The Facts: Following up on the ongoing story. ... Here's a little more evidence that the Panthers really are planning on using Tolbert at fullback. They're paying him like a fullback, not a tailback. Tolbert got a four-year deal worth $10 million. That's an average of $2.5 million per year. That's classic fullback money.
