What it means: The Seahawks drop to 3-2 overall, losing for only the second time at home in the past 19 games. Seattle had only one offensive touchdown, and that came after a muffed punt gave the Seahawks possession at the Dallas 14.
Stock watch: After five games, it's clear the Seattle pass rush isn't anywhere near as good as it was a year ago. Tony Romo had all day to throw. Yes, the Seahawks had one sack (credited to Bruce Irvin when Romo fell down) and got a bad break when defensive end Cliff Avril was held by Dallas tackle Doug Free on the TD pass by Romo at the end of the half, but that doesn't change the fact the pass rush isn't good.
Murray outruns Seattle run defense: The Seahawks had the No. 1 run defense in the league coming in, but couldn't stop the Dallas running game, including DeMarco Murray, when it counted the most. Murray rushed for 115 yards on 29 carries, including the game-winning 15-yard TD run late in the fourth quarter. Murray tied Jim Brown for the NFL record of six consecutive 100-yard games to start a season.
Harmless Harvin: The Cowboys completely shut down Percy Harvin. He had three receptions for zero yards and three carries for minus-1 yard. The Dallas defense was ready for anything the Seahawks tried at the line of scrimmage with Harvin, whether it was the jet sweep or the hitch pass. What the Seahawks needed to do was throw the ball to Harvin downfield a few times to keep the defense honest.
Lonely Lynch: Doug Hendrickson, Marshawn Lynch's agent, was not happy about the lack of carries Lynch had. In the fourth quarter, Hendrickson sent this tweet out directed at Darrell Bevell, Seattle's offensive coordinator: "Bevell know he has a running back?" Lynch had 10 carries for 61 yards, but only two carries for 8 yards in the first half.
Game ball: Mike Morgan tried to save the day on special teams, scoring one touchdown on a blocked punt and setting up another with a recovery on a muffed punt. Doug Baldwin blocked a punt in the first quarter that Morgan scooped up for a 25-yard score. Morgan also recovered the muffed punt by Dwayne Harris at the Dallas 14, which led to Seattle's only offensive TD of the game, a 9-yard run by Russell Wilson.
Injuries piling up: Cornerback Byron Maxwell suffered an ankle injury in the first half and MLB Bobby Wagner had a foot injury in the first half. Wagner, however, returned in the second half. Seattle also was playing without two starters on offense in center Max Unger and tight end Zach Miller. The good news is strong safety Kam Chancellor played the entire game after being listed as questionable with a hip strain.
What's next: The Seahawks travel to St. Louis for an NFC West battle against the Rams at 1 p.m. ET Sunday.
