The problem with fans today is they don't have the historical context to understand how pervasive boxing really was in the old days and how diluted it's become today. The only way to possibly replicate the depth that existed in the old days is if you imagine all the best athletes of the nba and nfl growing up as boxers and then imagine them being 50 times more active than current boxers (fighting 3 times a month) and then reduce the # of belts from 4 to 1. Any top contender back then would be multiple weight class champions today easy. How many belts would Charley Burley, or Jimmy Bivins, or Billy Soose have in how many weight classes? Mayweathers accomplishments are wafer thin when you consider the arc of boxing.
This is perfectly said.
These other posters are dismissive of their schedules as if dismissing it makes this point invalid. This is what makes it a more difficult era - they were fighting with 4oz gloves, many times, most often bringing injuries into the fight against someone who could've had more rest than them. Their careers were essentially like modern day amateur careers but more brutal.
Taking a loss in these circumstances are thus not as big of a deal, either when assessing greatness. If Mayweather fought with this schedule, he would've had multiple losses, after all he went 84-8 as an amateur.
Interestingly enough, the best trainers and the skills were stronger before than they are now. There has been a degeneration of skill and learning.
I also contend that PED's, in its most potent form has been around since the mid 40's. Now we are getting knock off simulations.
Canelo was a great win because of the weight class, but he's not historically elite. Hatton again, a good fighter but not historically elite - possibly the most overrated fighter in this era.
Mosley was completely done, as was De La Hoya and Pac was also done by 2015. No way near the same whereas Floyd remained in considerably better condition than all three at the time he fought them. Why was anyone taking seriously a Pacquiao who had slowed down in 2012 and then was knocked out in the most scariest manner I've ever seen?
Marquez put on weight extremely poorly (went up two weight classes) AND was outweighed by 5lbs at the weigh in - that is not a fight worth mentioning in the slightest.
Floyd is a great fighter, he could've possibly beaten all three if they were prime-for-prime matchups, but he quite simply didn't get the opportunity/create the opportunity to face them then. Because of how past prime his best opponents were, it cannot be excused.
Seano and I have completely different views on greatness and our understanding of the sport.
I believe there's a double standard if you were to discuss the greatest amateurs of all time because it models old timers careers more - but they've never had a discussion with you about it I'm sure lol.
