I more or less agree. I'd go Favors, Lyles (NOT Exum or Hood) and draft picks - not sure how many. . . but I wouldn't restrict them if it seals the deal.
Burks should get flipped for a pick or a contract. Either give the Jazz cap relief, or give them a contributor. Diaw should be used as cap relief for another team. Use that non-guaranteed contract to get more help. Maybe that's where your power forward help comes from.
You have to give up Exum or Hood.
