I think Jones is a solid back so far. He's at >5 YPC for the season and only has one game where he averaged below 5 YPC. The last few games he's carried it around 12 times per game, I'd like to see that around 15-16. He's a solid back.
Robinson had a great carry against UTEP, but he has 3 games at <4 YPC and only one game over 5 YPC.
Jones isn't going to run away from people, but he's got solid burst and consistently gets vertical. The Auburn game was the only game where he tried to bounce runs and he paid for it, but I think he's learned he's got to be a north-south runner. He's built a lot different, but I have no doubt he can be a Hickson/Lawrence level back.
