I posted this in the Brook Lopez trade comments section, it's relevant here too.
For everyone who considers including JJ and Amir in trade proposals
"I’m not sure Danny sees it as you do. They were deliberately signed with a second year non-guaranteed. The reason for this is to enable Danny to go into draft night with "expiring" contracts worth $17m which he can use to get a star aka Demarcus Cousins. Inevitably in a trade for Cousins we would have to take bad a "bad" contract, either Belinelli or Koufos..or maybe Gay if you consider that bad.
Unless including one of them means returning us a star in season, they aren’t going to be traded. Their value isn’t in their play but in their contract. From Danny’s perspective, why would you trade Amir and not Lee, why would you trade JJ and not Turner?"
Another poster after me pointed out that in the summer we can trade their combined contracts to take back $22m in salary. That's a very powerful option. I'd rather take that chance than have a rental of Ryan Anderson.
