Who would be your pick ? Mine include - Muhammad Ali Roberto Duran Sugar Ray Robinson Max Baer Archie Moore Jack Johnson Loads more will no doubt come to mind later.
I couldn't agree more with your list Stevie G..except maybe to include Jack Demsey, who was a symbolic figure along with Babe Ruth of the Roaring 20's.
If Duran could speak English he'd be as big as Ali. What a character. Tito Trinidad was also very charismatic.
