The 49ers somehow played an entire season last year and intercepted only 2 passes, which defies belief. That's 5 fewer than the 2nd-worst teams in that area. They say they're looking for a "starting-caliber safety" in free agency, which you'd think goes without saying. The good news for San Francisco, and the other teams in need of a starter or two at the position, is there are a lot of good ones available.

You might think running back is the least-respected position in the NFL, but safeties are up there (down there) too. The Ravens released Eric Weddle (pictured) yesterday, despite him being one of the league's best at the position. In fact, both Pro Bowl starters, Weddle and Earl Thomas, are available in free agency. And so are a lot of the league's most productive tacklers at the position.

Of all the players who have ranked in the top 40 in tackles among defensive backs in any of the last three seasons, a significant number (17) are currently available in free agency. That includes six of last season's top producers. In the table, 2018 starters hitting the market as free agents are in bold.

San Francisco should be able to find a quality option or two on this list. So should teams like the Ravens, who deemed Weddle too expensive.
