The Oakland Raiders have signed 26-year old offensive tackle Khalif Barnes to a 1-year deal.  Barnes is a big man at 6’5″, 325 pounds and he should be able to offer JaMarcus Russell with improved pass protection in 2009.  Barnes played in 16 games (all starts) for the Jaguars last season.  He has now played in 60 games (57 starts) in his 4-year NFL career.  This was a solid move for the Raiders who definately needed some offensive line help.
