Pacquiao, Oscar and Canelo, even if they weren't in their prime, are still better wins then Jersey Joe, especially since he should have lost to Joe in the first fight.
Walcott's record is patchy for various reasons. As a general rule, because fighters fought so often back then, losses were more understandable than a straight knock on their quality. It's about when you beat guys. Louis beat Walcott - a renowned classy operator - at his best. Would go onto give Marciano - in The Rock's own words - his hardest fight.
Yeah I think it was you on another discussion about the layoff's of both Ali and Louis saying you see Louis defending 20-25 more times.
I asked that question a few weeks ago. Most people thought he would have had more but not everyone said how much more. I would suppose
Mayweather avoided too many fighters and aged other fighters out as well as having a personal contract with the USADA,for all the fighters Mayweather did beat he was never an Undisputed Champion in any Division . https://www.sbnation.com/longform/2015/9/9/9271811/can-boxing-trust-usada
No one it just wasn't the strongest era in terms of great fighters which isn't a knock against him as a fighter at all but it does weaken his standings when comparing to other fighters who fought in stronger eras.
Walcott was a depression era fighter. Malnourished and in a hurry to whatever exploitative job he could find to put food on the table.
