Tyson Chandler
Dwight Howard
Amare Stoudamire
Lebron James
Javele McGee
Charging 100 racks a pop to teach these fools how he "mastered" the post game. I think all the above mentioned players have gotten worse in offense.
Who has actually benefitted from his teachings?
Look at the players you listed. Except for Lebron they'e either stiff as hell (Chandler, Amare, Dwight) or just not gonna be working on their game that much (Dwight, McGee). One month with Dream ain't gonna change that. Dwight spent years with Ewing down in Orlando, and years win Houston with Dream and Kevin "Torture chamber" McHale, and he's still the same player.
Bron's the only one on your list who had the physical skils and the work ethic to improve, and he did.
