When you are talking about fighters of this level, size does matter. Leonard was a huge welterweight as was Hearns. Mayweather is weighing 150 pounds three weeks from the fight. He is much smaller than Leonard or Hearns. I would like Mayweather's chances against most fighters in history at 135 but there are several atg welterweights that would probably beat him. I think Mayweather and Duran at 135 would be a great fight. I know Duran won the first fight against Leonard at 147 but Duran matched up better against Leonard than Mayweather does. You saw what happened to Duran when he fought Hearns at 154.
I think you misinterpreted me. I meant imagine the situation if it was Hearns that landed that bomb on Floyd instead of Shane. :deal
