Next year we should have an improved Yakwe and Sima, along with Owens. Williams, if he is able to stay healthy, has a significantly higher ceiling then Jones does. But if Willliams goes down again, Jones would be there as a fourth big just in case. But really, Ahmed could slide over to the four in a pinch so I don't really see a serious need for CJ next year. (Definitely would have him back next year if he wants to come back as he has been a good soldier for four years and he seems like a nice kid). But if he decides to go elsewhere for more minutes, it would not be too devastating.
Now if we don't get Alkins or Maker, we still have one more ship available. A juco or 5th year transfer, who is a strong post defender with some type of offensive competence, would be my preference. And in that case, Jones would be completely out of the rotation.
