Remember that Kevin Pelton's WARP stat correctly projected Jokic and Embiid into the Top 10 draft prospects back in 2014 (alongside Nurkic and Capella) and it did similarly with KAT, Lively, Holmgren, and Kessler too. It has the capability to find productive centers, essentially. And on his recent projection, Clingan and Edey were on it.
Meanwhile, my own finding showcases that college centers who have freshman production on par with Clingan and Edey were pretty rare. Ayton, Holmgren, Duren, and Embiid are the other ones in recent memory. Oden, Robinson, Hakeem are the others in the three point era.
12.5/8.4 Per 28 minutes on 60 FG% as Freshman is elite. To be that advanced as a Freshman center suggests strong production numbers down the line. Certainly, Ayton isn't the ideal center he was expected to become and Pistons fans express that they wish Duren knew how to play defense....but their current roles in the NBA are really a question of effort or mindset and not due to lacking raw talent/raw productivity.
For Clingan, we know he'll exceed at defense and rebounding. It's just a matter of what his offense is and if he can continue making plays. 85-90% of Gobert on defense with pre-injury Nurkic type offense can be a strong player on a contender.
It's like....We'll see what happens next but I think people were far too quick to write this draft off
