I realize this is completely based on opinion, but I literally think the exact opposite of nearly every single thing you said. To me, his best attribute his his speed with the ball and using that to set up others. His handle is actually ok for where he "needs to be" but it can be improved and that can help him become more of a full-time PG. Although he may not "need" the ball in his hands, I 100% disagree taking it out of his hands can get the most out of him. I also disagree in the notion that putting the ball in Exum's hands for some reason lowers Mitchell's usage. I think it will do nothing but help Mitchell. We aren't choosing one to be a PG, anybody who watches the Jazz knows that the "PG position" is nearly nonexistent in the traditional sense, and the primary ball handler may rotate every single possession.
