For teams, letting players leave their markets felt inevitable. The NBPA had pushed hard for player movement during the hiatus, and the league never believed it could do anything but recommend players stay close to their respective organizations. Many players’ families live outside of the markets they play in, and the possibility of three months apart before restarting — or the possibility of a canceled season — was a non-starter. The NBA has set up testing and treatment protocols in cities where NBA players live, including one non-NBA city: Las Vegas, a league source said.
