Probably the team getting junk.
Trading Lonzo for Elf is remarkably silly. The only reason they might ditch Ball is because he doesn't space the floor for Zion, so they're dealing him for a worse 3-point shooting PG, especially an older one.
Word is PELs want to move JRue who could bring a solid return.
And build with their young core of Lonzo - Ingram & Zionista.
Along with Jax Hayes & NA Walker.
They can likely add a shooter such as Nesmith or Bey with their #13 pick.
(looks to me like after 13 there is a drop off -- not to say there won't be some successes below that, but looks like a tier cutoff point)
So with all that yute, add in whatever return for Jrue -- hopefully a player and a pick. Then fill in the roster with some vets. For now they have Favors. Hart is useful. Find some more shooters and ball movers to fit around Zion's power game.
I'm not that high on their players and the mix, but the blueprint is strong, and they can figure out chemistry and team play over the next few years. Caveat: I haven't seen Zion much and Ingram improved.
