Yes his jumper fell off after 2013, but he became a pick and pop player in the Parker-led offense. It was even acknowledged by Pop that he adjusted his game.
Why do you believe he was spoon fed most of his points?? That's bull , man. I can understand if you didn't watch basketball 15 years ago, but know that you've been misinformed. He was a terrific one-on-one scorer in his prime, and he quarterbacked the offense from the post. The entire offense revolved around him. He was a great passer out of the post, and he even had an excellent dribble-drive game in his younger years. He was the opposite of a one-dimensional player like Amare Stoudemire, who actually was spoon fed most of his points by Nash.
