So Mayweather took Corrales down eventually, and other guys, and people like Gatti would have been ko'ed by him, does that mean he can hit hard or that he is an accumalation with speed? I haven't seen Pacquaio beat a top fighter by a ko in a long time( and no the last two fights MOrrales was not a top fighter, at least not at 130). The last time I saw him take out a guy who I didn't expect him to was Barrera, and that was at 125. He didn't ko Marquez or Morrales in their first fights, and I don't think it was because Pacquaio has become so much better(he is a bit better), but that Morrales aged so obviously that he was able to dominated MOrrales the third fight, and in the second fight I had Morrales winning until he ran out of gas.
