The biggest difference between Yao and Qi is Yao's more developed legs and lower body. Yao was an Anchor. Qi may put on weight but I don't think he will ever have the Tree Trunk legs Yao had Qi could compensate by developing his three pointer more or some 'quick' post moves. YAO was amazing on the block but Qi could be quicker but IT IS GOING TO TAKE A HELL OF ALOT OF WORK AND DEDICATION on Qi's Part Hell . . . Every center on our Roster could learn from Yao Rocket River
