I don't know anyone who agrees with that either. What I do know is that every draft guru that I have seen talk about the question wouldn't take Maitan over most of the guys taken in the first round because he's 16 years old and unproven. That's not a slight against Maitan.
What makes Moniak "proven"? None of the guys in the draft are proven. Any player in the Draft/IFA could be a bust.
