Without knowing what's going on behind the scenes and based on a hypothetical:
1. He's open to moving anyone but IT and Horford; 2. Smart/Crowder are available for a big like Noel/Nurkic; 3. Smart/Crowder/Bradley/Brown are available for Cousins, if there's any interest; 4. No trade gets done prior to the draft:
Fultz (elite, fits with IT)
Ball (same)
Tatum (Upside, team need, Pierce, possibility of he + Brown)
Smith Jr. / Jackson - (IT4, otherwise #3)
Isaac (size /athleticism, upside, Zeller/Jerebko/KO/Amir)
Jackson / Smith Jr. (could be special, but Brown...)
Monk (team need, esp if Bradley will be available)
I may be way off, but it looks like a really good draft.
