As I've been saying, the Jazz view Favors as a center and since he's already signed a contract extension and had a relatively decent season, he's locked up as their starting center. One of Kanter or Gobert will eventually be traded and since Kanter's rookie contract ends after this season, expect it to be him. Not much point in tying up that much money at the center position by re-signing Kanter.
Of course, this is dependent on how everyone performs. If Kanter or Gobert have a season that's more promising than Favors', we might see Favors eventually traded. But suffice it to say, keeping all three guys around for the long haul is not part of their plan.
