How does the NBA designate which referees to blow penalties for games?

There are three referees in total, and the division of labor is clear and reasonable.

A referee is placed on the baseline, one on the weak sideline, and one on the middle line, like a triangle offense, basically standing in an equilateral triangle, when the ball is on the outside, the sideline referee stands on the extension of the free throw line as shown in the picture, and when the ball falls into the low post, he also has to stand down accordingly. Often, the division of labor is that the weak-side referee focuses on the off-ball person, the baseline looks at the low post and counts three seconds, and the mid-line referee watches the ball and follows the fast attack. The field of vision of the three referees should be said to be quite reasonable, and there is basically no blind spot compared to the double referees.

The NBA generally has three referees on the court, consisting of two assistant referees and one head referee, and the purpose of this is to make a fair decision. The referee is usually on the baseline, and the two assistant referees are usually on both sides of the court, so that you can better observe the dynamics of the players. When a penalty is disputed, the three referees will watch the replay of the match before discussing the outcome of the decision.

The NBA will make a roster based on various aspects, and from these lists, the final personnel will be determined based on the cooperation of these referees. Generally, referees also have a relatively regular rotation to strengthen their cooperation with each other. There are some top referees who can adapt to the style of play and the team style is more, and the players are not dissatisfied, which is the so-called famous whistle, and will be a firefighter in all games, and which game needs to be ranked **.

There are 3 referees in the NBA, two sideline referees and one baseline referee, divided into one referee and two deputy referees. Together, the three of them maintain the fairness of the competition. If there is a dispute between referees over the whistle, the referee will use a replay of the match to determine which referee should be heard.

NBA officials generally have three referees, one on the left and right sides of the court, and one on the bottom line, to ensure that the referees can see all the actions of the players on the court. The referees on the left and right sides usually have a player near the midfield, ready to follow up when a player steals a fast break.

In the NBA arena, the referee's is also graded, and the referee who generally stands on the bottom line is the biggest referee, and he generally blows free throws, if his vision is not seen, the other two referees need to blow out. 186, both referees are on the edge and can run with the players at any time. In this way, the fairness of normal games is guaranteed.

Each team in the NBA has its own referee, and its own referee will definitely not appear in its own game. The selection of referees is based on the technical characteristics of the teams and the importance of the game. For example, some referees have tight penalty scales, some are loose, and some encourage physical contact with players.

And in the playoffs, especially in the finals, the most experienced referees will be selected to blow the game.

What kind of behavior can be ejected by a referee in a regular NBA game? Everyone knows that the NBA is one of the best sports leagues in the world. It is one of the four major professional sports leagues in the United States, so its rules and regulations are also very strict.

Therefore, many serious fouls in the NBA will be blown out by the referee as a "technical foul".

So what kind of behavior will be blown by the referee as a "technical foul". Let's summarize it together. Technical foul one:

When defending an attacking player, aggression on the shoulder and above, such as holding the neck, pulling the shoulder, hitting the head, etc., is often whistled as a technical foul by the referee. Attacking the attacking player's shoulders above the shoulders is often a very dangerous act, which often results in very significant and serious injuries to the attacking player. These are all vital parts.

Therefore, this will be considered by the referee to be extremely risky behavior.

Technical Foul 2: Some players and coaches will disagree with the referee's decision. They will verbally abuse and complain about the referee's behavior.

These actions can cause the referee to believe that his authority has been greatly challenged and hurt. Therefore, referees often blow "technical fouls" for players and coaches who have been complaining about their decisions.

Technical Foul 3: After your team has completed the offense, your player cannot touch the basketball again. Touching the basketball will be considered as interfering with the normal game and will be considered a violation of the fairness and impartiality of the game.

Because touching the basketball after the offense is over, there is a high risk of deliberately delaying the game. Therefore, this is also considered a technical foul.

Technical Foul 4: Serious fights and brawls between players and players. This behavior often creates situations that disrupt the normal order of the game.

And it will seriously endanger the health of other players. This would also be seen as a serious breach of public safety and order. Therefore, this is a serious act of jeopardizing the game, so it should also be considered a technical foul.

It's also easy to understand.

Be sure to note that insulting the referee, headbutting the referee, or throwing something at the referee, as well as verbally hitting the referee, disobeying the referee's decision, etc., will be expelled by the referee!

First, throw something at the referee, second, insult the referee, third, put the referee on his head, fourth, disobey the referee's decision, and fifth, provoke with words.

In fact. The main penalties that are blown by the referee are fouls and violations.

Like walking. A second dribble out of bounds or something is a violation.

Fouls are mainly divided into offensive fouls and defensive fouls.

As far as FIBA rules are concerned.

The offensive foul is mainly to take away and hit people.

Cover fouls. Elbow strike.

Pushing people, etc. There are relatively many defensive fouls.

But it can also be divided into thugs in general.

Push Oak Lady. Blocking (many pushers can be counted as blocking), etc.

Actually, to put it bluntly.

A foul is committed through improper physical contact.

It's your own side that profits.

The main criterion for judging is:

Whoever takes the initiative to invade the other party's cylinder.

And then there's the technical offense.

This one. It is generally very obvious (technical fouls do not count towards one's own fouls, which means that four fouls in a game and then another technical foul will not be whistled off).

If the situation is serious, the referee will be punished. NBA referee Crawford is a case in point.

In 2007, Crawford's whistle caused a huge controversy. At the time, Crawford was implementing a zero-tolerance rule with Tim Duncan, and during a game between the Spurs and Mavericks, Crawford ejected Duncan for insulting himself because he was sitting on the bench and laughing. After the incident, NBA executives investigated the matter and decided to suspend Crawford indefinitely, and Crawford missed the 2007 playoffs and Finals.

Stern's assessment of Crawford was that he "lost the judgment he should have as an NBA referee."

In Game 4 of the 2008 Western Conference Finals, the Lakers visited the Spurs. In the final moments of the game, Lakers player Fisher violated a shot by former Spurs and Rockets player Brent Barry. If Crawford blew the whistle at that time, then Barry would have killed the Lakers with free throws, but Crawford, as the referee closest to the incident at the time, chose to ignore it, and finally the Lakers eliminated the Spurs 4-1, and the NBA apologized for the incident afterwards.

What do NBA referees do if they make a "misjudgment"? After reading it, it was unmistakable!

It should be because they have already been sentenced.

No one could have judged on the spot, and it was only after the fact that we found out. However, this is not usually the case.

Yes, it depends on the seriousness of the matter.

The more famous ones are recently.

Joe. Joe Crowford, bald, with a relatively large head, does not look old but is actually not young, with nearly 30 years of experience in NBA law enforcement His father was also a famous NBA referee.

In the regular season, because Duncan laughed, felt that he was contemptuous of himself, and sent him off for 2 consecutive technical fouls, the NBA officially banned him indefinitely, and Crawford said that he might retire and no longer enforce the NBA.

First of all, you will definitely be sent off with a red card, you will not be able to participate in this game, and then you will be given a fine.

This game is definitely not playable, and there may be a risk of a ban and a fine. The specific decision should be determined by the situation at the time.

That is directly a penalty for being sent out of the game, and there will be a ban, and playing referees is absolutely forbidden in the NBA, which will make this player banned for a long time.

If a player hits a referee, he will be ejected from the game by the referee on the spot. Because this behavior of the player is a malicious act of serious disrespect to the referee, and the player will also be banned and fined after the game.

1, 3 people.

2, there is no division of labor, the referee follows, and the deputy referee runs on both sides.

3. There is a set of professional gestures for gesturing, indicating the direction of the foul hand, pointing to which side is the player of the basket who fouls, and then reporting the number to the technical desk.

4,3 referees have almost equal powers, there is no division of labor.

5, the standing position was said in 2.

6, not necessarily, depending on which referee blows the foul, the foul is the left hand into a fist, straight over the head, the right hand straight palm down, five fingers together. Coupled with the specific action, it indicates what the specific foul is, just like inserting the waist to signal blocking, holding the wrist of the right hand with the left hand is to indicate the beater, and the hands are pushed out like playing Tai Chi to signal the pusher.

If it is a violation, only the left fist is extended above the head, and the right hand is not moved, plus the number, and the specific foul matter, such as the hands wheeled like wheels, indicate walking.
