A wide stance keeps you low on the ball on return of serve. Yes, if the ball is within your reach or stride. If not, you will be in no position to return a serve offensively. What is wrong with a low stance in a defensive return of serve?
Well, in most levels of play it is effective. As you march toward the top of your game, you must decide whether to be a puncher or counter-puncher. If you hit ceiling balls and your opponent hits ceiling balls one of you has to shoot sooner or later. The shooter is the puncher. The one waiting for a mistake is the counter-puncher. Both styles can win, but my experience is given equal skill level, good punchers take out counter-punchers!
A counter-puncher has to have a mistake to feast on. That puts them in a position to win vs the puncher but as the offensive minded player evolves, they dictate the game! I see this theory proven time and again. Giving the offensive opportunities to someone else in a close match often leads to defeat.
Back to the wide stance. Ever watch a cat jump up on a table? I have never seen them get a wide base to move after a mouse! Become a cat, not a middle linebacker. Pounce on that serve like a cat on a mouse instead of lumbering toward it by starting in the wide stance position.
