He doesn't have a go to post move but claiming he hasn't improved offensively is absurd. His hands have improved a ton, he can put the ball on the floor now in transition, he has a spin move and much improved footwork and pump fakes overall when he rolls.
I don't want him to become another Al Jefferson or Kancer anyway. I think a hook might get better but that's about all I need to see outside of a pick and pop, but those are low efficiency for most so who cares.
I'm not going to argue against a guy who has one of the league's best Ortg-Drtg differentials. 129-99 last season? That's unreal. Plus, he led the league in ts%. I'll take 14 points a night from a center with 68 ts% over anything we've seen in a long while. Plus, he led the league in screen assists in 2017, so yeah, I'm going to point to it.
