SAN FRANCISCO — The San Francisco 49ers filled a big void in their secondary left by the departure of Dashon Goldson.
The NFC champion Niners signed safety Craig Dahl to a three-year contract Saturday, finding an apparent replacement after Goldson received a five-year deal from Tampa Bay earlier in the week.
The 27-year-old Dahl spent the past four seasons with the St. Louis Rams and had 78 tackles and an interception in 2012.
He's confident he knows the NFC West well enough to fit right in as a regular for the two-time defending division champions.
"Not the enemy anymore," Dahl said on a conference call. "It's a program I'm really familiar with, players and coaches I'm familiar with how they operate and the basis of what their team fundamentals are. ... The mentality of the division has changed, teams are a lot more aggressive on defense and it's turning out a lot better football teams than it has in the past."
