Many people criticize his poor defense, including his senior Gan Guoyang, who mocked his bad defense during the game and told him to train hard.
But Nash doesn't take it to heart. He never thinks his poor defense is a problem. As a Point Guard, what matters most is offense.

This personality has its pros and cons. The positive side is that he can shield himself from negative information and focus on what he believes is right. Once the path is correct, the results can be extraordinary.
The negative side is also obvious. The proverb says, 'A wise man listens to advice,' but believing only in oneself can easily foster a stubborn and self-willed character.
When his decisions involve only himself, being stubborn may not be a bad thing, but once more people are involved and the scope is widened, trouble follows.
