Lee has improved offensively without a doubt. However, he is putting up bigger numbers here than he would on other teams because he is playing for D'Antoni and he does not have competition for time or touches at the center spot.
You want proof? Just take a look at any player who played under D'Antoni in Phoenix and their offensive numbers(Such as Shawn Marion, Boris Diaw, Nash, Stoudemire and more) and the dramatically lower numbers they put up in a different system. The only exception that I can find is Joe Johnson and that is because he gets the ball on every possession in Atlanta.
This is not a knock on Lee, or Chandler, or Gallinari, but it just the facts jack!
oohah
