For sure, Pacquiao was to and that's why they are/were so easy to label that way.

The trouble is that ability and achievements actually have nothing to do with each other, there is no common denominator between them. When you combine the two in ranking fighters it is inherently just speculation, then add the fact that men fight differently to suit their natural size/frame and it's left without merit. Is Wladimir Klitschko better than Juan Estrada, or Rigondeaux? It's a ridiculous thing to ask.
