I agree with not giving up Exum, Hood, or Mitchell & not sure I would even give up any picks regardless of protection (unless we intend on making additional moves to remain competitive-which would be a mistake IMO).
If that's the approach we choose, Favors for Crowder is intriguing (assuming we intend to use him as a 4/3).
What do you mean by it gets complicated? Financially?
It requires Olynyk and Jerebko to want to come to Utah for whatever it would take to match salaries so the trade would go through.
