The 49ers have signed 33-year old offensive tackle Barry Sims to a 2-year contract.  The 6′5″, 300 pound Sims will likely be a starter for the Niners in 2008.  He played in 16 games for the Raiders last season (all starts).  Sims has now played 9 seasons in the NFL covering 136 games (119 starts) in his NFL career.  This was a good move for the 49ers.
