Omar Kelly of the Sun-Sentinel is reporting the Miami Dolphins worked out running backs on Sunday because they aren't pleased with the play of Kory Sheets.
While it is not known who the Dolphins worked out on Sunday some of the "big" name running backs currently on the open market are Clinton Portis, Kevin Smith, Lendale White, Tiki Barber, Willie Parker, and Larry Johnson. I'm not sure if any of those "big names" would want to come here and compete for a 3rd string running back position though. It is clear Bush and Thomas have their spots secured as the starter and back-up on this roster. If I were a betteing man I would think the Fins go after someone young and who might not be a household name.
