I don't know, this seems like a downgrade for the Jazz. The Spurs would be getting the best player in the deal. The only sweetener in there is Murray because all the other players are on expiring deals. I could see it happening if the Jazz really want to move on from Gobert, but they might want LMA instead of DDR.
That might be for the best anyway. Gobert is basically a billionaire's Poeltl, and while it would be nice to get 48 minutes available out of that role, Poeltl clearly signed his contract with the expectation of eventually starting. The Spurs would probably need to deal him away at some point and might not get much back due to being motivated sellers.
