I think people don't recognize the dominance of Floyd mayweather. Because he is so passive in how he fights. His speed is flashy but he doesn't avoid punches in fan friendly styles like whitaker or Roy jones. Also he is amazing in how economic he is offensively, but people don't appreciate it. Statistically he dominated Oscar and hatton but they looked like they were competitive because Floyd doesn't dominate guys physically like mosley or Roy jones did. Nor does he have the power to overwhelm guys ala pacquiao. If you look at fights with a technical mentality he is just as dominant as Roy or Pernell.
