No margo was never that great to begin with, but people wanted to believe at that time that a man existed at WW who could defeat floyd. They chose Margo having watched the video of margarito asking floyd to fight. From there the perception of the ducker was created. They tried to do the same thing with cotto, but we know how that turned out. The only one left now is Pac, and if that don't work I don't know who people will ride next as the man to beat floyd at WW.
