What is an NBA Collision Zone? Why isn t there an international competition?

The NBA collision zone is a reasonable collision area, and in 2010, FIBA also added a no-collision area (that is, a reasonable collision area) to the rules revised by FIBA, and there will be a collision area in international games in the future.

NBA Reasonable Collision Zone: In the NBA court, the center of the basket is the center of the circle, and the semicircle with a radius of 4 feet (meters) under the basket is called the reasonable collision zone. Standing within the arc, a defensive foul may be awarded as long as the defender makes physical contact with the offensive player.

In addition, the defender can stand up in advance, and if the offensive player touches the defender with his body, the offensive player will be sentenced to hit someone. In a reasonable collision zone, when the opponent is attacking, a defender will not be whistled for a foul if he jumps vertically, but a defensive foul will be whistled if he does not jump or jumps after moving his body to make physical contact.

NBA Reasonable Collision Zone Rules:

1. The reasonable collision zone is only applicable to the assistant defender (the defender who is not the active defender of the ball).

2. The offense must have started outside the low defensive zone, otherwise the co-defender does not need to consider being blown and blocked;

3. The main marker of the offensive player can make offensive fouls no matter what position he is in contact with the attacker;

4. In the fast attack, all defenders are regarded as co-defenders;

5. Even if he is in a reasonable collision zone, if the assistant defender falls vertically when trying to block, then he will not be blown to block;

6. If the offensive player and the assistant defender make contact in a reasonable collision zone, but the attacker uses unconventional knee or foot movements, then the offensive foul may also be whistled.

FIBA Collision Zone: The FIBA Bureau meeting held in Beijing in 2008 adopted new rules that came into effect on October 1, 2010. Under the basket, a reasonable collision (no ball hitting) semicircle is added, and the inner edge of the semicircle is meters away from the center of the basket (projection on the ground); The rule also changes the restriction zone, i.e., the three-second zone, to a rectangle.

When the rules for the Reasonable Collision (No Collision with the Ball) Zone applies

1.Defenders must be in a reasonable collision semicircle with both feet at the same time. The edges of the semicircle are not part of the plausible collision zone.

2.The attacking player should break through the semicircle and attempt to shoot or pass the ball in the air.

The Reasonable Collision (No Dribbling) Zone Rule does not apply in the following cases, where penalties will be awarded in accordance with general rules such as the cylinder principle and the Dribbling Blocking Rule

1.All occurrences outside the zone of reasonable collision (no collision with the ball) also include the area between the semicircle and the baseline.

2.All the physical contact that occurs when scrambling for rebounds after shooting.

3.Any unlawful use of hands, arms, legs and body against both offensive and defensive players.

If I'm not mistaken, it should be the area outside the arc in the red three-second zone under the basket, as for why there are no international games, because the format is different!

The NBA's collision zone is a reasonable collision zone. In the smaller semicircle in the three-second zone. If a defender is standing in front of an offensive player and you don't blow an offensive foul.

FIBA has some differences from the NBA. It's like the NBA has a three-second zone and the NBA has a three-second zone... There are no hardware rules for this.

As people say, the NBA is flying from the outside and flying in the sky, and FIBA is the same as hand-to-hand combat on the inside, no, this is the consequence of the collision between the three-second zone and the reasonable collision. Pure hand fighting,I hope to help you 、、、 hope.。。

There is an area in the three-second zone, in which there is a collision who will not collide with someone and foul, FIBA and NBA have many rules that are different, for example, grabbing rebounds in the area where the basketball pop-up frame is not considered interference, so many NBA stars are very uncomfortable playing international games, which is also the reason why many players do not enter the national team.

Rational use of the body in ball control and pressing. For example, when the defender and the striker accelerate to catch up with the ball at the same time, the bodies of both sides will definitely squeeze together and collide, and there will always be some instinctive movements in the hands, which is reasonable body contact. Another example is to use the body to lean on the opponent when grabbing a header, so that the opponent can't grab the point or even can't jump, this is not a foul, and it is considered reasonable physical contact.

But these are all about using the body with equal opportunities for both sides. If the opponent has already jumped and rushes the opponent with his body to lose the opponent's center of gravity, or knocks the opponent away when the opponent is already in possession of the ball, it is a foul. A player who tries to block an opposing player from touching the ball while covering the ball is not a foul within the meaning of Rule 12(3) because the ball is within the player's control and he may cover the ball as tactically necessary.

In this case, the opposing player can make a reasonable collision.

This is to prevent tall players from standing under the basket when defending, and when the opponent breaks through to the basket, the opposing center will inevitably be hit by the layup player, and international rules (such as the rules of the World Championships and the Olympic Games) say that as long as the defending side does not leave its own cylinder, the attacking team will be sentenced to hit someone. As a result, as long as there is always a defender standing under the basket on the inside, it is difficult for the offensive player to make a beautiful layup or dunk.

In the original basketball rules, there was no reasonable collision zone, but in order to encourage offense, especially the offense of outside players, and increase the spectacle of the game, the NBA added a reasonable collision zone.

It seems to be because of O'Neill.

It's not just the NBA that has a reasonable collision zone, all basketball courts have it, which is the free throw line, and it's close to the basket inside, and the one with the dotted line is a reasonable collision zone, and you don't usually squeeze people in.

The so-called reasonable collision is that.

There's nothing else to do, but if you break through with the ball and someone else comes to stop you and you fall, then he stops it.

The problem of blocking and ramming is like a car coming and you hit him in the middle of the road and you go to stop him and hit him, depending on who stands first.

The "no-charge area" = the "no-charge area" was introduced at the beginning of the 1997-98 season.

In the 1966-67 season, the league stipulated that interior players could not "stand" in the three-second zone for more than three seconds;

In the 1981-82 season, after Stern entered the NBA, the star-making movement began, stipulating that no ball-free people could be included, and the interior could be stationed in the three-second zone...

In the 1997-98 season, the league introduced a reasonable collision zone, where physical contact was not fouled (from then on, everyone saw O'Neal squeezing the opponent's dunk...

In the 2001-02 season, the league eliminated illegal defense (making the NBA go back to the pre-80s rules, when Russell, Chamberlain and other centers played, and allowed centers to be caught off the ball), and at the same time stipulated that interior players could not "stand" in the three-second zone for more than three seconds without anyone attacking the interior (this is the same as the rules established in the 1966-67 season), which is the so-called problem of dotted and solid lines.

Reasonable collision zones are only available in the NBA and are not available in FIBA games. It's the area within a small arc in the three-second zone near the rebound, which is added to add to the physicality and excitement of the game.

The difference between an offensive foul and a blocking foul is only a small point. If a defender gets stuck in the position before the offensive player and is hit by an offensive player with both feet on his feet, the offensive foul will be considered a defensive foul if he has not yet stood up or has too much movement.

Sometimes in an NBA game, it is difficult to tell whether a ball is an offensive foul or a blocking foul, and it mainly depends on the referee's blow. However, referees can only rely on experience and on-field factors, such as home and away, star players and other factors

Any player can defend in a "reasonable collision zone" if the offensive player is in a position that requires them to start, and physical contact between players does not necessarily mean that the defender has committed a foul. The referee must base his judgment on the usual defensive foul judgment. That is to say:

any player may be legally positioned within the "restricted area" ifthe offensive player receives the ball within the lower defensive box.

The three-second zone is the reasonable collision zone.

A small semicircle in the three-second zone. It's as simple as that.

There is a fox under the basket, and inside the fox is a reasonable collision.
