I may be stupid but I do NOT want the Jazz to include Favors in this hypothetical trade, nor do I think the Jazz are wanting to move him.
Favors is efficient, he can score which the Jazz need more of, even if not in the way of today's stretch 4. I think, or maybe it's wishful thinking, that the Jazz can still find that sweet spot to utilize Favors more to take advantage of his efficiency and scoring but not to the point where his efficiency drops (as tends to be the case when any player's utilization goes up).
I don't want to make this about Favors but I believe he's still vastly underrated by Jazz fans and that the narrative on him has been the same for so long (that his name is always in every trade rumor) and every one thinks every shooting 6'8" or larger big man is a automatically better. That it's just become lazy thinking, much the same way we berate the National media for some of their takes on the Jazz ..... any way I digress.
I do believe though with the roster as currently constituted Rubio or Favors while starting quality/level players one needs to be moved on from this off season. Despite them being such good team, chemistry, locker room veteran players and all those other little things we love about them.
