When two fighters, who are almost evenly matched, fight multiple times, the outcome of each bout eventually becomes subject to the law of probabilities. In other words, the more times the combatants fight, the greater each one’s chance of losing – or winning.
Applying this same law to Manny Pacquiao and Juan Manuel Marquez, if they fought 10 times, they would probably win five fights each, on average, minus of course the controversial decisions from the judges. Now, after four fights, the question is, when is enough enough? After such a sensational ending to the fourth fight, an unbiased person would assume that the story has finally ended. Game over. Marquez finally silenced his critics.
