Power Rankings: No. 1 Seattle Seahawks

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

Preseason: 1 | Last Week: 2 | ESPN.com Power Ranking since 2002

Not much doubt the Seattle Seahawks would return to the top spot in the Power Rankings since they soundly defeated the only team ranked ahead of them. The Seahawks earned a convincing 29-3 victory over the San Francisco 49ers on Sunday night in front a record crowd, size wise and noise wise, at CenturyLink Field.

The sellout crowd of 68,338 spectators set a Guinness Book of World Records mark for noise in an outdoor stadium at 136.6 decibels. That didn’t include the lightning strikes that delayed the game for an hour late in the first quarter.

The frenzied 12th-man fans are a huge home-field advantage for the Seahawks, but so is the best defense in the NFL. The Seahawks shut down one of the league's best offenses, keeping the 49ers out of the end zone and holding San Francisco to only 207 yards. After a career-best 412-yard effort one week earlier against Green Bay, San Francisco quarterback Colin Kaepernick was held to 127 yards passing and threw three interceptions. The Seattle defense has allowed only 10 points combined in the first two games.

The top ranking shouldn’t be in jeopardy this weekend with the lowly Jacksonville Jaguars coming to the Clink, unless the Seahawks suffer a huge letdown coming off an emotional victory and start looking ahead to the Houston Texans on the road in two weeks.
