Were the Seattle Seahawks suffering a Super Bowl hangover? Their season appeared to be slipping away before things slowly began to change.

The Seahawks started the season 3-3, but they enter the game against the Eagles on Sunday with an 8-4 mark and renewed confidence.

So what changed?

"I think just having to step up, making sure that everybody was on the same page and just continued to work hard," third-year quarterback Russell Wilson said Wednesday in a conference call with Philadelphia media. "We had one of the toughest schedules; that is no excuse."

Two of the wins during that time were over prime Super Bowl contenders Green Bay and Denver.

Actually, a major difference is that the Seahawks got healthier on defense, especially with the return of linebacker Bobby Wagner. With Wagner back in the lineup after a toe injury, the Seahawks have earned consecutive 19-3 wins over Arizona and San Francisco.

Wilson, who had a passer rating of 99 or higher in five of the first six games before going into a three-game slump, has thrown 15 touchdown passes and five interceptions. With a suspect receiving corps, he is running more than ever, with a career-high 679 yards on 91 carries and four touchdowns.

"You have to keep playing championship football every week," Wilson said. "That is what we look forward to and that is what we have been able to do the last couple of weeks."
