Ex-49ers quarterback Colin Kaepernick remains unsigned and is still an NFL free agent. Kaepernick, who once guided San Francisco to a Super Bowl, lost out on a Seahawks roster spot to Austin Davis. Many pundits have said Kaepernick remains a free agent due to the controversy surrounding his choice to not stand for the national anthem last season... ... and judging from the following retweets, it would seem he agrees. KnowYourRightsCamp is "a free campaign for youth funded by Kaepernick to raise awareness on self-empowerment & interacting with law enforcement," according to the profile's bio. The 29-year-old made waves last year for his national anthem protest, which he carried out due to police brutality against the African American community.
