The key difference and area of improvement: where John pulls up and settles for a midrange jumper, Parker keeps his dribble alive and constantly probes the space between defenders, never allowing them to settle into a comfort zone. John would need to work on his handle even more than his jumper. Interesting because I think he sees this as an area of strength for himself, but I forget who mentioned the Chinese pingpong player anecdote but it seems to apply here.
The Chinese have long held the Olympic gold medal in Ping-Pong. At the 1984 Olympics, when they again captured the gold, the coach of the Chinese team was asked by a reporter, "Tell me about your team's daily training regimen."
"We practice eight hours a day perfecting our strengths."
"Could you be a little more specific?"
"Here is our philosophy: If you develop your strengths to the maximum, the strength becomes so great it overwhelms the weakness. Our winning player, you see, plays only his forehand. Even though he cannot play backhand and his competition knows he cannot play backhand, his forehand is so invincible that it cannot be beaten."
Quoted here for instance.
This is something that players like Tony Parker and Steve Nash have done. Nash said he knew he was never going to be the quickest player on the court but as a year round athlete growing up (bball, soccer, rugby) he knew he had great stamina, and worked to become the best conditioned player on the court so that he could stay in motion constantly, outwork and outrun you at his top gear, and to get open he learned to groove his shot so that he could take it the split second he was open instead of trying to outjump you. Practice his strengths.
Parker too, quick yes but his next-level skill has always been his heads-up dribble and control. Quick read-recognition skill. Pops genius was to recognize this as his primary asset to the team and drill him in constantly staying aggressive and keeping his dribble alive. I recall early on Pop would rip into him if he ever got passive and allowed the defense to dictate what he was doing or where he was going. As an 18 year old kid Pop would not allow him to get nervous or tentative, he was more nervous about the guy on his bench than the opponents. Head up, eyes alive attack attack attack make them adjust to you, not vice versa. And that's what I want from John.
John has the eyes, has shown a good dribble, wins with great speed and vision more than an outside shot. If we're trying to take full advantage of what he does well, yes I want him to have a change-of-pace gear, and a grooved shot and a three ball, but more than anything I want him to have full control off the ball even when he is going full speed through traffic. Once he gets that down then he's even more of a load for defenses to handle, and refs will give him the benefit of the doubt on his attack instead of whistling him for offensive fouls as they did his first couple years in the league.
