ESPN reported that the NBA is “closing in” on this second bubble, which NBPA executive director Michele Roberts said last week would have to meet the same safety protocols as the one created in Orlando for the 22-team restart. The most recent conversations have centered on a mini-training camp and subsequent games, which would be similar to summer league. According to sources, numerous details are still being determined, significant hurdles remain, an official decision hasn’t been made and the second bubble needs approval from the Players Association, which isn’t guaranteed.
