I doubt that will happen. Playing or singing the anthem at sporting events - from high school through professional - is a tradition ingrained in the fabric of American society.

Not playing/singing the anthem would itself be politicized. Some would applaud that decision. Others would be outraged and would condemn it. In short, the controversy would not only still exist but it could become even more of an issue with even greater emotional input/output on both sides than there is now.
