I have seen some draftniks junkies also rate him on the second tier of prospects going as high as 5 in terms of their projections because they think he has the potential to be an all star talent.
Sometimes I look at past drafts and reflect on how guys going later turn out to be better than the top picks. Sometimes it's not evident, but other times, its someone that has one perceived flaw that on hindsight shouldn't have let them fall as low as they did. Duren is that kind of a high floor/high ceiling project. No player is guaranteed to hit their high ceiling, but at least the high floor means you will end up with a player, a real rotation player, and I think he will be at least that. Then because of his youth, who knows what he is yet to add to his game? He could end up being better than someone like Chet... In 5 years from now everyone may wonder how Chet went above him for example. It's not consensus now, but it could be in hindsight. This person had Jabari Smith as tier 1, and then 4 guys in tier 2, and those players in tier 2 had all star potential. Chet, Banchero, Ivey, Duren were there.
It just made me think about Duren. He's also kept his workouts secret. If someone does like him a lot, it's possible he's not even available at 9. The referenced tweet, not anyone known or anything, but I do wish to give credit instead of stealing ideas from somebody.
