Fluidity and coordination have nothing to do with athleticism/explosiveness.
He's an average (below on defensive) rebounder and below average shot blocker. Hell he's a below average defender as of right now. He turns the ball over a lot too (but since he can handle and has a higher usage rate I can somewhat understand) Alot of this is attributed to the fact that he's a bad athlete.
I also said this if you actually read
Yes he's coordinated and fluid with the ball in his hands. He's skilled on offense yes. But what about everything else?
Athleticism is about explosiveness i.e. running fast and jumping high. Fluidity and coordination are skill/sport specific. Which is why I said that he would, not completely suck at the next level, but struggle with finishing. But please continue
