I agree they should treat him well. But he's the one that wants out. Why should Utah pay the majority of his remaining salary? He wants out they should trade him if possible somewhere he wants to go. If that doesn't work then work out a buyout, but it shouldn't cost the Jazz the majority of the remaining salary to do him a favor.
In the end it doesn't matter much. The salary comes off the books so even if they buy him out for the full amount then it doesn't change the future.
