I would really love to see whats the possible return for trading Barnes, Holmes, Bjelica, Hield or others. If Barnes nets you a first and a prospect, pull the trigger. If Holmes nets you a first, pull the trigger. If Hield nets you anything meaningfull, pull the trigger. If bjelly nets you couple of seconds or even one good second, pull the trigger.
Focus the rest of this season and the next one for getting a very high pick and adding future assets. After one year come to the market with good cap situation, (over)pay ~180mil to similar guys like Barnes and Hield (that will not most likely be a problem) and try again with two additional PREMIUM draft prospects playing next to Fox and Hali with another bites of the apple (additional 1sts). That situation to me sounds so much better than using the next two seasons to fight for the 10th spot and drafting at a position where the possibility to draft a franchise changing player is almost non existent.
