Great athletes have the potential to change the game they play...and change the world we live in. From Muhammad Ali and Arthur Ashe to Billie Jean King and Colin Kaepernick, sports heroes throughout history have used their platforms to effect social change and speak out about injustice. Tennis star James Blake has written about this history and how he has been inspired by athletes willing to raise a fist, take a stand or take a knee. His new book is called "Ways of Grace: Stories of Activism, Adversity, and How Sports Can Bring Us Together" and he joins 1A guest host Noel King to discuss athletes and activism.
