Leave out the outlier centers -- Embiid, Jokic -- for the purposes of a lottery pick. If a guy isn't elite, a lower lottery pick is still risky.
Duren's reported (non-combine) measurements: 6’9.5” w/o shoes, 7’5.25” wingspan, 250 lbs ... really nice.
Centers who can hedge and slide their feet then get back to defend the hoop ... cover ground to defend the corner 3 ... have value. If he can do that with his size and musculature (holy crap), okay. A possible pick especially if trading down? [I wanted the Blazers to go after Robert Williams in trade before he blew up. Pritchard, too. RW is valuable even without the scoring that Duren can do.] Nurkic gets signed regardless of the pick or trade (unless it's Ayton). Nurkic has too much value not to sign him on a < $20 million yearly deal ($14-16 for 3-4 years ... okay!) Would Duren be a back-up C in the short-term? Yes. This would be plenty for him as Nurkic isn't a 30-minute center so far. At such a young age, could Duren be Portland's Bam or Ayton? Maybe. The raw tools are there. Nice to hear him in an interview -- intelligent, well spoken.
Fixing the forwards for Portland is a must-do. Get Duren, too? Okay.
EDITED: [one more comment] Quickly rewatching Mark Williams of Duke -- who is not in the same class athletically with Duren. Long, tall ... good college center. Remarks about being "heavy" footed look accurate. Hops aren't a problem with ht/length but more of an old school center. Duren gets up pretty quickly and again.
