SANTA CLARA, Calif. (AP) — Colin Kaepernick and the San Francisco 49ers have conquered the bitter cold of Green Bay and the travails of a cross-country flight to Carolina.
Now they face their toughest test yet to get back to the Super Bowl: the deafening noise of Seattle's 12th man home crowd and that swarming Seahawks defense that thoroughly shut down the reigning NFC champion Niners in Week 2.
"Our team has been in a lot of good primers, been through a lot of situations, been through tough environments, whether it be weather or opposing stadiums," coach Jim Harbaugh said Monday. "This team has been in a lot of situations. Been everywhere, man. Just like something from a Johnny Cash song, 'We've been everywhere man.'"
In what has emerged as arguably the NFL's best rivalry, San Francisco is on an impressive roll riding an eight-game winning streak as it returns to the Pacific Northwest for Sunday's NFC title game — the 49ers' third in as many years.
It's the trip everyone has envisioned for months now since it became clear Seattle would win the NFC West and secure the No. 1 seed.
"Long story short: They know us, we know them," linebacker NaVorro Bowman said. "We got to go there. We all know the history. But this is the Super Bowl. Everything is on the line. That says it all. We're ready. That's all it comes down to."
The 49ers (14-4) have committed seven turnovers and been outscored 71-16 in their last two trips to Seattle, including an embarrassing 29-3 defeat in September.
The memory of those visits stings.
Yet a lot has changed in four months since San Francisco last traveled some 800 miles up the Pacific Coast to face its archrival, such as the 49ers' 19-17 victory against the Seahawks last month at Candlestick Park. That game showed this team it can go back to Seattle this time and leave with a different result even if it thunders and rains all afternoon.
"Oh, man, this is everything. We've worked hard," linebacker Ahmad Brooks said. "Now we need to capitalize on what we've been doing all year."
Be prepared from some high-octane trash talking from both sides — and even from that raucous, tremor-causing home crowd. Seattle's secondary loves to chirp, and 49ers wideout Anquan Boldin has been talking after the play at any chance in recent weeks.
