RENTON, Wash. – Given a primetime stage, Seattle again excelled, getting the upper hand in the NFC West on Sunday night as the Seahawks routed San Francisco, 29-3.

The highly awaited showdown between division foes was completely one-sided in favor of Seattle. Marshawn Lynch’s running and a nasty defensive effort that made life miserable for Colin Kaepernick, Frank Gore, Anquan Boldin and the rest of San Francisco’s offense.

Seattle (2-0) has outscored San Francisco 71-16 in the past two meetings — both coming at noisy CenturyLink Field — and are in position to hold an advantage on its division rivals until they meet again in December.

The lasting image from Seattle’s defensive line came in the third quarter when Red Bryant knocked All-Pro guard Mike Iupati on his backside and chased Kaepernick out of the pocket.

Not only does Seattle have the fiercest home field advantage in football, they might be the deepest team in the NFL.

That depth will be put to the test again in the coming weeks with starting left tackle Russell Okung expected to miss at least Sunday’s game against Jacksonville after suffering a toe injury against the 49ers.

Coach Pete Carroll would not go into specifics of Okung’s injury, just saying it was unlikely he’d be able to play Sunday.

“There are some options that we’ll deal with here to try and figure it out,” Carroll said.
