he's better because of 8 points per game more, less rebounds, and less blocks? take into consideration the age difference here, also camby provides leadership and veteran morale, something yao is far, far from providing.
on a side note, i despise people who try to own a game with only one player. people who use kobe, lebron, tmac, etc and nobody else in a game can suck my dick. it really ruins the game.
