Philip Rivers has finally entered the NFL MVP race. "I think he should," running back LaDainian Tomlinson said. "What he's done, in terms of touchdown-interception ratio and completion percentage and winning football games makes him deserving. It's wrong if he's not considered a legitimate candidate." "I've been as consistent as I've been, but there's still room for improvement," Rivers said after Wednesday's practice. "The goal is to keep ascending, which is what we strive to do."
