There remains a lot to be done before the 2020-21 NBA season can get started, but probably the most important aspect that must get sorted out is the salary cap situation. Simply put, there is no way to have an offseason without establishing the salary cap.
It has long been expected that the salary cap would decline as it is based on league revenues. Due to the ongoing coronavirus (COVID-19) pandemic, the NBA suffered a major loss in revenue which will now have a huge impact on the cap and team strategy during the offseason.
If it is lower, teams will have to be very selective in how they use their cap space to bring in or re-sign players.
