He will be 19.5 draft day this year, if the November 10, 2006 birthday I found is legit.
He should absolutely enter and go through pre draft this year as he gets a few freebies before he has to go, but he's a bit of an unknown for the draft as far as measureables and not playing at those elite camps. Is he a legit 6'7" ? How far off is he if he isn't? What's his wingspan?
I'm not ruling him out to maybe go this year because if he finishes hot and God willing has a great dance, teams might want him, but at this point I can't even venture a guess to his ceiling or floor in the draft
