While I would love to get Young and one of the bigs, that probably is wishful thinking. So, as long as I am hoping for best-case scenarios....
We draft Luka Doncic.
The draft goes...
1. Deandre Ayton
2. Luka Doncic - Suns
3. Marvin Bagley
4. Michael Porter Jr.
5. Trae Young
6. Collin Sexton
Then we trade the Miami pick and Warren for Bamba. (I think Warren is the guy another team would want and, while I like him and think he has a great contract, I'd rather free up Jackson to develop fully at SF, particularly with my offensive-minded backcourt. Including Warren might help us keep the 2021 Miami pick as well.)
Avoid big moves in free agency. We will need to start signing our own young players soon. If we can't keep Len at a decent rate, keep Chandler. If not, move on.
PG Doncic Ulis Canaan
SG Booker Reed Daniels
SF Jackson Free Agent Draft Pick
PF Bender Chriss Dudley
C Len Bamba Williams
Eventual Lineup:
Doncic
Booker
Jackson
Bender
Bamba
Reed
Chriss
Len
If your backcourt can evolve to become average defensively and your frontcourt develops some on offense, that could be an explosive, talented team with everything you need to compete. Doncic and Booker as offensive stars with a long, active defensive frontcourt.
