The Lakers give up almost all their picks for Paolo Banchero and Anthony Black. Now they will have more size all over the court to protect Luka and become more switchable and versatile. If Moritz Wagner declines the trade, they're probably going to have to stay with no big man.The Lakers become more versatile and slightly better on the perimeter as they are more switchable. Anthony Black will boost the perimeter defence significantly whilst being a secondary ball handler along with LeBron. This trade works because when LeBron retires, the Lakers will be full of cap space and able to sign more players.
They could possibly go ahead and sign players like Trae Young this offseason if he declines his player option or if he doesn't get traded. The strategy would be:
Sign him for one year
Then look to possibly trade him for picks
