"All of those guys beat each other but nobody beat Floyd Mayweather" -PBF

Some facts:
Cotto beat Mosley for the True Welterweight title
Margarito beat Cotto for the True Welterweight title
Mosley beat Margarito for the True Welterweight title

Somewhere during all of this Floyd Mayweather beats Light Welterweight champion Ricky Hatton for a Vacant Welterweight Title

Floyd is correct, none of those guys did beat him. LEGEND
