RENTON, Wash. -- With the Seattle Seahawks looking to avoid their fifth loss of the season Thursday night against the San Francisco 49ers, cornerback Richard Sherman was asked how big of a hole his team is currently in.

"The same size it always is," Sherman said calmly. "Not anything to be concerned about on our end. I think we're a hard team to rattle, a hard team to get down."

"Not anything to be concerned about on our end. I think we're a hard team to rattle, a hard team to get down."

That's the theme surrounding the Seahawks this week. They've blown fourth-quarter leads in all of their four losses. In the past three games, Seattle has been outscored 40-3 in the fourth quarter and overtime.

But the core of the roster is still comprised of players who led the Seahawks to Super Bowl appearances in back-to-back years. And they seem convinced they're about to turn their season around.

"I think sometimes these moments kind of help you improve as a team, and I think we appreciate that," Sherman said. "We appreciate how tough it is this year. We're in a lot of these games. It'd be a different story if we were getting blown out by 40 points every week, and there's no way to fix it. But there's one mistake, one play here or there that guys just need to clean up or correct, and we're right on it."

Added safety Earl Thomas: "This is great, really. It's a part of the story. We're going to outlast this. This is why we're in this position in the first place. This is why we're the best. These situations, they're not going to break us."

With a loss Thursday, the Seahawks would be in unfamiliar territory: sole possession of last place in the NFC West.

Sherman was asked why fans shouldn't panic about the team's 2-4 start.

"Because we know who we are," he said. "Obviously they don't if they're concerned. Sometimes you've got to treat the fans and some of the critics just the same because they don't know any better. They see what they see. They hear what they hear, and sometimes it's easy to pass judgment.

"It's no problem with being concerned and things like that, but if all is lost for them, they're probably the only ones giving up faith. The guys in this building feel the same way as they always have."
