The upside: Even the worst defeats tend to feature a bright spot or two.
Rookie James Carpenter played better in his second NFL start despite switching positions on the offensive line. Carpenter opened the season at left guard. He made it through a tough situation at right tackle Sunday.
Left guard Robert Gallery returned from injury and made it through the game.
The team still hopes to get receiver Sidney Rice back from injury this week despite a torn labrum in Rice's shoulder.
Rookie receiver Kris Durham caught three passes and generally played well under the circumstances. Second-year receiver Golden Tate made a difficult catch along the sideline for a short gain on a pass that almost appeared to be thrown away.
Seattle made it through the game without any new injuries of significance.
The Seahawks stopped the Steelers four times after Pittsburgh had a first-and-goal from the 1 on its opening possession. The play went under review, as the case had been on Ben Roethlisberger's disputed 1-yard run in Super Bowl XL, but this time there was no controversial reversal in the Steelers' favor.
Looking ahead: The Seahawks open their NFC West schedule at home against the Arizona Cardinals.
