outside of their size, appleby and boopie are completely different players, imo.
appleby was super quick and had amazing vision. people always talk about marsh alley-oops but the super hard part about that is getting the defense into a 1-on-2 situation where they a big has to either leave the guard unopposed or help off their man in the dunker spot. getting the defense into that situation is not easy.
boopie is a good scorer and particularly good at getting off / making contested shots. he's not a natural playmaker* (which imo is not something that can be taught easily). i think he'd do really well off-ball, in particularly attacking closeouts because he is pretty explosive with his first step.
*i think there are three major aspects to being a "playmaker."
1/ put pressure on the defense (i.e. get players outside of the guy guarding you to have to react)
2/ keeping the option to either shoot or pass as long as possible (it felt like our guards, inc. boopie, were in scoring mode by default until that option was blocked)
3/ being a good passer (seeing the floor, being able to anticipate what players are gonna do, actually making accurate passes)
i would say appleby was good at all three, elite at #1. alondes williams was also good at all three and elite at #2 ands #3. optimistically, you could say boopie is approaching average at #1, maaaaybe #3.
