Solid post. IMO I'd move Myles Turner to the "can they keep it going" section and add more question mark guys like Justice Winslow, DiAngelo Russell, Aaron Gordon, Jabari Parker and Julius Randle. Too bad Anthony Davis and Bradley Beal just barely missed the cutoff as well. Overall, pretty spot on.
I definitely think there is a solid group of guys, all of whom you mentioned, but I still think all of them are just slightly below LaVine and Turner. I wouldn't be surprised if a couple of those guys make the jump this year though.
