Gan Guoyang's advice to Nash was not good at all, even quite misleading.
And Nash didn't expect that the first time the senior brother played with him, he'd propose such unreliable advice.
In modern basketball, the offensive capability of a Point Guard is much more important than defense, especially as the NBA court space becomes larger.
The defensive benefits of a Point Guard are inherently low; a Point Guard known for great defense can, at most, guard the first and second positions, along with some help defense tasks.
Other critical defensive tasks such as rim protection, backcourt rebounding positioning, and switch delay are often not feasible for Point Guards due to their height limitations.
In contrast, the third and fifth positions have the highest defensive benefits; the fifth position is crucial because it safeguards the important region under the basket, while the third position is versatile, capable of handling tasks across all five positions.
