Mayweather cannot beat that record being an 8 division champion. Pacquiao will be the only person within this generation that has the audacity to get to that accomplishment. Mayweather might have an unbeaten record but he did not start from the bottom up. Yah, he can brag about it all he wants.
It is impossible to match the number of divisions Manny Pacquiao conquered throughout his career by majority of the fighters and he was an exceptional talent and i have read about his childhood struggle and we are yet to know the amount of fights he had as an amateur. Both these fighters are regarded as legends by many boxing fans
The only real question now though is, does Mayweather really want to fight Pacquiao? The other question is, would Pacquiao want to lose to Mayweather?
Mayweather might be trying to understand the market hype and he already tried to match up with others for exhibition fight but it attained luke warm response but a Manny rematch will be one of the biggest fights in history.
