Regional bubbles next season?

We’re a ways off from next season, but league sources have told me that the NBA is looking at options that include creating regional bubbles, should the COVID-19 pandemic still prevent normal business in the fall. Teams would report to a bubble for short stints—around a month—which would be followed by 1-2 weeks off. Ideally, the NBA would like to play an 82-game schedule that starts in December. A December start would allow the league to end the season in late June, putting the NBA back on a normal schedule and, importantly, not compete with the Olympics next summer. The players union is expected to take issue with that, preferring teams, particularly those making deep playoff runs, have more time off.
