The use of bill of exchange right in transaction

Teams can also use the transaction to exchange other teams' draft picks, or exchange their own draft picks in the transaction. However, when the draft option is used for trading, it can only be given away for nothing and cannot be converted into salary for trading calculation. In addition, some draft options are protected. According to the relevant regulations of NBA, the team shall not send out the first round draft pick for the next two years in a row during the transaction. For example, in the 99-00 season, teams can send away the first-round draft pick in 2000, regardless of whether they have the first-round draft pick in 1999, because the draft pick in 1999 is no longer a "future" draft pick. But they can't exchange first-round draft picks at 00 and 0 1. There is also a protected situation, that is, the sender and receiver of the bill of exchange rights negotiate terms when trading the bill of exchange rights. If the top three draft rights are drawn in the lottery, they still belong to the sender, and the receiver has no right to use the draft rights. In these two protected cases, the option can only be used by the original owner.
