NFC West Week 1 decisive moment

Three years had passed since Marcus Trufant last returned an interception for a touchdown.

The Seattle Seahawks cornerback was a Pro Bowl player back then. He played at that level Sunday and his 32-yard interception return for a touchdown turned a potentially tenuous Seattle lead into a rout during the Seahawks' 31-6 victory over the favored San Francisco 49ers.

The score was 14-6 when 49ers quarterback Alex Smith dropped back to pass on third-and-8 during the opening drive of the second half. A touchdown drive could have returned momentum to the 49ers. Instead, Trufant lined up tight against receiver Josh Morgan, then peeled off to intercept a pass intended for Michael Crabtree. The pass was thrown inaccurately, 49ers coach Mike Singletary said. Trufant tracked the ball right away and quickly transitioned to offense, stepping over Crabtree and running up the left sideline for the score.

The Seahawks have told their corners to play more aggressively this season.

"Yeah, plays are going to come to you when you’re flying around," Trufant told reporters after the game.
