The NFL is not a league of "one starter" anymore, its definitely a 2 back league and definitely 2 backs with different skill sets. I understand the game of football, you dont have to talk to me like Im a little kid with your: "cant understand why this pretty simple point is so hard for you to grasp?", "Let me clarify one more time for you", If jerry wants them both to be here, they will be here, its not a case of career back up, how many teams do you now see using a two back system? Probably more than 50% of the league, the game is more physical and backs in general dont hold up as well.
My answer to this situation is simple: Choice is under contract through next year, take some of barbers carries away and utilize him more for short yardage situations and his "closer" role, get the ball in Choices hands another 5 times a game to assess where he is and see if he truly is the back to pair with jones for the long run then draft a back in the 3rd or 4th round next year for special teams and back up-, its pretty simple actually if you werent so busy trying to be slick and condisending in your replys. The bottom line again is: If both backs prove worthy and Jerry wants them, they will both be here and barber will be gone next year.
