How will this impact the regular-season schedule and standings?
Typically, the NBA sends out a full 82-game schedule in mid-August. This year, though, the league only sent 80 games, with a gap in the schedule from Dec. 3-10. Each team's final two regular-season games will be determined by how the in-season tournament plays out.
The 22 teams that fail to qualify for the knockout rounds of the in-season tournament will have their final two games scheduled -- one at home and one on the road -- on Dec. 6 and 8 against other teams eliminated in the group stage.
The East teams that lose in the quarterfinals and the West teams that lose in the quarterfinals will play each other on Dec. 7. The teams that lose in the semifinals in Las Vegas will have played their full allotment of 82 games, while the teams that reach the championship game will actually wind up playing 83 games -- with the championship game not counting toward the regular-season standings.
