Defensive line issues have led to opposing teams rushing for 142.3 yards and 4.5 yards per carry so far this season against the Chargers.  Linebacker Stephen Cooper has been really busy for the Chargers so far this year.  He has 28 tackles (leads the Chargers), 2 tackles for a loss, he has forced a fumble and defensed two passes.  It’s too bad that the Chargers don’t have a better D-Line to protect Cooper or he would probably have many more tackles this season.
