Race and social justice took center stage during the NFL's opening weekend, when protests during the anthem, unifying T-shirts and decals honoring victims of police brutality were methods players and coaches used to make their voices heard.

Add on that an NFL-record 10 Black quarterbacks started Week 1.

Yet it was the Miami Dolphins, with coach Brian Flores' on-camera support, who made perhaps the most memorable statement before the games began. They released a video in which 18 players called out the NFL's "fluff" reaction and team owners' lack of action in impacting real change.

It was the conviction of the Dolphins' message, not their decision to stay in the locker room during the playing of the national anthem and "Lift Ev'ry Voice and Sing," that stood out.

NFL player activism came to the fore in 2016 when former San Francisco 49ers quarterback Colin Kaepernick first sat on the bench and then took a knee during the anthem in protest of racial injustice. Now in 2020, after the killings of Black men and women such as George Floyd and Breonna Taylor, there is a new wave of activism among athletes. It provides a backdrop to the continued call for the NFL and its teams to do more for diversity and inclusion.
