If there was any doubt NBA Commissioner Adam Silver meant what he said about preferring that players stand for the national anthem, it went away Friday when the league sent out a memo reinforcing its rule that players and coaches must do so.

The memo, which ESPN reported was sent by deputy commissioner Mark Tatum, reinforces the rule that has been in place for decades: that players, coaches and trainers “should remain reasonably still, stand tall in a straight and orderly line, and act in a respectful manner through the period.”

The original intent of the rule was to make sure players weren’t shooting around or stretching while the anthem was being played before a game. In light of recent events – specifically comments made by President Donald Trump last week at a rally in Alabama regarding NFL players before uninviting the Golden State Warriors from a White House visit with a Saturday morning tweet – the rule has since come under greater scrutiny.

“We have a rule that requires our players to stand for the anthem,” Silver said Thursday at the conclusion of this week’s Board of Governors meetings in New York. “It’s been our rule for as long as I’ve been involved with the league, and my expectation is that our players will continue to stand for the anthem.”

The question now: Will players or coaches defy the league’s mandate? No one protested during the anthem last season after Colin Kaepernick started kneeling to protest police brutality and racial inequality. Dozens of players did before Sunday’s NFL games in the wake of Trump calling anyone who did so a “son of a bitch” and saying they should be fired.

The Warriors made known Friday that they have no plans to do anything at the opening game of the preseason in Oakland on Saturday against the Denver Nuggets.

“I haven’t been made aware of it. If there were to be something, I would’ve heard,” Warriors Coach Steve Kerr told reporters after practice Friday. “That’s what we talk about as a group. We never do anything without the whole team discussing it. At this point, there’s no plans.”
