The 2004Seattle Seahawks season was the team's 29th season with the National Football League. Seahawks Stadium was renamed Qwest Field when Qwest bought the naming rights on June 2, 2004. Finishing the season at 9-7, the Seahawks were unable to replicate the year they had prior. In the Wildcard round, the Seahawks met the defunct St. Louis Rams (now in Los Angeles), who swept them 2-0 in the regular season. Seattle looked to avenge on their two losses, but it was too late as Matt Hasselbeck's game-tying drive to Bobby Engram was incomplete, leading Hasselbeck to his knees and punch the turf in frustration. The Seahawks would go on to lose 27-20. The Rams, despite a mediocre 8-8 record, advanced to the Divisional Round the following week, only to lose to Michael Vick's Atlanta Falcons in a 47-17 blowout.
The Seahawks won for only the seventh time in their last eighteen road games, holding Aaron Brooks to one touchdown while forcing two New Orleans fumbles.
