scout 2 is an idiot. embiid is not a true 7fter. hakeem was 6ft 10. so real difference between young hakeem and embiid is probably an inch at best.
anyway, health is a legitimate concern. just look at the 7fters around the league - bynum, oden, lopez, and bogut. it's a huge gamble.
wiggins - his lack of aggression is a huge concern. you want your #1 pick to be a ferocious tiger not a teddy bear. temperament is important in this league.
Don't know about Hakeem but:
