Another thing to consider. Lonzo is currently injured and likely out for 4-6 weeks. He may not have as much value as folks think unless it's for someone like say, Vucevic.
Vucevic is a good player, but he is certainly no star.
It will have a dual purpose if the Celts can get Vucevic.
Celts can't sign Vucevic in FA if the summer because Celts have no cap space.
What I like about getting Vucevic is it will not affect the Celts chances of getting AD.
Celts can trade for Vucevic without giving up the assets needed for an AD trade.
If Celts can't get AD in the summer then the Celts just re-sign Vucevic to a big contract as the Celts will own his Bird rights if they get him in a trade.
