(Delanie) Walker takes obvious pride in his aggressive mentality on special teams -- he joked that he hoped the Niners would make him a two-way player with the added duties of linebacker or safety.
After Walker had four special-teams tackles Sunday -- tied for the fourth-most by a 49ers player since 1990 -- Harbaugh said Walker "was an animal out there on kickoff coverage."
Today, Walker got more specific about his non-human, special-teams mentality.
"It's like a shark," Walker said. "I smell blood. That's the person holding the ball and I'm going to attack first and I'm going to let everyone else eat after I eat."
* Walker said Ginn was telling his coverage units that he just needed a "couple more blocks" and he would score Sunday before his 102-yard kickoff return and 55-yard punt return for touchdowns. Not that that's particularly unusual coming from Ginn.
"He says it all the time," Walker said. "Right when we get in our huddle when we say the play, (he says) 'Hey, one block and I'm going to do the rest and ya'll can look at me score.' And that's what we did. We watched that man because we can't catch up to him. We just watch him run into the end zone."
* The Niners' emphasis on special-teams is clear under Brad Seely. Similar to his other stops in his 22-year career as a special-teams coach, Seely has a core group of largely special-teams-only players that includes Blake Costanzo, C.J. Spillman, Tavares Gooden and rookie Colin Jones.
"We look at special teams as a starting unit," Walker said. "If you're on special teams, you start. We start the game. We finish the game. And our special teams coach, man, he's really on us. We practice like an hour on special teams and that's really unusual. And it showed. It showed out there yesterday what the special teams is capable of doing when you work hard."
