Before Cory Redding signed with the Ravens in 2010, he spent a season lining up at defensive end for the Seahawks. Redding racked up a pair of sacks in three starts for Seattle in 2009 and played in 15 games.

Redding, who spent his first six seasons in Detroit, returns to Seattle on Sunday for the first time since.

“It’s going to be a great atmosphere,” Redding said. “I still know a few guys on the team and there are a lot of good people still with the organization, so it will be good to see them and also good to compete against them. And playing on the opposite side and getting booed by the fans and all that good stuff.”

Redding says the home-field advantage at CenturyLink Field, formerly Qwest Field, is legit as advertised because the off-the-charts crowd noise benefits the Seahawks by blaring opposing offenses out of sync.

“The whole 12th man will be in effect,” he said. “We’re going to have to battle the fans along with the team.”
