What exactly is the NBA draft? Can anyone tell me in detail?

Many procedures and rules of the NBA draft are still like smoke and mirrors to some Chinese fans today. Divided by time, the annual NBA draft can be roughly divided into two parts. The first part is the draft lottery: The NBA has implemented draft lottery since 1985. Every year when the playoffs are in full swing, the NBA will convene the teams that failed to enter the playoffs to hold a lottery ceremony to determine the top three rookie picks in the future. Belong. During the lottery ceremony, the host will take out 14 table tennis balls numbered 1-14, put them in a container, and randomly draw 4 balls from the 14 balls, regardless of the order of the numbers, one *** can produce There are 1001 possible combinations, and excluding this 11-12-13-14 combination, there are exactly 1000 remaining. Before the draw, teams that have not qualified for the playoffs have been ranked in reverse order according to their regular season records, and the corresponding number of combinations (probabilities) of winning the No. 1 pick have been obtained. For example, in the 2004-05 season, 14 teams did not enter the playoffs. Among these 14 teams, the Hawks with the worst record were given 250 combinations, which means they have a 25% chance of winning the No. 1 pick. The Hornets with the second worst record The team got 199 combinations, or a 19.9% ??chance. Based on this, the Timberwolves, with the best record among the 14 teams, only have 5 combinations, or a 0.5% chance of winning the No. 1 pick. After the No. 1 pick was drawn, the four ping-pong balls were put back into the container to re-determine the ownership of the No. 2 and No. 3 picks. After that, the remaining picks No. 4-30 in the first round and the second-round picks were , will be determined in reverse order according to the results of the regular season. In addition to the regular draft procedures, the NBA has also added some special regulations for American high school graduates and overseas players to participate in the draft. The following are the provisions of the NBA Collective Bargaining Agreement for these two types of players to participate in the NBA draft. Regulations for U.S. high school graduates applying to participate in the draft (a) A player who has settled in the United States and has completed high school studies may send a written notice to the NBA 45 days before the start of the draft, after expressing his intention to give up entering college to continue his studies. Be eligible to participate in the NBA draft. Once the player is selected by any NBA team, the following rules will apply: (i) Subject to (b) below, if the player does not play college basketball, he will be eligible to participate in the NBA Draft. If an NBA team issues an invitation to the player as required every year between the date he renounces his college chances and the date he becomes eligible to participate in the draft, that team will be the only team that can sign a player contract with him. . In this part, once the player does not declare his eligibility to participate in the college basketball team after becoming eligible for the NBA draft, then the draft will be regarded as a "second selection" for him. Players selected as a "second pick" will be subject to applicable rules. If the player who was selected in the draft because he forfeited his college basketball eligibility, did not sign a player contract with the team that selected him, and was not selected in the "secondary selection" (as explained in the previous statement) ), we call them rookie free agents. (ii) If the player participates in a college basketball team, he will still be eligible for the NBA draft if he later renounces the opportunity to continue playing in the college basketball team. At that time, the NBA team that selected him in the draft and issued invitations to the player as required every year will retain the priority to negotiate with him and sign a player contract one year after the date of the draft. In this part, once the player does not declare to give up his eligibility to participate in the college basketball team after being eligible for the NBA draft, then this draft will be regarded as a "primary" for him, and the next draft will be considered Writing is the "second choice". Players selected as a "second pick" will be subject to applicable rules. (b) A player who has settled in the United States and has completed high school education but is not eligible to participate in the NBA Draft and signs with a professional basketball team outside the United States will be eligible to participate in the next NBA Draft. If selected, he will be deemed a "player" as defined in Section 4 above. For the purposes of this section, "professional basketball team" means a basketball team in any country that pays a basketball player for it any type of money or compensation that exceeds ordinary living expenses. Rules for Overseas Players Participating in the NBA Draft (a) For the purposes of this section, an "overseas player" means any amateur or professional basketball player who resides outside the United States.

(b) An overseas player becomes eligible for the NBA draft upon reaching the age of 22. Any player over the age of 22 who has not been selected in the draft on his 22nd birthday is called a rookie free agent. (c) Notwithstanding the provisions of subsection (b) above, an overseas player who has not played college basketball in the United States may become eligible for the draft before his or her 22nd birthday: (i) He must be drafted during the draft He must have previously been at least 18 years old; (ii) He must give written notice to the NBA 45 days before the start of the draft expressing his desire to be eligible to participate in the draft. (d) An overseas player who plays for a U.S. college basketball team in the season prior to the draft must comply with the provisions of Section 5 above regarding continuing to complete or abandon college studies. As usual, the rules of the NBA draft lottery ceremony are as follows: put 14 ping pong balls marked with numbers 1 to 14 into a drum-shaped barrel, and pick any 4 balls from them to form a combination result, one** *There will be 1001 combination results. If one of the results is ignored, the remaining 1,000 results will be randomly assigned by the computer to 13 teams. The worse the team's regular season record, the more results will be allocated. The bottom team in the league will receive 225 results. Then four balls are shaken out like a lottery, and a set of four numbers is generated. Whichever team's results include this one will have the number one pick. Then the four balls are put back into the bucket, and the above process is repeated twice. The second and third picks are awarded (note: if the ignored result is shaken, it is invalid, the ball is put back and Repeat procedure). Teams that do not receive the top three picks will receive the fourth to 13th picks based on their regular season record. The worse the record, the higher the draft pick. According to regulations, the entire lottery process will be attended by NBA officials, representatives of the 13 teams, and accountants who supervise the lottery. After the "lottery" is over, the accountant will put the cards with each team's logo into three envelopes marked 1 to 3 and then seal them. Neither NBA Vice President Granick nor team representatives can know in advance what the outcome of the envelope will be at this time. The NBA will then officially announce the results of the lottery. The 4th to 13th picks will be announced in order from low to high. Then Granik will open the envelope and announce the teams with the top three picks in order. This means that the team named in the last opened envelope will win the "number one pick" in the draft one month later. Edit this paragraph NBA Draft Lottery The NBA Executive Committee met in Salt Lake City in June 1984, when they voted to determine the order in which teams that missed the playoffs would select first-round picks. This system started in 1985. Before that, from 1966 to 1984, the team with the worst record in the East and West would flip a coin to determine who would get the right to draft first. In the NBA draft lottery, the team with the worst regular season record is most likely to receive the first pick, while the team with the best record that missed the playoffs has the least chance. The lottery will determine the selection order of the first three teams, while the remaining teams that have not qualified for the playoffs will be selected in reverse order of their regular season records. During the lottery ceremony, the host will place 14 table tennis balls numbered 1-14 in a drum-shaped container. Randomly drawing 4 balls from 14 balls can produce 1001 possible combinations, regardless of the order of selection. Before the draw, teams participating in the draw were given 1,000 combinations based on their regular season rankings. 4 ping pong balls will be drawn to the top of the container in order to form a four-digit combination, and the team that obtains this combination will receive the top pick. Then, the four ping pong balls will be returned to the bottom of the container, and the previous situation will be repeated to determine who owns the second and third picks. If the drawn combination is not within the allocated range, the draw will be repeated. Edit this paragraph to select players. All American players can automatically enter the NBA draft after they graduate from college. American players can also declare for the draft between the time they graduate from high school and the time they complete college. The NBA sets two dates for players to declare for the draft. All players who wish to participate in the draft are not automatically eligible for the draft. They must declare for the draft before or on the first day to declare for the draft.

After that, the NBA will set up several pre-draft training camps for players who may participate in the draft in the future, allowing players to demonstrate their abilities and skills to league teams in the training camps. Any player can decide to withdraw his or her name before the final day of declaring for the draft and decide not to participate in that year's draft. The final day of declaring for the draft is one week before the draft. This is important for current college players because they will not lose their college eligibility if they declare for the draft on or before the first declaration day, as opposed to if they do not officially declare for the draft until the final declaration day. If they are drafted, no matter whether an NBA team eventually selects them, they will lose the opportunity to further study in college. Another point is that if a player signs with an agent, he will automatically end his college studies. When a player is selected in the first round, the team that selects him must sign a contract with him for at least four (3+1 or 2+2) years, while players selected in the second round must sign a contract with him for at least four (3+1 or 2+2) years. The player's team can "own" the player for three years, but the team does not have to sign with them. The earlier a player is selected in the draft, the higher his value. The first player selected in the draft is usually called the "number one pick", and they are usually the best players among all the players participating in the draft. However, just because a player is selected with the first pick in the first round does not mean that the player will definitely become a superstar in the future. Michael Jordan was selected with the third overall pick in the 1984 NBA Draft, but he is widely regarded as the greatest player in NBA history. One of the two players selected before Jordan was "Big Dream" Olajuwon, and the other was Sam Bowie. Olajuwon was elected to the NBA Hall of Fame after experiencing a great career. , and Sam Bowie ended his career hastily due to constant injury problems and did not achieve anything at all. All of this shows that there is no inevitable direct connection between NBA draft results and the future development of players. Players selected later in the draft are not necessarily worse than players selected earlier. Edit this paragraph After selecting the rookie, the team can choose to sign with him, give up or directly exchange him. If the rookie is given up, he will become a free agent (non-restricted). If it is a trade, he has not been acquired. Rookie contracts, like draft picks, have zero salary value. After a team signs a rookie, it cannot trade him within 60 days. If a rookie is unwilling to sign with the team that selected him, and the team does not agree to trade or waive him, the rookie will not be able to sign with other NBA teams within one year, and the team that selected him retains the right to sign for one year; The rookie can also participate in next year's draft.
