If so, this is going to be a BIG problem for a while. If not, the NBA will eventually resume around late May. Maybe early May. When the league does resume, they’ll have a month of regular-season games to catch up on. This means the playoffs wouldn’t start until late June, possibly even early July. Normally the time the NBA postseason ends.
Now, you’re talking about an NBA postseason that in theory spills into August, and potentially September. Just a month before the 2020-21 season is supposed to start…
Therefore, the NBA will likely shorten/cancel the regular season or the playoffs. This could mean canceling regular-season games that teams needed to a fighting chance to get in the playoffs. Or, this could mean eliminating the lower seeds from the playoffs.
