I think Flagg is a true #1 level guy. It's extremely early on, but the last 5 drafts I think I'd only have Wemby and maybe Chet (I'm a big Chet stan) ahead as prospects. In the last 10 drafts, I think Zion and Luka would be the only prospects I rated as ahead.
It remains to be seen if any others in this draft can approach that level.
