3. Jonathan Kuminga
His value should be obvious as he is the most proven of the Warriors' young players. Kuminga took a notable leap that many believe may have been a sign that he could be a potential star. Having him around to develop could make him the Jazz's next franchise cornerstone.
Kuminga's not exactly the most efficient shooter, but his athleticism, defense, and ability to create one-on-one makes him a very exciting prospect. Sadly for the Warriors, Stephen Curry might be gone by the time Kuminga hits his ceiling.
On the Jazz, he wouldn't have that pressure to produce at a high level and would have plenty of time to figure out what kind of player he is. The turnoff for Utah would be that his rookie contract is almost up, and he'll want to get paid. Knowing the Jazz's cap flexibility, it's not like he would be the worst use of their money long-term.
