Still think NBA can have games in May if they use a cordoned off centralized location, with only team, coaches, doctors, and a skeleton crew of media. By then point-of-care tests are likely available. The key is testing prior to arrival, before entrance into the hermetically sealed basketball bunker.
Maybe itll be college tournament style. Every game on the same court. Make it a one-and-done, best out of three. Get creative, whatever. Just do it.
