I absolutely hate the emphasis on being undefeated in boxing. Like, I saw Castillo, Oscar, Maidana, and Pacquiao beat Mayweather, but I'm forced to accept that he's undefeated on paper because the 0 is still there. Mayweather should be 45-4.
Another example is Danny Garcia. We done saw his ass get tapped by Mauricio and PEDerson, but he's officially undefeated.
