'The Bills announced Wednesday that former Carolina Panthers fullback Mike Tolbert has been signed to a one-year deal. The Tolbert move, combined with the DiMarco signing, is interesting. There has been plenty of joking on social media about the Bills bringing in multiple fullbacks. But Tolbert is a much different running back than DiMarco. Tolbert once rushed for 735 yards in a season. He's also a decent pass catcher. He'll be more than just a blocker in Buffalo.'
