Seahawks edge Chargers 16-15 on 60-yard field goal

SAN DIEGO – In the exhibition game regarded most like a dress rehearsal for the regular season, Seattle’s special teams looked pretty well-groomed for a starring role and the defense a more-than-able supporting cast.

But the offense?

For most of an eventual 16-15 victory over San Diego, the offense continued its preseason-long struggles by playing in a manner that would threaten to get the whole production shut down on opening night.

The No. 1 offense didn’t score a touchdown in six possessions, and still has not scored a touchdown in the preseason.

Seattle coach Pete Carroll admitted it didn’t look good. But he also sounded the obvious cautions that it’s just the preseason, the team isn’t throwing out its entire offense and Marshawn Lynch barely played, getting in for just the first three snaps.

“We’re all a little bit frustrated with it,’’ Carroll said. “But I’m not worried about it over the long haul.’’

Speaking of long, the Seahawks were able to leave with a collective smile on their face after winning the game on a 60-yard field goal by Steven Hauschka with 16 seconds left. That came a few minutes after Hauschka had missed a 58-yarder that was just short.

That capped a night when all of Seattle’s points were scored on special teams. Hauschka had three field goals and the other points came on a 67-yard punt return by electric rookie Tyler Lockett.

Lockett now has scored two touchdowns in three games, the other coming on a 103-yard kickoff return in the exhibition opener against Denver.

Seattle now has four touchdowns in the preseason – two on returns by Lockett, one on an interception return by linebacker Bobby Wagner, and the other coming on a TD pass from backup R.J. Archer late in the preseason opener against Denver.

Seattle went three-and-out on its first two drives, and really only moved the ball in the first half when it went to a hurry-up offense in the final minute and drove 59 yards to set up a field goal.

The No. 1 offense finished with 137 yards and eight first downs on six possessions, with Russell Wilson going 7 for 15 for 56 yards, with a long of 14 and a passer rating of 56.6.

“We need to finish drives and that’s on me,” Wilson said. “I missed a couple of throws there. But we will hit them. We believe that.”

Seattle played without left tackle Russell Okung, who had a sore shoulder earlier in the week.
