The Chargers have signed 29-year old cornerback Donald Strickland to a 2-year deal.  Strickland played in 9 games for the Chargers last season in which he made 26 tackles, 1 tackle for a loss, he had 2 sacks, forced 1 fumble and he defensed 2 passes.  Strickland has now played in 58 games in his NFL career in which he has made 188 tackles, defensed 18 passes, forced 4 fumbles, intercepted 2 passes and he has 2 sacks.  Strickland projects to be a nickel or dime back and special teams player but don’t be surprised if he wins a starting job in 2010.
