Darren Sproles, who will be a free agent this spring, wants to stay in San Diego but there may not be room for him and LaDainian Tomlinson in town. Chargers' General Manager A.J. Smith said he would love for Sproles, taken in the fourth round in 2005, to remain with the team. "I don't think the Chargers can keep him unless they decide to make him the guy," an agent said. "He's going to be paid like the guy." Of course, that would involve trading LaDainian Tomlinson, who at 29 has three years left on his contract.
