Here are some of my comps for draft prospects. Keep in mind, some of these are based on role and impact rather than literal comparison as athletes/measurables.
James Wiseman: He's Deandre Jordan with the potential to do a few Joel Embiid things--shooting, limited postups--assuming teams would want that from him. I wouldn't compare him to Bosh, unless he can really shoot it. He's a significantly better and more mobile athlete than Whiteside, and I wouldn't make that comp.
Anthony Edwards: I don't have a good comp for him. I think his talent level and impact might be comparable to RJ Barrett from last draft. He can get on the rim easier than Barrett, but might not shoot as well. If he completely flops, he'd be Shabazz Muhammad, but he won't completely flop. I'm okay with Oladipo comps--a high-volume, limited-efficiency scorer.
Lamelo Ball: I'd agree with the Shaun Livingston comp. I think he's a bit overrated.
Onyeka Okongwu: Agree with Sam Vecenie's comps. He's the turbo-boosted version of Tristan Thompson. Will be a better rim protector and roll man than Thompson, but not as offensively versatile or laterally quick as Bam Adebayo. I wouldn't compare him to Bam. He can't dribble, pass or shoot much right now, so I'm not super high on him. I think functionally he's only nominally better than Achiuwa and the Stewart kid from Washington when it comes to translating to the modern NBA. He could also be like a mid-career version of Dwight Howard if things really click, but the league is moving away from that type of player.
Tyrese Haliburton: You're hoping he's SGA, but he's not as crafty or downhill with the ball as SGA, so he's like a lesser SGA.
Killian Hayes: I really like him. I agree with the D'lo comps, but he's a more natural floor general and more of a triple-threat than D'lo. His versatility may be a bit underrated.
Aleksej Pokusevski: I really like him and think he's one of the sleepers in this draft. I've compared him to the underclassman version of Keith Van Horn and I'll stick with that. He'll add 20 lbs and look like the Latvian kid on the Wizards Pacesniks, but Poku is much more fluid, mobile and skilled. He could be a legit triple-threat player at 7 feet.
Tyrese Maxey: I like the Coby White comp. He can shoot pretty well, work as a secondary initiator, finish a bit inside. Good athlete, not great. Not as shifty, wiggly or crafty as McCollum.
Patrick Williams: I agree with Vecenie that he could be OG Anunoby, but if his ball skills develop, he could be an All Star-caliber player at the 3, not unlike Jimmy Butler. That's probably a reach, but the ceiling is high.
Saddiq Bey: Nice 3D wing and legit shooter with size. He'll have some nights where he really goes off scoring the ball. He's got more handle and body control than Robert Covington, but I can't quite say he's as talented as TJ Warren. He's somewhere between those two.
Paul Reed: His role and impact could be like Josh Smith--a disruptive defender all over the floor, who can also rebound and go, drive downhill and get on the rim. He's not the same vertical athlete as Smith, but he compensates by being a better horizontal athlete. Like Smith, he has a funky and possibly unreliable jumper.
Josh Green: Should have a role and impact that's similar to Donte Divincenzo. He's not as explosive athletically, but he's bigger and a touch more disciplined. Green can likely swing to play the 3.
Jaden McDaniels: I think he's basically the Kelly Oubre of this draft. He'll do some 3D and make an occasional big play at the rim. I'm not sure his ceiling is really all that high, unless he improves his body and his handle to develop a driving game.
