If they keep them both then by all means have an open comp in camp for the starting job. But Jones is not an elite back, he has been in the league long enough to establish himslef as an elite back, I'm not saying Benson is that, but you don't know what you have with Benson, with Jones you know you have a guy who isn't the greatest at breaking tackles, doesn't have break away speed and doesn't hit the hole quick enough.
