And it isn't illogical for Westbrook to get a great deal of plays called for him given his touch tendency. Run that back and tell me how it pans out. And for me can you give Westbrook only ISO plays that involve point guards. (Ie. pick solo, 1 go, things like that.)
I would definetly like to know what your findings will be for that.
