One of the most common ways that defenses are taught to defend the football is with a zone defence. Zone coverage allows teams to use more players in the defensive backfield without having to worry about covering every receiver. There are several different types of zone defenses, but they all rely on the same concept: defenders drop to their zones and watch the quarterback for clues on where he intends to throw. This type of coverage can be effective but it is also a dangerous game for secondary members that do not have the discipline to stay where they are supposed to be.
There are many different ways that defenses can set up their zones, but the most popular is to have two players in the deep zones and five in the underneath zone. This type of defense can prevent a lot of the quick, short throws from becoming big plays. Some teams may even add more than four pass rushers into the mix to try to force the quarterback to make quicker decisions.
Another common way to set up a zone defense is to have two safeties in the deep zones and four players that play the underneath areas of the field. This can help to protect against any deep, long plays that the offense might try to run.
This kind of coverage requires good communication and teamwork for the defenders to be successful. Each defender has their own area that they are responsible for and they must communicate with each other about the types of routes that the offense is running. They must also be able to read the speed and direction of each route so that they can adjust their drops accordingly.
In most cases, defenders in zone defence are taught to take aiming points or landmarks into account when dropping. This is because a lot of zone coverages are split into thirds and the defenders will usually get passed off to the next deep player after they cross a certain hash mark on the sidelines. Taking these into consideration when dropping can help defenders to be more consistent with their positioning.
Many defenders in zone defence will also be instructed to “shuffle across” when they are in the middle of their zones and it is the responsibility of the defenders to stay close together at all times. This can be done by putting a high emphasis on the physicality of the game and making sure that the defenders are not getting too far apart from each other.
Many players will also have a preference towards playing man marking over zone defence, but this is not always the case. There are some situations that can be played better with man marking, such as when an opponent is running a pattern that requires the defender to cover them directly. In these situations, a defender might want to switch to man marking and cover the receiver directly. This is often considered to be more efficient than shuffling across and can help the defenders to win more one-on-one battles.
