The draft is so watered down thats it really hard to find a sleeper anymore.
That said a sleeper to me is a 2nd rounder who sticks in the league. USA player - I'd go with Mario Austin because he is tough inside and can rebound and International player - Maciej Lampe who is a tweener (not big enough physically for PF but not quick enough to guard SF) but who can shoot it, is young and is 6'11.
Draft bust: CHRIS BOSH - to me he is the perfect bust candidate because he isn't and won't be big enough or nasty enough to play PF and he isn't fast or quick enough to guard the 3. He has talent but no NBA position IMO.
