Welterweight history ? obviously the first candidate is Sugar Ray Robinson but i heard he got dropped alot especially in his early career but he was only stopped once in his career at a much heigher weightclass due to the heat so you can't argue with that.................

Then we have other tough guys of the older era like Carmen Basilio/Kid Gavilan/Barney Ross.................

But then we have some of the newer generation like Shane Mosley/Pernell Whitaker/Oscar De La Hoya............

But anyway where does Antonio Margarito's chin rate in Welterweight history ? i would say he is close to the top 5 if not in the top 5.
