some TO standings from nba.com (turnovers per game)... zach is averaging 3.9 TOs in 34 mpg over 10 games, good for 6th in the league. only people above him are guards. players below i'd consider comparable (all of the forwards and big men after ZR, most of whom play marginally more minutes than him):

yao 3.5
melo 3.4
josh smith 3.2
gerald wallace 3.2
jermaine oneal 3.1
kaman 3.1
odom 3.0
dwight howard 2.9
shaq 2.8

addendum: skipping to lower down the list to guys who are probably equally talented on offense and probably used similarly

KG 2.5
boozer 2.3
duncan 2.3
