I'm wondering what sort of changes he does need to make 'bout his gameplay

. More shots from down town? It just seem that he's already at his peak.
Agree. Whatever development he can gain while he progresses, even shooting lots from the downtown, without consistent support from his teammate, it will be hard work to acquired the Larry O'Brien trophy.
We can't compare him to LBJ that can carry an average team*** because their main forte' is different. Giannis is not that perimeter shooter that's why he needs to be partnered with good role players
(although in my own view, he is already surrounded with good role players since then but I don't know why they are still struggling during playoffs).I don't know what's the other plan of Milwaukee Bucks. Taking care and securing Giannis is useless if they will not look at the branches to support the tree. They are literally choking every playoff. They should at least learn about what things they are lacking since the Raptors shutdown Giannis in their 2019 playoffs match.
