The entire NBA community is hoping that the 2019-2020 season will eventually continue soon. A potential return is currently being discussed, and the NBA has sent out a survey to general managers on the fate of this season.
The NBA General Managers were given the following options to vote from: (per Shams Charnia)
1. 16 teams directly to the playoffs
2. “Playoff Plus” (play-in or group stage)
3. All 3 NBA teams with play-in tournament
It seems that there is no consideration to finish the regular season. Some sort of tournament will take place to crown a champion. Either the traditional playoff tournament will take place or a tournament with all 30 teams.
