Chargers running back LaDainian Tomlinson, who turned 30 earlier this week, doesn't feel that old. "That's the one thing that I'm eager to prove, is that doesn't necessarily go for every player. Turn 30, that doesn't mean that you can't play any more," Tomlinson said Thursday. "There are some guys out there that defy the odds, and I'm eager to prove that." Tomlinson is coming off a career-low 1,110 yards rushing, though he still finished fourth in the AFC. "I can still jump pretty high, can still dunk the basketball," the running back said. "If I can't dunk anymore, it's going downhill."
