Conspiracy theory here:
Is it possible the Jazz really don't want him back at full speed/game shape this season? Give him some minutes - for example, 10 per game - to let him start to mesh with the team. But if Dante were to be in the rotation full-time (20-25/per), shoots well, shows his speed and defense, that could very well really push up his market value. The draft doesn't have a lot of lottery-worthy PG's or combo guards. Rebuilding teams, who will have payroll costs up to the floor whatever they do, could decide Dante is still young enough to be part of their future and sign him to a large offer sheet. Utah matches up to a certain point, but I'm sure they want to get Dante for ~$10m.
Just a thought.
