I just want to know, how did the Nets send away the draft picks in a row?

Specific: 20 16:

First round signing: sent to Celtic without protection.

Second round signing: The Clippers have the right to exchange draft picks with the Nets unless they rank in the top five in this season's regular season.

20 17

First round signing: The Celtics have the right to exchange the first round signing with the Nets. If the Green Shirts decide to swap, they will send this year's second round to the Nets as long as their record ranks at the bottom of the league with 15.

The second round of signing: sending eagles.

20 18

First round signing: sent to Celtic without protection.

Round Two: They got a knight's second round before, plus the second round they already have. The top ranking belongs to the 76 ers, and the bottom ranking belongs to the Hornets. Well, the Nets don't have any.
