^that is because Nash has better court vision than Blake. I know that may sound weird when it comes to being turnover prone but it really is that simple. When Nash penetrates he passes to where a person "should" be but unfortunately most times our guys aren't moving to the right spots. When Blake penetrates he is looking for guys where they are and usually gets the ball to them there. Blake is use to playing with guys who don't move (mainly cause of everyone watching Kobe play) so he has better timing with guys. Nash is use to guys who understand cuts, pick and rolls and backdoor movement like Twan. Now, put them with Dwight and you see Blake is more suited because Dwight still is very raw when it comes to setting proper screens and knowing when/where to slip the screen. Nash uses the screen to perfection while Blake uses his quickness more. Each are great at getting the ball to a player but they go about it in different fashion. Right now Blake is more effecitve but that has more to do with guys not understanding the "chess game' that Nash plays in my opinion.
