Warriors make themselves significantly more interesting for the rest of Curry's career without really giving up much. Both guys make sense in Kerr's system and while Turner's defense has been on the decline I think a change of scenery could do the trick.
Bucks get 50 mil expiring, another young guy, and a swap for two guys with questionable contracts/fits as is. I think clearing touches for Rollins and Kas at the one, and having Burries/Ament/Jaquez/Podz on the wings makes a lot of sense.
