“Nearly all the writers regarded Clay’s bombast, in prose and verse, as the ravings of a lunatic. But not only did Clay have a sense of how to fill a reporter’s notebook and, thus, a promoter’s arena, he had a sense of self. The truth (and it was a truth he shared with almost no one) was that Cassius Clay knew that for all his ability, for all his speed and cunning, he had never met a fighter like Sonny Liston.”

- David Remnick, King of the World
