Analysis: The 30-year-old Costanzo played 16 games for Chicago last season and finished with nine tackles and a forced fumble while also contributing on special teams. San Francisco will count on the depth at linebacker that Costanzo helps provide given All-Pro NaVorro Bowman is recovering from a left knee injury sustained in the NFC championship game. Bowman could miss at least half the season.
