In basketball, there are two main defensive strategies: man to man and zone. The most common type of zone defense is the 2-3 zone. In this article, we're going to discuss the origins and the specifications of the 2-3 zone defense.
The 2-3 zone is often used when the defensive team believes they may have an athletic disadvantage. This disadvantage can be easily exploited in man to man defense because, in theory, the offensive scorer only needs to get past one man. The 2-3 provides more structure to the defense as a whole and makes it easier to defend against players who like to drive.
Zone defense is a defensive system in which a player is designated to guard a specific area rather than a single player, which would be a man-to-man defense. Zone defenses are most often used to guard against a specific tactic, such as corner threes or driving into the paint. For some, zone defense can be easier to play than man-to-man as there is less responsibility involved in guarding a specific area rather than following a single player all around the court.
In a 2-3 zone, two players (usually the two guards) play at the top of the key, while the other three defenders take the lower post, midrange, and painted areas. The job of the "top" (two) players is to prevent the ball-handler from entering the lane and to close out on three-point shots. The "bottom" (three) zone defenders are responsible for protecting the paint, closing out on wing and corner shooters, and shifting to ensure help defense.
The 2-3 zone defense is obviously not the only zone defense in basketball. Popular examples of other zone defenses include the 3-2 zone and the 1-3-1 zone. The 2-3 is the most common zone defense, however, due to its simplicity.
Even though the 2-3 zone is one of the most common zone defenses, it is rarely used at the higher levels of the game. This is because there are simple, well-known strategies to counter the zone defense.
Another common counter to the 2-3 zone is getting the ball in the center of the floor at the top of the key, usually from a pass. Doing this usually draws the attention of the top two defenders, as well as the center defender. This disrupts the defense and usually allows a cutter an easier path to the basket.
Finally, overloading one side of a zone allows the offense to gain a numbers advantage. Overloading a side forces some of the defenders to shift away from their normal zones and disorient the defense.
