SANTA CLARA, Calif. — Trent Baalke and Jim Harbaugh have a man in mind for the 30th pick in Thursday's NFL draft, if the player is still around at that spot for San Francisco. And if the 49ers don't jump on a chance to move up to land someone they believe could help right away as the reigning NFC West champions look to make another Super Bowl push in 2012.

SANTA CLARA, Calif. — Trent Baalke and Jim Harbaugh have a man in mind for the 30th pick in Thursday's NFL draft, if the player is still around at that spot for San Francisco. And if the 49ers don't jump on a chance to move up to land someone they believe could help right away as the reigning NFC West champions look to make another Super Bowl push in 2012.

They might just trade down, too.

Baalke has been right on in running the past two drafts, selecting several players who contributed immediately — from offensive linemen Anthony Davis and Mike Iupati two years ago to 2011 rookie linebacker Aldon Smith, who wound up with 14 sacks.

While it has always been the general manager's approach to snag the best possible player available, this draft is slightly different for the 49ers: San Francisco is set just about everywhere on the roster.

The Niners also are picking much lower, and there's not a major need at any one spot.

"I think you always try to go through the offseason and take care of as many of the needs as possible," Baalke said. "That's part of free agency, addressing needs. As your team gets deeper, you hope to have fewer needs, which should allow you to concentrate on the best-player-available formula."

San Francisco returns all 11 defensive starters on coordinator Vic Fangio's unit, which was No. 1 at stopping the run last season. Baalke already brought back cornerback Carlos Rogers and franchise safety Dashon Goldson after the two shared the team lead with six interceptions apiece in 2011.

On the offensive side, quarterback Alex Smith reached a new three-year deal last month, and Baalke also signed wideouts Randy Moss after he spent a year away from football and recent Giants Super Bowl star Mario Manningham. They are expected to boost the unit after the Niners' receivers managed only just one catch for 3 yards in a 20-17 loss in the NFC championship game to New York at Candlestick Park on Jan. 22.

This is a far cry from a year ago, when eventual NFL Coach of the Year Jim Harbaugh could do little more than plan as he waited out the lockout to build a team for his first season.

The 49ers chose Aldon Smith with the seventh overall pick in last year's draft, and he wasted no time becoming a hit for his big hits. A year earlier, Baalke selected right tackle Davis at No. 11 and then left guard Iupati six spots later. Both started every game as rookies.

Baalke had a good feeling about Aldon Smith within the first five minutes of watching him on film.

"I'm a big believer in the book 'Blink,'" the GM said. "I think your instincts, when you go in and look at a player, what you see initially in that first five to 10 minutes, what your feelings are, if we were to go back and take a look at it, generally speaking you were right in that first five to 10 minutes. ... I think a lot of times you spend too much time evaluating certain players and you either make them better than what they are or you make them worse than what they were. The initial reaction is usually the correct one."
