Stop the run. For all the criticism the Raiders have gotten for some of their off-season moves, their linebacking corps is one of their stronger suits. They’ll need veterans Miles Burris and Nick Roach to lead promising rookie Sio Moore to close down running lanes and hold opposing offenses to fewer than three yards a carry. Denver running backs Ronnie Hillman and Knowshon Moreno are potent threats, running for 330 and 525 yards last season, respectively. Ryan Mathews had 707 yards for the Chargers.
