What do you think about his stat? I think the games he focused on being a blue collar rim runner he did amazing. I don’t think this is only the Spurs fault or lack of point guard, he is enamoured of playing like a wing, which to me is the origin of most of his inefficiencies on offense.
Post ups/finishing are less about pure height, but being able to body through sheer force and/or slither through traffic with athleticism. Shaq and Barkley respectively being the easy examples. Sticking your hands up and just flipping it in is a bit harder since you’re stuck in whatever position you are standing + requiring a good passer to get you there in the first place. Basically a weird sky hook. That will take some time to develop against NBA talent
