I think Gobert gets traded. Mitchell wouldn't be traded until the KD situation resolves, since Miami is pursuing KD and may also be the front-runner for Mitchell.
If the Jazz trade Gobert and the package has solid wing players to play next to Mitchell, then it will look as though the Jazz are planning to build around Mitchell for a while.
If the Jazz trade Gobert and the package is very pick heavy with very young players coming back, then it points to a rebuild.
Possibilities should be:
** Gobert to Atlanta for Collins/Capela/young player/picks. See if Capela gets moved to T'wolves in the deal. See if Bojan gets packaged and sent to ATL to replace Gallinari.
** Gobert to Toronto for OG/GTJ and another piece, e.g., Flynn, etc.
** Gobert to Minnesota for a boatload of picks and young players picked up in the draft like Walker Kessler, Wendell Moore, Kendall Brown
