It was one of the biggest, and perhaps the most quickly forgotten, interceptions in NFL playoff history.

When Seattle's Richard Sherman tipped away a pass intended for 49ers receiver Michael Crabtree in the NFC Championship game, linebacker Malcolm Smith caught the ball to complete a play that sent the Seahawks to the Super Bowl.

But Smith's heads-up effort instantly became an afterthought when Sherman's emotional postgame outburst made the cornerback one of the Super Bowl's main storylines.

That's fine with the low-key Smith.

"I'm sure when I get older, I'll think about it," he said of the interception. "To me, it really was just a play."

Smith is also understated -- but excited -- about a chance to make history Sunday against the Denver Broncos.

If the Seahawks win, Smith and his older brother Steve would join six brother combinations that have won Super Bowl titles as players.

"I would love to join that club," said Steve, a receiver who helped the New York Giants win Super Bowl XLII in the 2007 season. "That would be a cool honor."

Peyton and Eli Manning, Bubba and Tody Smith, Matt and Chris Bahr, Jim and Keith Fahnhorst, Chris and Ma'ake Kemoeatu and Darren and Jamie Sharper are brothers who played for Super Bowl winners.

In February 2008, Malcolm Smith was a spectator in Glendale, Ariz., and saw Steve help the Giants defeat the New England Patriots. Steve caught five passes for 50 yards, including a key third-down reception that set up the winning touchdown.

"I just remember being in the stands, and after they won, getting onto the field and seeing how happy they were," Malcolm said.

Coaching Manning: The first question Wednesday to Greg Knapp was a simple one. But it had to be asked nonetheless.

Do you coach Peyton Manning at this point?

"No doubt you do," the Denver quarterbacks coach replied.

Though he's only in his first year with the Broncos, Knapp has faced this challenge before -- striking a delicate teacher-pupil balance with a future Hall of Famer. Early in his coaching career, he was "fortunate" to have a veteran Steve Young as his quarterback with the 49ers. And even though Young already was a Super Bowl champion, the quarterback still demanded to be coached.

Shortly after Knapp joined the 49ers' coaching staff, Young pulled Knapp aside and said: "Hey, you need to coach me. You can't just sit back and watch."

"I learned then -- the great ones, that are truly great, want to be coached," Knapp said. "And they want to be coached hard. So you do want to coach them."

That's why he had no doubt Manning would expect the same.

Manning, the league's ultimate perfectionist, still seeks counsel. Oftentimes before the quarterback goes to bed, he fires off a text message to Knapp that's geared toward the next day's prep work.

"Hey, make sure you stay on my footwork."

"Hey, make sure you stay on my pre-snap reads."

"He's a strong self-evaluator of how his performance needs to be," Knapp said. "And that's what's enjoyable. Because he does want to be on top of his game every day at practice, not just on Sunday."

Lynch mostly quiet: Seahawks running back Marshawn Lynch abruptly ended his media availability again, walking away from reporters while escorted by a member of the New Jersey State Police after about 7 minutes in which he answered just a few questions.

Lynch, who created a stir Tuesday by talking for only 61/2 minutes, writhed in his seat and leaned his head back at times. A few dozen reporters tried to ask questions during the players' 45-minute availability at the team hotel.

"I really don't have too much to say, boss," Lynch said in a tone barely above a whisper. "I really don't. I appreciate it, but I don't get it. I'm just here so I won't get fined, boss. That's the only reason I'm here."

Earlier this month, Lynch was fined $50,000 for not cooperating with the Seattle media. The NFL put that fine on hold, saying it would be rescinded if he complied with media obligations.

Bills: Jim Hostler was hired as a senior offensive assistant coach. Hostler has 14 years of NFL coaching experience, including the past six as Baltimore's receivers coach. He spent three seasons with the 49ers, including 2007 as offensive coordinator.
