Chargers running back Ryan Mathews believes he'll bounce back from what was a frustrating 2012 season that began and ended with missed games caused by broken clavicles in his shoulders. Mathews tells U-T San Diego he's talked with a number of trainers and plans to apply their advice to his workouts this offseason in an effort to be a more complete player. He'll need to become just that as the story on Mathews adds that some in the Chargers organization do not believe he'll be a true workhorse running back in the league. "It's time for me to show them why they bumped up all the spots they did to draft me," Mathews said. "I've shown greatness at times, and I've shown I can be the worst player at times. You've got to be consistent, and that’s what I plan to do, Just be a little more consistent player and just be the guy they knew when they drafted."
