Here's a great podcast about some of the best boxers of all time (according to the Kyle McLachlan of course). McLachlan has it as... 10: Barney Ross 9: Bob Fitzsimmons 8: Willy Pep 7: Muhammad Ali 6: Ezzard Charles 5: Roberto Duran 4: Sam Langford 3: Sugar Ray Robinson 2: Henry Armstrong 1: Harry Greb It's a great listen (although has some fruity language so not for kids). I had wikipedia open as I listened just to look up some of the names mentioned (there's lots of background on who this top 10 fought). An absolute gem for boxing history and context.
