Football, 1975: Dave Kopay was pissed. It was December 1975 and he had read an article in the Washington Star newspaper that dealt with the difficulties of being a homosexual in sports. It quoted, without naming him, an NFL player and his experiences. Kopay knew at once that the player was his former Washington Redskins teammate Jerry Smith, with whom he had had a sexual encounter.
