True, taking more shots does equal more points, good for you!
Plus you can't overlook Tim's years playing in college, plus the fact KG has had the whole summer to rest almost every ing season, compared to Timmy making it to the 2nd round every year(not sure if he has ever been bounced in the 1st round, but I highly doubt it). When you have the best big man of this era on your team, you don't need to score 23 pts a game. Plus, Manu has been on star teams his entire career, he's never had to been the man, and I bet Tracy has played more withought Yao than with, unless they've been injured more over the same period of time than not.
