The NBA quietly changed trade rules over the offseason to allow teams to simultaneously owe two picks with a "two years after" language attached.

In the past, a team could owe only one such pick.

The Los Angeles Clippers, for example, can trade a 2021 or 2022 first round pick despite owing a lottery protected pick to the Raptors and a first round pick that goes to the Celtics "two years after" the pick to Toronto is conveyed.

Due to the Stepien rule, teams cannot trade first round picks in consecutive years.
