SANTA CLARA — With so much talent returning on defense, several San Francisco 49ers players have taken advantage of an intriguing new resource in training camp.
That being Anquan Boldin.
The versatile wide receiver said Friday that curiosity has simmered from his defensive teammates about how opponents scheme against the unit since he joined the 49ers this offseason. And nobody in practice might know better than Boldin, who caught six passes for 104 yards and a touchdown to help the Baltimore Ravens beat San Francisco 34-31 in the Super Bowl.
“A lot of guys came up to me and asked me, 'What did the scouting report have on it? What did it say?”' Boldin said. “Things like that. I've had a chance to communicate that to guys.”
While he's not going to make those schemes public knowledge, Boldin has passed along that information to teammates while doing his own job catching passes from Colin Kaepernick. Picking Boldin's brain for ideas is just one of many ways the 49ers defense — among the NFL's best the past two seasons — is trying to improve from within.
After all, San Francisco has almost everybody back on defense again. That continuity helps build upon past success, but it also allows little opportunities to improve — other than from within.
“When you've done it so many times and you're OK at a lot of positions, we try to find little nitpicky things to get better on,” cornerback Carlos Rogers said.
The departures of All-Pro safety Dashon Goldson and nose tackle Isaac Sopoaga left the most glaring vacancies to fill among the starting unit. At the other nine positions, San Francisco still seems stacked.
The 49ers ranked third in total defense (294.4 yards), fourth in yards rushing allowed (94.2) and fourth in yards passing allowed per game (200.2) last season. The unit still had flaws, though, most notably going from No. 1 in takeaways (38) two years ago to No. 6 (25) in the league last season.
