In proposals that include adoption of in-season tournaments and post-season play-in, the traditional regular season schedule would be reduced from 82 games — with most teams scheduled to play 78 or 79 games. There’s an extremely limited possibility of a team playing a maximum of 83 games based on on possible tournament and play-in scenarios, league sources said. For the in-season tournament, the NBA is focused on 30-team participation that begins with a divisional group stage of scheduled regular-season games. Those pre-knockout round games will be part of the regular-season schedule. Six divisional winners — based on home and away records in the group stage — and teams with the next two best records would advance to a single-elimination knockout round, league sources said. Those teams could each potentially compete in the quarterfinals, semifinals and finals.
