Although age eventually robs every fighter of his speed, Pacquiao still maintains one of his greatest virtues. Up to the moment he suffered that fateful knockout last December, Pacquiao had bested Juan Manuel Marquez with his hand speed, quick feet and dizzying combinations. Rios, for his part, might have added power after putting on muscle and weight, but it's possible (likely?) that he traded away some speed for those gains.
