The physicality thing is going to be an issue for him for sure. It'll be interesting seeing how he adjusts to the typical 6'7"/6'8" bruiser a lot of college teams generally throw out there against Gonzaga. Wembanyama absolutely man-handled him in U-19 worlds. Then again, Wembanyama is quite possibly the single most impressive 17 year old prospect I have ever seen including Lebron (with all due respect to Bron, he wasn't a 7'2" behemoth with a 7'8" wingspan and Dame shooting range.
Right now Banchero is getting slotted ahead of Chet in some mocks, who kinda reminds me of a Julius Randle with better feet on defense. And Emoni Bates is now in the 2022 draft too and while he's not developed like people assumed he would two or three years ago (sub-par wingspan, super annoying dad dynamics gives me Marvin Bagley vibes), his offensive repertoire is legit.
Jabari Smith Jr., btw, is way more athletic than his father and actually has a bit of Dirk to his game last I saw him.
