Colin Kaepernick’s 49ers jersey has become the N-F-L’s top seller, and not just among people who want to make videos setting one on fire. The former Nevada star Q-B says he’ll pay the profit forward.  Kaepernick says he’ll give all the profits from his jersey sales to charity. Kaepernick is getting support for his refusal to stand for the National Anthem from other NFL players, who agree that the apparent differences in the way police treat minorities need to be addressed in more thoughtful ways.
