Stacking picks has done nothing for Boston. I'd give up a first rounder for him. I'd very likely move Exum for him but I'm pretty down on him. Can't keep and develop all these picks. The biggest thing to me is showing Hayward we are effing serious.
You also cant go all in on this year. The smart thing is to build for the next 3 years. Hope the Warriors cant pay KD and Curry the money they want next year.
