Yeah, the most obvious way I can see him being better than Gobert is those like 5-8 foot push shots, but unless you're elite at them they are usually poor shots. I also think we kind of forget how good Gobert got at layup finishes around the rim off rim rolls. He got really good at those fully stretched out layups off the PNR. I do think we underrate some of Gobert's non dunk finishing.
The over thing that may be in reach is just drawing more fouls. He does have better offensive body control than Gobert, so if he can leverage that to actually draw fouls he has a shot. I do expect WK to eventually be a better FT shooter than Gobert was, but I'm not fully confident he will ever draw them like Gobert.
