Boston will get a chance to rectify one of those early losses with a Friday trip to Philadelphia, in which the Celtics will take on the 76ers in the opening round of the NBA Cup. As in previous years, NBA Cup games will count toward teams’ regular-season records with four teams from each conference advancing to a knockout tournament.

All 30 NBA clubs will compete in the round-robin, group-format NBA Cup, which should not be confused with the NBA Playoffs or NBA Finals.
