The upside: Even the worst defeats tend to feature a bright spot or two.
The Seahawks had a chance to win a game they played without starters at quarterback, running back, center and tight end.
Red Bryant blocked two field-goal attempts.
Leon Washington carried seven times for 56 yards. He also broke an 81-yard punt return for a touchdown, negated by a penalty.
Seattle's defense held the Browns to six points and 298 yards even though its offense held the ball for only 17 minutes.
David Hawthorne, slowed by a knee injury at times this season, looked healthy. He picked off a pass at a critical time and finished with 11 tackles, plus a sack.
Strong safety Kam Chancellor repeatedly made big hits and finished with eight tackles, plus a sack.
Cornerbacks Roy Lewis and Byron Maxwell could return this week after missing time with injuries. Lewis has been on the physically unable to perform list. Maxwell, who enjoyed a strong rookie camp, has been recovering from a high-ankle sprain. Their returns could help the team deal with Walter Thurmond's season-ending injury.
Looking ahead: The Seahawks are home against Cincinnati in Week 8.
