Chargers rookie running back Ryan Mathews wants to make it clear that he isn't going to try to replace LaDainian Tomlinson. Mathews idolized Tomlinson to the point that he wore No. 21 while at Fresno State. He respects Tomlinson's legacy and is not trying to replace him. He says he'll do his part to help the Chargers win and hopefully begin building his own legacy. "I'm not L.T. I'm not in here to try to be L.T. or I'm not in here to try to replace him," Mathews said. "He's a legend. What he did here is forever going to stand in the record books. For me looking up to him, I'm in a wonderful position. It's a gift just being able to follow his footsteps and what he did, to be in the same position, same locker room, same teammates, where he just dominated. "He set a lot of good building blocks and stepping stones for me to start my career off. He just did a wonderful thing."
