I've heard interest from the Warriors something to the tune of Wiggins, Wiseman, Moody, and potential picks for Rudy. I dunno if the Warriors would do that and say they win it all but if that was an offer, I think that is potentially the best of the lot. It's unlikely they give up Kuminga, he is crazy talented for a 19-year-old.
The other question is, would ownership have the stomach to trade him to the Warriors already with Steph, Klay, Poole, and Draymond? Might go into the fetal position for the first Warriors/Jazz game next year.
Wiggins (expiring), Wiseman, Moody and picks is a good haul for Rudy. The Jazz could either take it as is or bring in a 3rd team to augment the return for Rudy. For example, the Hornets could take some of the Warriors' package and give the Jazz a player and picks #13 & #15.
