But the reason why guys like Danny Green are getting these wide open shots is because Tony Parker is the clear focus of their offense. He is their primary option and they run all their pick and rolls for him to either score or create for others. Tony Parker only had 6 points but he had 8 assists. If the stars aren't getting shot attempts then they should be getting assists by passing it out to the open guy. It's all about the role players playing OFF of the stars. That's the most important thing, not the absolute shot attempt numbers. It just so happens that the focus is on shot attempts particularly because Tyreke isn't Chris Paul or Rajon Rondo. "Taking away" shots and playing off of guys are completely different things, and it's foolish to lump them into one concept. Tony Parker could have only 3 FGA the entire game to Danny Green's 20, but I assure you that the Spurs offense will still run the same way on every possession, pick and roll for Parker to create for a Green open shot. There is ZERO chance that he would go for multiple possessions without being the driver of the offense, let alone just touching the ball like we saw happen to Tyreke.
So you're wrong. Cousins and Tyreke do have to take the most shots on a regular basis in order to force the defense to play them. I assure you defenses are perfectly happy letting Isaiah Thomas or John Salmons beat them on 1 on 1 created shots. Nobody would mind if your beloved Isaiah Thomas was simply hitting shots created for him but the fact is that most of his shots taken were selfish chucks. The reason why the Spurs get guys like Danny Green and Matt Bonner is because they don't demand shots for themselves and rarely take anything on their own. That's how the Spurs end up leading the league in assists/game. And you don't pay guys 8 million a year just to hit open 3s.
Or how about the criticism of Lebron James when he isn't aggressive, i.e. taking shots. He can have 10 assists and actually be playing a good team game but the team is at their best when he's scoring. What's the point of stars and superstars if you're not going to run your offense through them?
