The Kaepernick Effect: a story of the other athletes who kneeled in protest

In his new book, Dave Zirin explores the ripple effect of the NFL quarterback's protests, and how he inspired activists at all levels of American sports

Colin Kaepernick no longer waits for the call to rejoin the NFL. Five years have passed since Kaepernick first sat, then took a knee, during the national anthem to protest police brutality and racial injustice in America. Four years have passed since Kaepernick was ousted from the NFL for his peaceful demonstration. He has never been invited back, despite remaining in top playing shape and possessing the talent to be on a roster.

Kaepernick's work in the aftermath of his protest transcended football, and he is still as busy as ever. He has written books: one on on criminal justice, and another for children. And he has partnered with acclaimed filmmaker Ava DuVernay to create a Netflix docuseries that debuts on 29 October with a focus on his teenage years and the upbringing that framed his social conscience. While Kaepernick is no longer part of the daily news cycle, his legacy has evolved, a legacy captured in the new book, The Kaepernick Effect: Taking a Knee, Changing the World by Dave Zirin, one of America's preeminent voices on the intersection of sports and politics.
