Now that the NBA has finalized its plan for the summer restart and teams have reported to Orlando, we have a pretty clear idea of what the rest of the 2019/20 season will look like, assuming it can be completed. However, uncertainty looms over the ’20/21 campaign, which doesn’t yet have an official start date.

According to Alex Silverman of Morning Consult, the NBA’s Global Innovation Group recently sent out an internal planning document outlining four possible scenarios for the 2020/21 season. Three of the proposed scenarios would feature a December start date and a July end date, but the fourth would see the season start in March 2021 and run through October, Silverman writes.

As Silverman explains, that fourth scenario is one that could be considered if there’s a pathway in early 2021 to a coronavirus vaccine or therapeutic treatment for COVID-19 that would allow teams to host fans in their home arenas for a full season. Under that proposal, the league would consider breaking for the Tokyo Olympics in the summer and would execute a “rolling schedule” rather than releasing the full-season schedule at once, Silverman writes.
