question: Do defensive positions differ from offense?
article: Water polo
candidates: Defensive positions are often the same positionally, but just switched from offense to defense. For example, the centre forward or hole set, who directs the attack on offense, on defense is known as "hole D" (also known as set guard, hole guard, hole check, pit defense or two-meter defense), and guards the opposing team's center forward (also called the hole). Defense can be played man-to-man or in zones, such as a 2–4 (four defenders along the goal line). It can also be played as a combination of the two in what is known as an "M drop" defense, in which the point defender moves away ("sloughs off") his man into a zone in order to better defend the center position. In this defense, the two wing defenders split the area furthest from the goal, allowing them a clearer lane for the counter-attack if their team recovers the ball.
