The answer is Jimmy Butler and a playable big (Looney or similar). But, i think even if we don't get Butler we're still looking for the same things. A big wing and a solid center. I think Capela is gone no matter what and the celtics deal just changes to Jaylen Brown instead of picks. Then we use the mle on a center. I think they'd try to move Gordon as well but won't if they can't get equal value back. Trading big for small (like with Capela) is much easier because a good big on a value contract is hard to find.
So Danny Green, Iggy (Target from last year), and Looney are the only targets left. Maybe JaVale as well. Hope the Rockets can get something done with at least 2 out of the 4 here.
