Who's the next great Arkansas running back?

Remember when Cedric Cobb left we all wondered who could possibly replace him? We get McFadden, Jones, and Hillis. Then those guys leave, who could possibly fill those shoes right? We get Knile Davis. Davis goes down. Can anyone pick up the slack? Dennis Johnson averages nearly 6 a carry. So now with those two gone, who's the next great Arkansas runningback? We always seem to have a guy come out of nowhere. Very rarely have I seen a lull as far as lack of skill in the backfield in all my years of following Razorback football. Any predictions?
