Feels weird to me we're constantly talking about issues with the "two timelines," and now Warriors are trying to hit again in the draft. Why draft another prospect who is inevitably going to ride the bench when your window with Curry is starting to close? Kuminga is at least playable for some minutes, and you can do much worse than him in the draft.
If you are not going to blow it up, then I think it would be a lot better to package Kuminga for another player at least, and then you can try to contend next year. Or just play him more. Despite the rumors, Kuminga has shown some promise at least.
