropping to 1-2. It was the team’s lowest ranking since Week 5 of 2011. The 49ers were never ranked lower than No. 5 last season.

Now, they appear to be back on the right track. The voting panel clearly respects and believes in San Francisco. The 49ers are the highest-ranked 2-2 team in the league. They are also ranked higher than Chicago, Detroit and Tennessee. Those teams are all 3-1.

A win over visiting Houston, ranked No. 15, should keep the 49ers pointing upward in Week 6.
