So would I. And I would wager the stats would be about the same for Parker but worse for Paul.
Why?
A healthy chunk of Paul's game is the P&R lob pass & dunk. Paul is going to miss having Chandler there to get those 3-4 easy gimme dunks every game. Those 6-10 surefire points every game really made those two players special together and made them appear better than they really are. It will become evident more than ever this upcoming season. Without Chandler to make Paul look great, he is going to take a step back. And without Paul to spot him many easy dunks every game, Chandler's days as a starting quality center are as good as done.
Okafor I think will be lucky to get 1 lob pass per game. Duncan would probably be lucky to even see a handful of those patented Paul lobs in a whole season.
Paul's game was perfectly matched with Chandler's, and I mean absolutely perfect. One could argue that Paul helped Chandler statistically. But on the other side of the coin, it was also Chandler that helped Paul. Now that the duo is broken up, both individuals will be < the sum of the two.
On the other side of the coin, you have Parker and Duncan, both of whom are very well suited to each other (each knows the other so well and play off of each other brilliantly), and will still be playing together unlike Paul / Chandler. In this light, I don't think Chris Paul would be better than Tony Parker in the spurs system... his style doesn't compliment Duncan at all.
So, in closing.. you are just... wrong.
