The cornerback position is a constant source of stress and doubt when it comes to the San Francisco 49ers. Ever since Nate Clements, the team has jumped from risky free agent signing to risky free agent signing and ... for the most part, they have turned out just fine. Sometimes better than others, and sometimes they've hung on just barely, but somehow the 49ers have generally ended up with a fairly decent secondary, and not just because of the talent at safety.
Of course, things weren't perfect. Last season, the wheels started to come off a little as the 49ers suffered from the loss of Chris Culliver and Perrish Cox in free agency.
