I'm more sold on Murray or Mathurin than Ivey. There's a certain amount of positional flexibility with them...with his wingspan, Murray could potentially give you minutes at 3,4, or 5. Mathurin could play off Cade as a guard or a wing. Ivey seems locked into being a guard and his shot is a bit more questionable than the other two.
Be nice to take Hayward and 13 off of Charlotte's hands...be in a position to draft a rim protector like Williams from Duke or frontcourt help like Socha or Griffin. Although Koloko at 36 might be the way to go for a interior defender.
