(NFL Network) It’s been roughly six months since San Francisco 49ers quarterback Colin Kaepernick’s national anthem protest went public, and things haven’t been the same since. More NFL players decided to follow his lead in bringing attention to the issue of unarmed African-Americans dying at the hands of police. Athletes in other sports also joined in, while police officers, military veterans and ordinary citizens talked about the problem from their own perspectives. There was plenty of dialogue and debate, fury and frustration. But what became clear in all this is something even Kaepernick couldn’t have known: The world of sports was the perfect place to ignite a new conversation about race in our society.
