SANTA CLARA -- One of Anquan Boldin's first tasks on the 49ers is to fast-track his chemistry with Colin Kaepernick.
Boldin passed a physical Wednesday to formalize last week's trade from the Baltimore Ravens, and he recently got in touch with Kaepernick, who's in his first offseason as the 49ers' starting quarterback.
"I'm excited to get to work with him," Boldin said. "He's a special kid, smart guy, very athletic. Hopefully I can help him grow as a quarterback."
Kaepernick made only his 10th career start when the 49ers lost 34-31 in last month's Super Bowl to the Baltimore Ravens, who went ahead on the opening series with a 13-yard touchdown catch from Boldin as part of his six-catch, 104-yard effort.
Boldin emphasized that his chemistry with Ravens quarterback Joe Flacco didn't happen overnight. They started working together shortly after Boldin got traded in 2010 from the Arizona Cardinals.
"It took like a year for us to get on the same page," Boldin recalled. "Hopefully Colin and I get together and kind of shorten that window."
A week after the Super Bowl, Kaepernick started working out at CES Performance in Duluth, Ga., where he was joined by young receivers Chad Hall, Ricardo Lockette and A.J. Jenkins.
Coach Jim Harbaugh, speaking at Wednesday's NFL owners meetings, laughed off any notion Kaepernick might become complacent after his breakout season.
"Satisfied is a word that confuses him, that
Kaepernick's reputation as a fastball-throwing quarterback doesn't scare Boldin, who noted he's played with other big arms in his 10-year career.
Boldin learned of his trade upon landing in Senegal for a five-day relief mission with fellow NFL receivers Larry Fitzgerald and Roddy White. Upon his return, Boldin said he got in touch with Kaepernick to see when they could meet and start working on their "trust factor."
Boldin will likely line up as a starting wide receiver with Michael Crabtree, Kaepernick's favorite target. Mario Manningham started 10 games before a season-ending knee injury Nov. 23, and he may not be ready to start the season.
Boldin would like to be part of the 49ers longer than the one year remaining on his contract, at a salary of $6 million. But he said he's not aware of any potential extension, nor was he demanding one.
Aside from leading the Ravens in regular-season receptions (65 for 921 yards), Boldin fueled their playoff run, producing 22 receptions for 380 yards with four touchdowns, which are as many as he had in the regular season.
New 49ers kicker Phil Dawson, who left a 14-season tenure with the Cleveland Browns, has seen Boldin's capabilities the past three seasons as AFC North rivals. Boldin had three touchdowns in a 2010 Ravens victory over the Browns, and he tallied nine catches for 131 yards in a 2012 rematch.
"He knows how to rise to the challenge at that moment in the game when your team needs a play," Dawson said. "Not every guy in the league can do that. ... Anquan Boldin is the kind of guy who steps up in crunchtime and makes the big play."
Boldin's teams have reached the playoffs the past five seasons, a streak starting with the 2008 Arizona Cardinals' Super Bowl run. His arrival marks the third straight year the 49ers have signed a wide receiver coming off a Super Bowl-winning team. His predecessors were Brett Swain (Green Bay Packers) in 2011 and Manningham (New York Giants) last year.
After donning No. 4 throughout his Browns career and in college at Texas, Dawson is opting for No. 9 rather than try seizing No. 4 from his holder, Andy Lee. Dawson's one-year deal is worth $2.25 million, including a $1 million signing bonus, according to ESPN.
