Marking 15 years Sunday, the September 11th attacks were a national tragedy. As the passenger planes struck the towers and Pentagon, all of America froze in terror and agony. For much of Sunday, the entirety of the United States was in mourning for the 3000 lives lost in the attack. During the 13 NFL games, there were many tributes paid to victims as well as first responders on the site. There were cleats and tweets of note from players. But in addition to acknowledging 9/11, at the same time, the NFL has been in the midst of a national controversy regarding the national anthem. San Francisco 49ers quarterback Colin Kaepernick has sat or knelt during the reciting of the Star Spangled Banner during every game of this preseason. Players have begun to join him, and Sunday was no different. Dolphin’s running back, Arian Foster (along with 3 teammates), joined in on the protests by kneeling against racial discrimination. Martellus Bennett, Devin McCourty, and Marcus Peters raised their fists while standing. The Kansas City Chiefs and Seattle Seahawks both stood with their arms interlocked in a show of unity. What will become of this?
