Now obviously Mayweather and Pacquiao are on different levels in comparison to their opposition as of late. But also note their opponents have been coming into the ring with quite sizeable weight advantages. You know the old boxing addage: Speed kills. How much of their recent victories have been attributable to their opponent's "weight advantage", considering that many of their opponents have been rehydrating to up to a weight that is a class or two well above WW, and carrying too much water weight thus slowing them down?
