Richard Sherman celebrated by dancing with cheerleaders, Marshawn Lynch cut, plowed and strolled his way to three touchdowns, and Pete Carroll got a rousing birthday gift. The highly anticipated NFC West showdown between the Seattle Seahawks and San Francisco 49ers was a one-sided rout. Lynch scored on runs of 14 and 2 yards, and added a 7-yard touchdown reception in the second half, Seattle flustered Colin Kaepernick into his worst passing game as a starter, and the Seahawks dominated in a 29-3 win Sunday night.
