NBA history

1896, the first American basketball organization, the National Basketball League (NBL), was established, but the rules and organization of basketball were not perfect at that time. Usually, a player can represent several teams in a season. After several seasons, the organization existed in name only.

1946 On April 6, the American Basketball Association (BAA) was founded by Walter A. Brown, the owner of Boston Garden in the United States. Brown first proposed high salary system and contract system, which became the two cornerstones of modern professional basketball. High salary system means that professional basketball must have strong financial support in order to keep the game at a high level, attract audiences and survive. Contract system means that a player can only sign a contract with one club and set up a player reserve system to prevent players from leaving the team suddenly and causing losses.

1949, with Brown's efforts, two major American basketball organizations, BAA and NBL, merged into the National Basketball Association (NBA). Brown also became the founder of the later famous Boston Celtics. When the NBA was founded, there were 17 teams, which were divided into three divisions. The Minneapolis Lakers from NBL won the NBA championship in the first season with the help of george mikan, the No.1 center in the United States, who is 2.09 meters tall. From the beginning of the 1954-55 season, only the east and the west were left after the natural elimination of the NBA. Among them, the eastern alliance is divided into Atlantic region and central region; The western alliance is divided into the central and western regions and the Pacific region.

1952, in order to limit the scoring ability of the first center McCann, the NBA expanded the width of the 3-second penalty area under the basket from 6 feet to 12 feet. In 1960s, because of the appearance of another super center, Chamberlain, the NBA expanded the width of the penalty area to 16 feet.

Because NBA teams often use delaying tactics when the score is ahead, the game can't attract the audience. From the season of 1954- 1955, the NBA began to implement the 24-second system, that is, the offensive time of each team should not exceed 24 seconds. 1973, CBS bought the right to broadcast NBA games for three years for $27 million, which made NBA games appear on TV for the first time. However, because there were no conditions for live broadcast at that time, only videos could be played.

1967, the new basketball organization ABA (American Basketball Association) was established, with George Macon as the first chairman. Aba adopts red, white and blue basketball, implements the three-point system of long-distance shooting, and holds a dunk contest every year. These measures are not allowed in the NBA. However, due to poor management, ABA was annexed by American NBA in 1976, and since then NBA has formed a monopoly on American basketball industry.

From 65438 to 0979, the NBA began to implement the 3-point long-distance shooting system. In order to avoid the disparity in strength between teams, the NBA has established an annual "NBA rookie selection and distribution system", which ranks college students who graduated in that year according to their level, and then each club selects them in turn according to the final ranking of the league in that year. The latter ranks first, and each team can only choose one in each round, thus ensuring that the team with the weakest strength can get the rookie with the highest level, while the weak team that chooses the new star will often be reborn in the new season. In order to prevent rich teams from monopolizing high-paid star players, the NBA has set a total salary limit for each team. If you spend a lot of money to buy a star, you can't buy other excellent players. This system ensures that the best stars are evenly distributed in each team, which makes the strength of each team very close. If "high salary system" and "contract system" are the two cornerstones of NBA, then "rookie selection system" and "salary limit system" ensure the tension and excitement of NBA games, and the unpredictability of the games attracts many American fans to the basketball court.

The NBA league also implements the transfer system, and NBA players can't buy or sell, so they can only be replaced by people. From the beginning of the season to 9: 00 pm on Thursday 16, the team can exchange players freely. Since then, all the players have been "frozen" until the end of the regular season. NBA transfer is the exchange of people and contracts.

Blow out the 58th birthday candle, and the cake is the latest version of Charlotte Bobcats in 2005 NBA, which has become another cherry on the butterscotch. Thirty, not the old tree rings with grain precipitation, but a new time and space for memory expansion. From 1946 to 2004, the bar code of the team went from 1 1 to No.30, which was unprecedented in the NBA.

Eastern alliance

NBA member

Atlantic Division: 76ers, Knicks, Nets, Celtics, Raptors.

Central Division: Pistons, Pacers, Cavaliers, Bucks and Bulls.

Southeast Division: Heat, Magic, Wizards, Eagles, Bobcats.

Western Union:

Northwest Division: Timberwolves, Nuggets, Jazz, Trailblazers, SuperSonics

Pacific Division: Kings, Lakers, Suns, Warriors, Clippers

Southwest Division: Spurs, Rockets, Mavericks, Grizzlies, Hornets.

The sixth division highlighted regional confrontation. With the addition of Charlotte Bobcats, the number of NBA teams has reached 30. There has been controversy about the rules of seed ranking in the playoffs. After discussion by the league management, it was officially announced on August 3, Beijing time that the existing rules of seed ranking in the playoffs will be changed from next season.

There are 30 teams in the NBA, which are divided into two major divisions, East and West, and each division is divided into three minor divisions. The East Division is the Atlantic Division, the Central Division and the Southeast Division. The Western Division is divided into Southwest Division, Northwest Division and Taiping Performance Division.

The new seed ranking rule is that the top four seeds in each division are composed of the team ranked first in each division and the remaining teams with the best performance, but the top four seeds are ranked according to their respective achievements.

The previous ranking rules of playoff seeds were obviously unreasonable. According to the previous ranking rules, in each division, the top three teams in each division are the top three seeds in the East and West Divisions, and their rankings are arranged according to their respective records. The second place in a certain division, even if its winning rate exceeds the first place in another division, can only be ranked in the fourth seed in that division.

This ranking rule was criticized last season. The two strongest teams in the Western Division happen to be San Antonio (Anthony News, Anthony speaks) and Dallas Mavericks, both in the Southwest Division. However, according to last year's playoff seed ranking rules, the Spurs were the first seed, while the Mavericks were only ranked fourth, although their winning percentage was much higher than that of the top players in the Southwest Division, Denver Nuggets and Phoenix Suns. So the two best teams in the West had to meet in advance in the second round of the playoffs. In the end, Dallas Mavericks won the Spurs in seven games and advanced to the Western Conference finals.

Note: As we all know, NBA is the abbreviation of National Basketball Association, but according to some active players, such as shaquille o'neal, NBA has another explanation, that is, it is nothing but actors.

(3) Foul and its punishment

1. A technical foul is a punishment for unethical or illegal behavior of a player on the court or on the team seat. Illegal contact with opposing players before the ball survives can also be judged as a technical foul. (1) Any player, coach or trainer who has no sportsmanship can be fined up to two technical fouls. Any violator who has no sportsmanship once can be dismissed; In both cases, immoral behavior must be expelled. Sportsless behavior, such as: it is impolite to talk to the referee; Physical contact referee; Express public dissatisfaction with the verdict; Use obscene language; The coach entered the venue without the permission of the referee; Stretch your elbow intentionally or try to tamper with it, but it doesn't involve contact. There are also some technical fouls that are not caused by immoral behavior, such as: delaying the game; Violation of the team seating area; When the ball becomes a dynamic ball, the number of people on the field is not enough or more than 5; The attacker deliberately hangs on the basket or backboard and so on. Touching the ball illegally during the dead ball, if it is considered immoral, can be sentenced to technical foul; If the contact is unnecessary and excessive, it can be judged as a malicious foul. (2) In a foul fight or a dead ball, the player, coach or trainer should record the technical foul and not punish the ball. Those who take part in the fight should be fired immediately. In addition, according to the situation, the fighter will be fined not more than $20,000 and suspended. In NBA games, the penalty for foul is more severe. An athlete, coach or trainer can be dismissed under the following circumstances: the elbow foul is at or below the contact shoulder level; Technical foul without sports moral behavior; A malicious foul caused by unnecessary or excessive contact. Athletes, coaches or trainers must be dismissed if they commit the following acts: boxing foul; Foul in a fight; Elbow foul is higher than the level of contact shoulder; Trying to punch without contact; Not the continuation of the game, but deliberately entering the stands. In order to punish and stop fouls, there are also provisions on fines in NBA rules. For example, if the referee thinks that the player is hanging from the basket on purpose, he should be sentenced to a technical foul and fined 100 USD; The first technical foul was fined 100 USD for immoral behavior, the second technical foul was fined 150 USD, and so on.

2. personal foul

After the ball survives, it is a personal foul to have illegal physical contact with the opposing team. Players are not allowed to pull, push or bump other players; Nor are you allowed to stretch your arms, legs, knees or bend your body into an abnormal posture to hinder the progress of the opposing team members. Violation of the regulations will be judged as a personal foul and will be punished according to relevant penalties.

(1) foul by both sides

Foul on both sides refers to the situation that two players who are not on the same team commit personal or technical fouls on each other almost at the same time.

Fines:

No matter personal or technical fouls, no penalty will be awarded, only the fouls of the players will be registered, not the fouls of the whole team. If a team owns the ball when both sides are convicted of a foul or a fight foul, it should keep the ball and throw a foul ball on the sideline near the place where the game was interrupted to continue the game. If neither side owns the ball when the foul is declared, or the ball is in the air when the shot is missed, any two players from different teams should jump the ball in the middle circle to continue the game. If the shot is successful and the score is valid, throw the foul ball at the baseline to continue the game. If the foul of both sides is the result of different opinions of the referees, no points will be scored, and any two players from different teams will jump the ball in the middle circle to continue the game.

(2) Offensive foul

After the ball survives, the attacking player makes illegal contact with the opponent, which is an offensive foul.

Personal foul of the attacker, if not elbow foul, boxing foul, or malicious foul, should be dealt with as follows: the attacker does not score; Register a foul player and commit a personal foul; Do not register the team's in-team foul (except for the sixth personal foul of the team and the team has no qualified substitute).

(3) foul without ball right

After the ball becomes a dynamic ball, it is a no-ball foul to make illegal contact with the opposing team without the ball rights of both sides.

If a player commits a personal foul, if it is not a boxing foul, a malicious foul or an elbow foul, and neither side owns the ball at the time of the foul, it will be punished as follows: (1) register the fouled player as a personal foul; Register a foul team for team foul; If the team's foul penalty does not appear, the opposing team is sentenced to throw a foul ball on the sideline near the foul place; If there is a team foul penalty, the infringed player will be awarded a penalty plus points.

If the defender is convicted of a foul without possession of the ball, and then the shot (free throw) is successful, the fouled side should be fined, making it possible for him to score 3 or 4 points. This rule applies to: no matter which offensive player fouls; Regardless of whether the team fouls or not.

If the attacker is convicted of a foul without possession of the ball, and then the attacker succeeds in shooting, no points will be scored.

(4) Boxing foul

It is a boxing foul for an athlete to slam his opponent.

It is a personal foul and a team foul for a player to be convicted of illegal contact because of boxing. Penalty should be awarded, regardless of whether the penalty is successful or not, the ball should be awarded to the infringed team to throw a foul ball in midfield.

Any player who punches his opponent, whether he hits or not, is immoral. He should be fired immediately and stop at least one game.

This rule applies to the game in progress and the dead ball state.

If boxing fouls occur one after another, all the contents of this rule will be applied, and the team that was finally fouled will throw a foul ball in the midfield.

In addition, according to the situation, the player was fined not more than $20,000 and was suspended.

(5) Non-competition foul

In the last two minutes of the fourth quarter or overtime, the defender made illegal contact with the attacker with the ball, and this contact occurred in the area far away from the ball or when the foul ball did not leave, which was a non-match foul penalty: registered individual foul and team foul; A free throw (elbow foul or malicious foul twice) can be executed by any player on the field; And the infringing team threw a foul ball near the place where the game was interrupted to continue the game.

(6) Team foul

Each team fouls more than 4 times in each game, and each team fouls more than 3 times in overtime, and the penalty points are added.

If the team fouls less than 4 times within 10 minute before each festival, or less than 3 times within 3 minutes before overtime, the team is allowed to make a team foul in the last two minutes without additional punishment.

If the player who is shooting has a personal foul, he will be sentenced to two free throws, and if there is a team foul penalty, he will not be sentenced to additional free throws; If the shooting is successful, a penalty will be awarded, and if there is a team foul penalty, no additional penalty will be awarded. In other words, a successful two-point shooting can get up to 3 points, and a successful three-point shooting can get up to 4 points.
