I'll play.
Tony Parker vs Westbrook.
First, I hate games like this. You can't "choose a player" based on 5 stats, presented with no other information. Larry Bird is a top 5 player of all time. I'm guessing if you put his career numbers, like above, there are lots of lesser players that might appear to be better. But I digress.
I'd take Parker, if you are asking me who I'd rather build around. Would I say the Thunder would be better with Parker over Westy? No. Heck no. The Thunder, the way they are currently built, have to have a scorer like Westbrook. But SA wouldn't be better with Westbrook over Parker. Parker is a better fit for that roster.
I want my pg to be able to do a few things. Score efficiently (Parker blows Westy away in this regards), get the ball to the open man and start my offense, which will have scorers at the 2/3 spots, take care of the ball, and play solid defense.
Like I said, pull up a list of past NBA champions. In recent years, none of the teams that are winning titles are doing so with a pg like Westbrook. I don't think that is a coincidence.
