ibaka with the new distance record in the dunk contest i think. no one has ever been completely behind the line, at least in the nba dunk contest.
6'10" center doing what guards did.. I'd give him an 8. Seen it before, and he's much taller than those who did it before him. Look at the replay.. he barely got off the ground! Long arms saved him.. not that impressed.
I think Ibaka was further behind the line than anyone who has completed that dunk. That was impressive.
