Wow this is essentially Pascal for Suggs and a bunch of trash filler.
I would not say 'trash fillers.' You also need to consider the cap implications after this season for each team. Brooklyn would be on the hook for $52M in 2024 for the combined services of KD and Siakam, so moving him or KD would need to be in the front of the mind of the Nets owner. Advantage KD here I would argue as he is an almost bargain at $22/season if healthy.
C. Joseph actually is a backup/fill in option w/a little upside IF he or Hayes ae dealt in the offseason. More likely Joseph as he is serviceable as a backup or emergency NBA PG for a competing team. Either way, if one is dealt, both likely see an increase in value.
G-League players are like MLB prospects. You never know until they arrive. Scrubb hopefully is in the NBA more than not this season as he has some decent upside.
