The Panthers signed Mike Tolbert this offseason and plan to use him as a fullback paving the way for rushers DeAngelo Williams and Jonathan Stewart. "Everybody keeps saying he's a tailback. But he's a fullback to us," Panthers coach Ron Rivera said. "Because again, we saw how we had used him in San Diego. We just thought this is a guy we'd love to have. ... If you can put an athletic, play-making fullback there, I think it helps you."
