I dont know about ranking all of them, but out of that group, Kendall Hunter, CJ Spiller and Stevan Ridley stand out to me. I think Hunter is the only one there who can help you this year, because Spiller won't get any playing time behind Jackson, and the Pats throw too often for Ridley to get more than 10 carries a game (on a good day).
Hunter looked good last week, and Gore didn't. Im thinking Harbaugh starts using him a bit more, and for next year, he'll have a solid role, i think.
Hope this helps.
