I haven't seen this brought up in here before, but with all of this "Mayweathers toughest fight" business, I was wondering who you all thought had the greatest round against Mayweather in his 46 pro fights. No stupid amateur or sparring matches(Paul Spadafora) allowed. Only his pro fights. Right off the top of my head Im thinking Sugar Shane Round 2 of their fight. Ill probably switch my answer but off the top, i think he buckled Floyd a couple times like no one has ever done before or since.
