Please see my top 20 below, Feel free to comment on mine or leave your own.
Here is my board
1. Okafor- I still think his post scoring is so valuable in today's NBA. With every team going small and running the ball, Okafor will punish teams who attempt to do so. His defense isn't great now but I think he will end up being a similar quality defender to Hibbert once he gets in shape.
2. Towns- Skilled 5 who can defend the rim, shoot and score from the post, more rounded than Okafor but Okafor's best talent is better than that of Towns
3. D'Angelo Russell: I think he is going to end up being a franchise level scorer, hopefully his defense improves.
4. Mudiay: I've only seen clips but his strength size and athleticism at the point guard position give him a high upside even if he is an unknown.
5. Porzingis: Again only seen clips, but he is extremely long, can shoot and is mobile. He is skinny but I think he has the frame to gain weight.
6. WCS: I love WCS, but he doesn't have the upside as an offensive player that the guys above him do. He has the makings of an all NBA defender some day
7. Justise Winslow: Great defender, great athlete, great in transition. Can make the spot up 3, just don't ask him to create.
8. Mario Hezonja: He is only 20 and playing in one of the best foreign leagues in the world. He is tall, pretty athletic and can shoot. Worry about the rumors he is difficult but I think he will be able to score at the next level.
9. Stanley Johnson: Has the strength to be a really good defender at the next level, and I expect his mental lapses on that end to abate as he matures. I prefer him to the other SF in the draft because I think he is the best at creating shots for himself, while Oubre, and Winslow are more spot up shooters.
10. Turner: Will be able to block shots in the NBA and knock down the 3 once he develops. I think he could be very good but the way he moves makes me very worried about injury.
11. Oubre: Long, athletic and can shoot. He reminds me of James Young, except more athletic and less clueless on defense. He is a project but could pay dividends in the long run.
12. Looney: He is going to be a stretch 4 in the NBA, who can block shots and knock down the 3. He might take a little while to develop but his length and shooting potential make him a high pick.
13. Booker: Can really shoot 3's and this is a 3 point happy league. i see him eventually learning to create for himself off the dribble but will be a good spot up shooter immediately.
14. Kaminsky: A similar player to Olynyk in that he will be a stretch big in the NBA. The differences are Kaminsky is a better defender (not great but passible) and he doesn't overpass on open shots.
15. Trey Lyles: Overlooked because of the team he plays on, while playing out of position because it's best for the team. He will be a stretch 4 in the NBA with a midrange game that will eventually move out to the NBA 3.
16. Sam Dekker: Great size, good defender and if his 3 point shooting in the tournament carries over to the NBA he will be a good rotation 3 for a long time.
17. RHJ: Will be able to come in and immediately defend at an NBA level. Does the little things to help his team win. Unless he can learn to fix his broken shot he won't be an offensive option in the NBA
18. Malik Pope (if he declares): a 6'10 SF with a great looking shot. He is a ways away from developing but when he does it could be something special.
19. Cliff Alexander: he came into college as an elite recruit then Bill Self did his best to decrease his value. He has great length and strength, I'd be willing to take a run at his upside if he is there with the Clippers pick
20. Kris Dunn: Protypical nba point guard size and great athleticism. I worry about his ability to stay healthy and turnovers.
I hope we somehow get lucky and get two of these guys.
