I strongly believe the difference is most of the time made with all the intengibles you can't mesure, like entourage, work ethic, IQ, charachter/determination etc
ZR already checks the box in terms of size, length, fundamentals. Then you add his entourage (dad former pro) and pre-NBA career built smartly step by step like Wemby's (he also changed club for a more adapted one with more playing time for ex)
I just heard on the Lowe podcast Givony say that ZR actually played 75(!!!) games. It's insane at his age and it's not surprising that you find streaks where he's less poductive ... at 19yo ...for his 1st eperience ... vs pros men
The same logic could be applied to other prospects in the draft in terms of entourage, ethic, IQ etc but the collegian level is really weak and 1 short season vs very diverse level of opposition doesn't give you a proper idea.
I don't see ZR as a future allstar tbh but a very versatile and reliable role player who won't have playmaking duties but will be able to defend 1-4, cut, pass and shoot the 3
I'm 100% sure he'll have a long NBA career, not sure at what level.
Most other picks I like in this draft (Reed Dilli Castle Holland Cody for ex) have maybe better upside but bigger bust probabilities as well imho
