The second round (3 1 ~ 60) is arranged in the reverse order of the team's regular season performance.
In the signing stage, the rookie can choose to sign with him, or give up, or exchange directly after being selected by the team. Assuming that the rookie is abandoned, he will become a free agent (unrestricted). If the rookie doesn't want to sign with the team that selected him in turn and the team doesn't give him up at the same time, then the rookie can't sign with other nba teams within one year, and the team that selected him has the right to sign for one year. Rookie can participate in next year's draft.
