Yea, I'd prefer young and future assets if it's not Simmons or Sabonis. If it's NO, I doubt they'll trade BI or Zion. I do remember Monte was interested in Jonas and Hart. So maybe Fox + Thompson for Jonas, Hart, Murphy, Hayes, and a first.

Once again, totally underselling Fox. Hayes is not going to get traded with his pending legal issues and has much as you like to undercut Fox, he's still a fringe-all star type talent at 24 years old signed long-term.
