NBA:
The NBA’s season was canceled partway through in March. The league did not want to the season be all for naught. Their solution was creating the NBA Bubble. It invited the 22 teams that were within six games of a playoff spot to play eight additional season games to determine the playoff seeding. The NBA playoffs began with 7-game series as expected Aug. 17. The NBA Finals begin Sept. 30. Notably, several games during the bubble were halted due to BLM protests started by the players. The bubble has served as both a way to resume basketball but also a way to create unity amongst the players.
