To get there without BI or Zion, the trade would have to be something like
Jonas, Graham, Temple, Hayes, Kira and then the Pels could offer some combo of the 6 picks they can trade (their own in 23, 25, 27, 29 plus Lakers 24/25 and Bucks 27) plus I would guess at least one of Trey, Herb, or Daniels
If they put all/most of that on the table, you can probably get KD via a 3 teamer where some of those picks and players go to a third team for an established star.
Let?s say you had to give up 1 of the players in that deal - Herb, Trey, or Dyson - which one would you choose?
