If you only know the Ali-Frazier fights as abstractions, go watch the first and the third. Even stripped of greater cultural context, they're remarkable athletic demonstrations. This might not be true for people who can't get past the brutality, but for me, a great fight carries an energy unmatched by any other happening in sports. Actually, that's true because of the brutality, the sense that something more elemental than victory is at stake. If any sporting event has captured that feeling more potently than the Thrilla in Manila, I haven't seen it.
