I think Exum has a lot to prove, but I could see Favors going 4th or 5th depending on how Andrew Harrison does.
I mention it, because a fall-back position for the Jazz would be to trade Favors and a pick to move up into the top 6 for Parker or one of the Harrisons. Gobert will probably provide good rim protection and pick-and-roll defense when he bulks up. The combination of Kanter on offense and Gobert on defense might make Favors moderately expendable, if need be. Adding an elite wing gives us better floor balance.
I think this coming season should really tell us how good Favors can be as a defender. If he can consistently be our defensive pivot, and give us scoring here and there, I think he's not worth trading for anyone not named Wiggins.
