So to add to this, it seems like Boston and Hayward are working to extend his option date until after the draft. This could mean one of two things. Either Hayward wanted to prevent the Celtics from dealing him on draft night (unlikely) or Hayward is gone no matter what and is giving Boston the chance to move him to a team he wants that'll let him keep his salary.
I wouldn't be surprised if that team were SA. They have LMA as a matching contract, and they could also throw Mills/Gay/Poeltl at the Celtics for Hayward and Kanter. If Mills gets rerouted to Philly for Richardson (who'd go to Boston for one of their late firsts), Gay stays in Boston to replace Hayward as the bench PF and Jakob becomes the Celtics' center of the future. If this is a no-picks deal or at worse a deal where SA drops to 14, I think it's worth doing.
Murray, White, vet PG
Johnson, Walker, Weatherspoon
DeRozan, Woodard (41)
Hayward, Lyles, Samanic
Aldridge, Smith (14), Kanter
That's an underrated team in terms of talent. If they can bring themselves to flip Murray and White, I think those units could compete with at least the second tier in the West.
