Though I think a lot of old school phrasing says if your undefeated it just means you havent tested yourself or fought the absolute best there is out there thats not necessarily the case either but for lots of undefeated guys there is some truth
Name a fight apart from Castillo where floyd actually tested his abilities De la Hoya was washed up and that was close but floyd won, and stunk the place out Floyd didnt make the Williams or pacquiao fights where high volume punchers would have really tested his defensive abilities He's a coward for not testing himself
