What is mechanical proficiency.
In tennis the form that we have on our strokes is really the mechanics of tennis. In tennis that form indicates whether we were will perform as a high-level player or intermediate player or advanced beginner player or even a beginner. so proficiency is a byproduct of mechanical correctness in tennis. so that’s why coaches when they teach they teach mechanics before they teach tennis tactics and strategy. Tennis without form can not produce consistency, so why worry about strategy.
