I will be on this thread making a comparison later on. As of now he looks like a guy who is thinking through his decisions rather than showing his plus length and athleticism.
So far his jumper has really impressed me, as has his ability to roll to the hoop. I think once we see him more comfortable you will see him rise up and dunk on the defense where so far he hasn't played above the rim a ton imo.
I think he'll be a rotation player in a couple years once he gains weight, increases his range and becomes more comfortable knowing where to be on defense. So far he's still learning when to commit to the block and when he should box out his man.
