Yeah, I don't know if you can ever predict a prospect being a star. It's a little bit of a luck of a draw which guys actually turn out and who doesn't. What you can predict are the tools a guy enters the NBA with and Jabari's are about as valuable as you can possibly get for the current NBA. I honestly don't even know who you can compare his tools too, because of how good his shooting is. Maybe like better shooting/ far worse creation Pascal Siakam? JJJ with more defensive wing potential?
I hate getting into get into this comparison of Diabate to Smith but. Both players are great athlete's. They can both run fast and jump high. They both have good reflexes. What I've never understood is why it's necessary to degrade one player in order to promote another. I like Diabate, but right now, today, Smith is the significantly better player, and if I may point out, Diabate is 20 years old, while Smith is 18 years old. Diabate is still a bit on the thin side at 208 Lb's, while Smith already has the makings of an NBA body at 220 Lb's while both players are around 6'10".
Probably the only edge I would give Diabate is that his ball handling may be a bit better than Smith's. Neither player puts up awe striking rebounding numbers, but both players play next to 7 footer's that gobble up boards, and Smith plays on the perimeter a lot. When it comes to shotblocking, and steals, Smith is the clear winner and it's not even close. Smith is the far superior defender with a defensive rating of 89.3, versus Diabate's 103.0 rating.
Lastly Smith is one of the best 3 pt shooters in college this year averaging over 40%. 3 pt shooting is not Diabate's strength who is averaging 21.4% from three. I'd also like to point out that Smith is the focal point of every opposing teams defense. Diabate isn't!!!! I seriously doubt that Smith will have a difficult time getting his shot off in the NBA. He has a lightning quick release, and a very high release, making it very difficult to block. Smith isn't perfect, but for an 18 year old, he's far ahead of most 18 year old's. Probably comes from having an NBA father and starting to play basketball at age 5.
As I said, I like Diabate and to be honest, I have no idea where he'll go in this draft. There are a lot of bigs with similar resume's that he has to compete with. Christian Koloko, Ibou Badji, Mark Williams, Ismael Kamagate, Trevion Williams, Oscar Tshiebwe, Hunter Dickinson, Zach Idey, Isaiah Mobley, Ariel Hukporti, Kofi Cockburn, and Khalifa Diop. All these players except for Tshiebwe are 6'10" are over. All are talented and a few, ten years ago, would have been lottery picks. My point is that when your trying to decide where a player like Diabate will go in the draft, it's tough! That's a lot of competition. As they say, beauty is in the eye of the beholder. I personally think he'll go somewhere at the top of the 2nd round.
In today's NBA you better have one skill that you can hang your hat on. If your a big, then you either have to be able to shoot the three, or be a great rebounder, or be able to defend the basket. If you can do all three, then your moving into rare air. So this is where scouts are probably having a hard time placing Diabate. He's not great at any of those things. He doesn't block shots, and can't shoot the three. He does have a pretty good midrange jumpshot. He's a decent to good defender, but not elite. That probably puts him in the 2nd round. He does have a great motor and will score you a bunch of points at times on pure hustle, and to me that's a skill in and of itself.
