and since he had the same YPC, that means those 600 yards are statistically due to having more carries.
Look, my point in all of this wasn't to get into a pissing match about whether Benson or Jones is the better back. It is trying to compare apples to oranges at this point.
The idea that the Bears *have* to go get a starting RB is quite laughable. While I am sure they, like any NFL team, are considering all of the available options, it is very possible that they view Benson as their main guy at RB.
