I speak to a lot
of younger guys who think Mayweather is the greatest fighter ever.
Him, along with Roy Jones and a few others they know of like Ray Leonard and Ray Robinson.
It boils down to just being ignorant. They don't know about the past and aren't prepared to learn. Pretty stupid IMO
But the majority of people who consider Mayweather to be the greatest fighter of all time, base it off his skills. That, along with the fact he's the first or one of the first ATG's they have witnessed.
