For real though, how many times does Manny have to beat guys bigger than him?

People said Oscar at 154 would be way too big for Mayweather regardless of his defensive skill, and the first punch landed would cause him to crumple in the wind. I am sorry, but 20 pounds doesn't make the same difference 80 pounds makes. I could see Mike Tyson or Tua crumpling Mayweather with one punch, but not Cotto.

As a heavyweight I fight guys who are 40 pounds heavier than me, and sometimes they have way less power than light heavyweights.
