If they go for the three star approach, it'd all be with an eye towards who do you want to pair with AD after LeBron. That could be Trae Young, Donovan Mitchell would be a better target, etc. They may also opt to keep some flexibility and upgrade the supporting cast around LeBron/AD and see what better coaching/player development provides. They'll certainly be active in some capacity.
I kind of feel like LeBron is planning on LA taking Bronny in the 2nd round, playing one year with his kid on the roster and then retiring. He may not be getting the same amount of front office influcence right now as he has before, given that he's got only a couple years left in the best case scenario. However, spending a 2nd rounder to keep him around and happy in exchange for having his hands out of the coaching/roster decisions seems like a good trade off.
