Gregg Popovich has been outspoken over the years in his advocacy for racial justice and equality in America, but the Spurs coach was reticent Friday night about why he stood for the national anthem rather than take a knee with members of his team and the Kings.

"I'd prefer to keep that to myself," he told reporters after San Antonio's 129-120 victory over Sacramento. "Everybody has to make a personal decision."

Popovich said that the NBA has been "great" about allowing people to decide whether to stand or to kneel as a show of protest against police brutality and racial injustice.
