Brees told Yahoo Finance on Wednesday he would never agree with the gesture.
“I will never agree with anybody disrespecting the flag of the United States of America or our country. Let me just tell you what I see or what I feel when the national anthem is played and when I look at the flag of the United States,” the 41-year-old quarterback told the outlet.
Brees likened standing for the national anthem as saluting the military.
“I envision my two grandfathers, who fought for this country during World War II, one in the Army and one in the Marine Corps. Both risking their lives to protect our country and to try to make our country and this world a better place. So every time I stand with my hand over my heart looking at that flag and singing the national anthem, that’s what I think about,” he said.
“And in many cases, that brings me to tears, thinking about all that has been sacrificed. Not just those in the military, but for that matter, those throughout the civil rights movements of the ‘60s, and all that has been endured by so many people up until this point. And is everything right with our country right now? No, it is not. We still have a long way to go. But I think what you do by standing there and showing respect to the flag with your hand over your heart, is it shows unity. It shows that we are all in this together, we can all do better and that we are all part of the solution.”
Brees’ teammate Michael Thomas appeared to react to the quarterback’s comments on Twitter.
Brees had previously made comments about standing during the national anthem during the 2017 season. At the time, he said he didn’t agree with President Trump’s comments about Colin Kaepernick or players who kneel during the anthem but still said players should stand.
“I will always feel that if you are an American the national anthem is an opportunity for us all to stand up together, to be unified and show respect for our country, and to show respect for what it stands for,” Brees said at the time.
He would also add: “But if the protest becomes that we are going to sit down or kneel and not show respect to the United States of America and everything that it symbolizes, and everything that it stands for, and everything our country has been through to get to this point, I don’t agree with that.”
While other players on his team protested in 2017, Brees said their reasons were “justified.”
“I will never say it’s OK to not show respect to the flag of the United States of America during the national anthem,” he said. “That is the symbol of showing respect to our country. I won’t. I don’t think that that’s OK because of all who have fought so hard and died and sacrificed so much for us to have the things we have, to have the freedoms that we have. The very freedom of the speech that we are talking about was born from that flag.”
Brees didn’t say what method of protest would have been acceptable.
