You're not comparing Ahman Green to LT are you? Green never is, was, or ever will accomplish what Tomlinson did. I'd still be iffy on bringing him to the squad. He's on a fast decline and he is not getting any younger, fast.
I think he's saying what you're saying. To be a "little" fair to Tomlinson, none of the Chargers backs did anything. Darren Sproles got all his big plays in the passing and return game, NOT on the ground. They are similar to the Colts, Texans, Cardinals, and Patriots with having good passing teams and weak running games no matter what RB they threw back there. Tomlinson has declined no doubt. He better realize he's a 10-13 carries back the rest of his career.
