The NBA draft is an annual activity to select new players for the NBA. In the draft, 30 NBA teams can choose young male players who want to join the NBA. The selected players are called NBA rookies.
All American players can automatically enter the NBA draft after graduating from college, or they can announce their participation in the draft between high school graduation and college completion.
Team selection in nba draft
When a player is selected in the first draft, the team that selected him must sign with him for at least four years (3+ 1 or 2+2), while the team that selected the player in the second round can "own" the player for three years, but the team does not have to sign with them.
If a player signs a contract with his agent, he will automatically end his college studies. If the rookie is abandoned, he will become a free agent (unrestricted). After the team signed a contract with the rookie, they could not trade him for 60 days.
