Mayweather confirmed his status as the finest boxer of his generation and an all-time great by outclassing Manny Pacquiao in an unanimous points victory in Las Vegas on Sunday.
Mike Tyson and Lennox Lewis were among those to acclaim the 38-year-old’s technical masterclass, but there were also plenty of dissenting voices led by Oscar De La Hoya who tweeted “Sorry boxing fans”.
Mayweather’s defensive, counter-punching style is not to everyone’s taste but it made Pacquiao – considered the greatest threat yet to his unbeaten record - look ordinary and the eight-weight world champion later complained he had been carrying a shoulder injury.
Whether Mayweather observes his vow to retire after his 49th fight in September - Britain’s Amir Khan and Kell Brook are potential opponents – is doubtful, but his father and trainer warns his skills should be enjoyed while he remains active. “I just know my son should be treated better. Maybe the truth is that he’s too good for his own good,” Mayweather Sr said.
“Sometimes you’re so good but people don’t appreciate it until it’s all over and done. And then they’ll appreciate it, but it will be gone.
“All he can do is beat the people of his era. If he stopped right now, he’s not got anything to prove. He’s done it all.
“Floyd is a little man like Pacquiao. He’s gone up and whooped the light middleweights. All of them. The people who were booing him at the fight were just a bunch of asses. People don’t know boxing, that’s the problem.
“Floyd is just like me, he never gets an accolade from anybody. I never get the type of accolade (Pacquiao’s trainer) Freddie Roach is getting and Freddie Roach is a joke, blowing smoke, with no hope.”
A rematch of the richest fight of all time appeared inevitable before the first instalment, but Mayweather’s mastery of an opponent he dwarfed in the ring has made it all but impossible to justify, even allowing for Pacquiao’s torn shoulder.
“Pacquiao would never beat him, believe me, because of one thing – he doesn’t have this (pointing to his head),” Mayweather Sr said.
Mayweather plans to surrender all five of his world titles after deciding the climax to his unbeaten career in September will be fought for prestige only.
Mayweather insists the decision to vacate is motivated by the desire to help others, although he would also save a considerable sum in sanctioning fees.
“I decided backstage that will I will give them up. My last fight will still be a championship fight over 12 rounds, but there won’t be any belts. I’ll talk to my team and see what we need to do. Other fighters need a chance. Give other fighters a chance. I’m not greedy.
“I’m a world champion in two different weight classes. It’s time to let other fighters fight for the belt.” Mayweather refused to discuss potential opponents for his final outing, demanding that he be given time to “enjoy my victory”, and is adamant he will not attempt to eclipse Rocky Marciano’s 49-0 record.
Viewing boxing as merely work and more comfortable discussing his material wealth than his exploits in the ring, the Atlanta Olympics bronze medallist insists he has no affection for the sport or desire to supplant Marciano in the history books.
“It’s about working smarter, not harder. We believe in taking as few punches as possible,” Mayweather said.
“I don’t want to start taking abuse to my body when I’m almost 40. I want to have all my faculties. I invested my money extremely well, so I could retire from boxing today A-ok.
