What is the NBA draft? Why don't some teams have draft picks?

Draft right means that NBA teams have the right to choose new talents in the draft at the end of the season. Each team automatically has a first-round draft pick and a second-round draft pick every year. First-round draft selection right means that NBA teams have the right to select new players in the first round according to the pre-arranged order in the draft. The most important things in the first round of draft are the number one pick, the number two pick and the number one pick. They are the first, second and third draft picks in the first round. Players selected by the top draft are called "top show", while players selected by the second prize and flower-exploring draft are called "second prize show" and "flower-exploring show". The top three draft picks (namely "No.1 scholar", "No.1 scholar" and "No.1 scholar") must be decided by drawing lots. The teams eligible to participate in the lottery are 14 teams that were not eligible for the playoffs that year. Usually, when the playoffs are in full swing, the league will call 14 teams to draw lots for draft picks. After the first prize is drawn, the ownership of the second prize and the flower exploration prize is also drawn. However, teams that sign any of the top three draft picks are not allowed to participate in the next round of lottery.
