Competition format
The COVID-19 pandemic has resulted in some changes from the most recent pre-COVID format involving two stand alone conferences. For this season, each of the conferences will be further split into two divisions, Atlantic and Central in the Eastern Conference and Mountain and Pacific in the Western Conference, creating four geographically based divisions of 8 (or 7) teams. The teams will play a 32-game schedule in a 27-week period starting around May 1. Individual teams can start their seasons between April 24 and May 15, based on crowd restrictions due to the COVID-19 pandemic. During the regular season, each team will play its division opponents four times – twice home, twice away, for a total of 28 (or in the Mountain Division, 24) games, making up the bulk of each team's season. The remaining games in each teams schedule will be played against regional or cross-conference opponents.
