He beat Marquez twice? He beat Morales 3 times?
He barely beat Marquez once, he lost once to Morales. You can't be listing fighters losses like that to impress people. That's now how you measure accomplishments or how good a resume is.
And I would put Pacquiao as the 4th best fighter of 2000-2009.
Mayweather, Hopkins, Marquez ranking before Pacquiao.
