Exum (and a 2nd) for Mirotic.Then what will they do if they use Favors to match Conley's salary? We're thin at that position, and they're definitely planning to bring some else in.
Or whatever, frankly. There aren't a lot of lumbering 4s in the league that will win a matchup so handily against the Jazz that it is a net-positive. That isn't to say that the Jazz's situation at the 4 couldn't be a lot better than filling the position by committee (Jae, Royce, Joe, Thabo).
However... the Jazz will be cap-strapped if they get Conley, so having Mirotic's Bird Rights at that point would then become pivotal. Hmm.
