skill wise, Lin is a far superior passer right now than TP was at this stage of his career. Parker also had Duncan and Ginobili who played around his game to make it work while Harden expects the opposite of Lin.
i think he's being too generous on both sides on this
Parker's main case was stats. if you believe him, that's what you go by. stats don't tell the skills or on the court game so you can't use them for something like this.
