He *might* be someone to watch next year. Let's look at the backs Carolina have:
Stephen Davis - I think it's safe to say that he's not going to be a major producer next year. I could see him restructuring his contract to make him cheaper next year and still playing, but he's too old and too fragile for anything over $1M. He's probably due some bigger roster bonuses since we're now moving to the backend of his contract, and that may also cause his outright release.
DeShaun Foster - His contract expires at the end of the regular season and while he's a solid candidate for the starting job next year he's also had injury problems. Moreover, he still is only averaging 3.8 YPC this season (3.9 for his career) which would need to improve.
Nick Goings - He's a stopgap for every time the Panthers have two backs injured. Again, another sub-4 YPC average.
Eric Shelton - If I remember correctly the main reason Shelton was shelved was he didn't have a solid grasp of some of the more technical aspects of the game, such as pass blocking. He also "ran high" which the coaches didn't like. Other than that, he was taking the goalline carries with the 1st team during preseason.
I think there's some upside to Shelton for next year, but it does depend on how the free agents play around this offseason as there will be a ton of movement.
