First Things First What is a Basketball Screen in BasketballFirst Things First: What is a Screen in Basketball?

So, what is a screen in basketball? Good question. Because some players don’t understand the concept of the screen, it can be challenging to get them to willingly put their bodies on the line and set a screen.

The primary purpose of a screen is to create space for a teammate, while on offense, by using your body as a barrier. This barrier creates separation for your teammate from his defender. Different players have different ways in which they call for screens or advise their teammates that they are giving them one. You can discuss with your teammates how to signal for a screen in basketball games. You can agree on a variety of signals.

A screen can be set for the player who has the ball. This type of screen is called an on-the-ball screen. An on-the-ball screen can be utilized by the ball handler to get enough space to dribble penetrate, take an open shot, or get into space to make an easy pass.

Even though an on-ball screen is set to create space for the ball handler, for it to be most effective, the ball handler needs to make contact with the screener while he goes around the screen. This prevents the defender from penetrating the pic easily.

Multiple plays can be developed out of an on-ball screen. As we mentioned, it opens up a lot for the ball handler, but it also allows for the screener to get into scoring positions as well. One of the most common plays in basketball is the pick and roll. This is when the screener rolls to the basket after he sets the screen for an open pass and often an open layup or short.

First Things First What is a Screen in Basketball

If a screener is a capable shooter, he can also pop out to the perimeter for a shot after the ball handler uses the screen. This play is known as a pick-and-pop. These are two of the primary offensive plays that the screen can be used to create. Many others are utilized by different coaches and players.

The pic can also be set off the ball; this is known as an off-the-ball screen. Off-the-ball screens have the same basic concept as an on-the-ball screen. They are used to create separation for one player and his defender. When the screen is set, the player who the screen is set for should run and the rub shoulders with the screener to close out the defender.

After setting the screen, the screener has multiple options. He can open outwards for a shot, he can move on to set another screen, or he can also roll to the rim. These are just a few examples. There is a myriad of other plays that can be done from this. Due to the multiple options opened up by a screen, it is an extremely useful tool that players and coaches should take full advantage of in games.

One fundamental of the screen is to create contact with the defender so some players may be unwilling to put their bodies on the line for this. Pics also mean that you may not be the first option for the next pass or shot. Because many players want to take the next shot, they could also be reluctant to set the screen. Coaches often find these two challenges difficult to overcome when trying to get younger players to be willing to set pics.

You need to know that a screen does not have to be set by one person, multiple persons can set a screen, or multiple pics can be set at the same time. Even though numerous persons can set a screen, it is illegal for them to interlock arms or legs while setting the screen.

Why Do Players Set a Screen in BasketballWhy Do Players Set a Screen in Basketball?

There are multiple reasons why players set screens in basketball. The reasons for the screens will depend on the plays that the coaches want the team to execute. It could also be dependent on the culture of the team while on the court.

Some teams play with the natural instinct of getting each other open. The best way to do this is to set a screen. If you play on a team with this culture, you know what we are talking about. You and your teammates would always be setting screens to free up yourself and each other for open passes, shots, and dribbles.

Coaches often create plays that require screens to get one or multiple players open for shots or layups. A player can set an on-the-ball screen for numerous reasons. An on-the-ball screen can create space for the ball handler to shoot, pass easily or dribble to the rim. A player can also set an on the ball screen to force the defenders to switch. Switching could then create a mismatch for either the ball handler or the screener.
Another reason why an on-the-ball screen can be set is to allow for the screener to get an open shot or an open layup after they role or pop. Players can set off-the-ball pics to get their teammates free, create mismatches when the defense switches, or to get themselves open if both defenders follow their teammates.

Whatever the reason why a screen is set, if the defense does not react in time and appropriately, the offense will often get a basket. One essential thing that’ coaches try to do to make sure that their team is not severely affected by the screen is to put players on the court that are capable and versatile defenders. This tactic allows for the team to switch easily whenever a screen is set.

You must know how to set a screen correctly in basketball. If a screen is set illegally, it will result in a turnover once the referee makes the call. There may be different ways that players set pics, but the basic concept is the same.

How Do Players Set a Screen in Basketball

To set a screen, a player should use their body to form a blockade in the path a defender would take to keep up with their teammates. When the player sets the screen, it should be set so their legs are shoulder-width apart, and they should not be leaning forward.

In most cases, there will be contact between the screener and the defender, so prepare for the contact by protecting areas of your torso and your groin that could get hurt. The space between the screener and the defender is also vital.

The general rule of thumb is, if the defender cannot see you, you should be at least one step away from the defender. This can be closer if the screen is placed in the defender’s field of vision and could be further if the defender is moving.

If a screener moves in a way that will affect the uncomming defender’s speed, quickness, rhythm, or balance, then the screen will also be considered to be illegal. If the screener grabs or holds the defender, the screen is illegal.
