49ers free-agent report: Kassim Osgood

The San Francisco 49ers have 14 potential unrestricted free agents who would hit the market when the new league year begins on March 10. We continue our countdown with a receiver who has excelled on special teams and whose roster spot grew more valuable by the week last season.

WR Kassim Osgood

Undrafted out of San Diego State, Osgood made his NFL debut in 2003 and became a three-time Pro Bowler as a special teamer with the San Diego Chargers. After seven years with the Chargers, he moved on to the Jacksonville Jaguars for two years and the Detroit Lions for one before coming to the 49ers in 2013. He has appeared in 179 games in his career and has caught 45 passes (one since 2012), for 766 yards and five touchdowns (one since 2004). His first career TD catch came on a Doug Flutie pass.

49ers career: Osgood was named the 49ers' special teams blue collar player of the year after racking up seven special teams tackles last season in 13 games. Twice he was cut by the 49ers to make roster room, only to be re-signed later. His season came to an end, though, when he was placed on Injured Reserve with a hand issue in December.

Argument for keeping Osgood: He has been the 49ers’ best special teams player the past two years, and no price can really be put on such a key description, even if special teams ace is more ceremontal title than actual position. His leadership on special teams would be integral for new coach Jim Tomsula.

Argument for letting Osgood walk: He will be 35 in May, and as valuable as his contributions have been the past two seasons, he is coming off an injury. Plus, with a roster in need of a fresh scrubbing, the 49ers could use younger, fresher faces on special teams, and Osgood has only caught one pass in 27 games with the 49ers.

A bold prediction: Osgood takes his special teams talents up I-880 from Santa Clara to Oakland to join his old special teams coach with the Raiders in Brad Seely.
