RENTON, Wash. - Even with their playoffs hopes now gone, Pete Carroll doesn't intend on using the final week of the regular season as a trial to see what Seattle might have for next year.

The Seahawks' late-season run that got them back into the playoff conversation was centered largely on young players with a future in Seattle anyway.

"I don't think we're changing anything in that regard. We're going to try to win the football game," Carroll said on Monday. "To look at something for the future is not on our minds at all. We want to come back and play another good game of football."

Seattle's slim playoff hopes were dashed on Saturday in a 19-17 loss to NFC West champion San Francisco.

The Seahawks (7-8) were going to need plenty of help from others to even have postseason hopes going into the final week, but David Akers' fourth field goal of the game gave the 49ers the lead with 2:57 left and Seattle couldn't answer.

The Seahawks' best chance ended when quarterback Tarvaris Jackson was stripped from behind by San Francisco linebacker Larry Grant with just over a minute remaining and Donte Whitner fell on the loose ball at the 49ers' 36.

It was the second time in the past month Seattle lost at home after leading in the fourth quarter - both losses big reasons why the Seahawks' playoff hopes are finished heading into the final week of the season.

"We had plenty of opportunities to win the game, but we didn't make those plays when it came down to it, and obviously we have to make those plays," Jackson said after the loss. "We have to be able to grow and mature and make those plays when it really counts."

Within the loss, Seattle continued the offensive progress centered on the run game that's been clearly apparent during the latter half of the regular season.

The Seahawks became the first team this season to score a touchdown rushing on the 49ers defense when Marshawn Lynch scooted around the left end and scored on a 4-yard run with 6:41 remaining that gave Seattle a 17-16 lead.

On Seattle's next-to-last drive - that ended with Jackson's fumble - Lynch became the first 100-yard rusher against San Francisco since November 2009 when Ryan Grant topped the 100-mark for Green Bay. Lynch's 107 yards on 21 carries broke a 36-game streak of San Francisco not allowing anyone to top the century mark.

While it came in a loss, Carroll felt that might have been the most impressive performance by Seattle's run game during its rediscovery in the second half of the season.

"I think it's something that we do take some pride in because they are very, very well-schemed and very well-equipped and they take great pride in it as well. Anybody that goes for a couple years without giving up a 100-yard rusher and stuff - that's a good, talented group of people," Carroll said.

"So I don't care about those accomplishments so much, but I like the fact that we were consistently able to get some movement."

Seattle's ability to run on the 49ers gained most of the headlines, but San Francisco's run game was even more successful against the Seahawks.

The 49ers' 178 yards rushing were the most allowed by the Seahawks this season and the fifth straight week of a team topping 100 yards on the ground versus Seattle.

Carroll expected that Frank Gore would have a good game and he did, running for 83 yards and a 4-yard touchdown on the first drive of the second half.

What Seattle didn't expect was backup Kendall Hunter to run for a season-high 73 yards on just 12 carries and churn off chunks of yardage especially out of the shotgun formation. Before Saturday, Hunter had topped 40 yards rushing only once this season.

"I think his 70 yards were yards we didn't want to give up. If we gave up 80 yards or 90 yards to (Frank) Gore we would say that's a pretty solid game against them, but him getting to 70 or whatever it was made a really big difference," Carroll said.

Along with Hunter's contribution, Carroll pointed out the 22 yards that Alex Smith ran for as being critical.

Smith had a 10-yard, third-down scramble that setup a fourth-and-2 on the first drive of the second half. Smith then bought time on the fourth-down play and found Vernon Davis for 16 yards, and three plays later Gore scored to pull San Francisco even at 10-10.

On the 49ers next drive, Smith's 12-yard scramble on third down kept alive a drive that concluded with David Akers' 29-yard field goal that gave San Francisco the lead.

"Alex did a nice job. I really thought that he was the difference in the game for them," Carroll said.
