"I think we're the two teams that everybody was looking at from the beginning," San Francisco quarterback Colin Kaepernick told reporters during a press conference. "It's going to be a knockdown, drag-out game. We're ready to go."

This stadium has set the record for noise inside an American stadium.

"It's a big deal to play here," Seahawks cornerback Richard Sherman told the team's official website. "We've earned that right to play them at home, to be on our home field in front of our fans."

With the "12th Man" crowd there to lend support, the Seahawks have won six straight home playoff games, highlighted by a 34-14 victory over Carolina in the NFC championship game during the 2005 season. The noise level in the stadium even produced a small earthquake during last Saturday's 23-15 win over New Orleans, according to ESPN.com.

"We understand that we have to go up there in a hostile environment with a really good football team and do what a lot of people probably aren't going to pick us to do," San Francisco safety Donte Whitner said. "That's OK with us. We understand what we have to do."
