Chargers coach Mike McCoy said in an interview with CBSSports.com on Tuesday at the NFL owners meeting in Phoenix that he's still counting on running back Ryan Mathews this season to play a prominent role even with the addition of Danny Woodhead. "Ryan’s had some bad luck with collarbones," McCoy said. "That’s all part of the game. You can’t do anything about that. I don’t know how you strengthen your collarbones. He’s had some bad luck the past couple of years. He’s going to be a great fit for this system. Give him the ball as many times as he can carry it in a game. And get him more involved in the passing game in certain areas and certain ways."
