We need way more fights first. Mayweather obviously #1 2. =? Pac? - Lost to Marquez, Beat Bradley.. how good are they lately? how good is he? declining steadily since 2010 3. =? Bradley? - Lost to Pac, Beat Marquez, Looked so-so vs Abregu and Provodnikov at 147. 4. =? Marquez? - Beat Pac, Lost to Bradley, Looked ok vs Alvarado but too slow for some technical match ups, can't give him 4th head to head 5. =? Brook? - Beat Porter, Beat a few fringe guys, needs more big wins 6. =? Thurman? - No big wins 7. =? Khan? - Beat Collazo, fragile chin means he will always be hot and cold 8. =? Porter? - Beat Alexander, Beat Malignaggi, Lost to Brook 9. =? Alexander? - Beat Matthysse, Beat Maidana, Lost to Porter, Bradley.. the nearly man. 10. =? Maidana? - Beat Broner, Lost to Alexander, Lost to Mayweather etc We need way more match ups before having a clue. I think head to head it will be something like this come the end of 2015. 1. Mayweather 2. Brook 3. Spence 4. Pacquiao 5. Thurman
the whole things a ***** not half enough of the top guys fight each other mayweather being top is even debatable
