Lots of those "bums" have impressive records. Chalky Wright is in the HOF.

Only flomos and casuals are dazzled by the 0. What makes 49-0 more impressive than 151-21? If someone has 3x the amount of fights it's more likely they will lose.

It's impossible to compare fighters from history because things are so different. Floyd may well have gone 151-21 back then just like Armstrong might be 49-0 today. They're both great fighters of their time and neither beat a load of "bums."
