After 49 career professional fights, Floyd Mayweather Jr. is retiring as one of the best boxers to ever lace up a pair of gloves.
Following his unanimous-decision victory over Andre Berto on Saturday night, Mayweather reiterated to the boxing universe that he doesn't plan on returning to the ring.
"I've accomplished everything, there's nothing else to accomplish," Mayweather said, according to the Guardian's Bryan Armen Graham. "Money don't make me, I make money."
Mayweather added more, per ESPN.com's Brian Campbell: "You have to know when to hang it up. It's my time to hang it up. ... Nothing else for me to prove in the sport of boxing."
The 38-year-old legend did it all as he mowed down the competition en route to a perfect 49-0 record. He retires as a former five-division world champion while arguably still being the best pound-for-pound fighter in the world.
Although there is little doubt Mayweather could still put on great fights and draw tons of money, this retirement has been over a year in the making. Prior to his second fight against Marcos Maidana in September 2013, Money announced his intention to retire at the conclusion of his deal with Showtime and CBS, according to ESPN.com's Dan Rafael.
"I only got two more fights left (after Saturday) and after the next two fights I just want to build the Mayweather Promotions brand," Mayweather said last year."My next fight is in May and my last fight is in September, so a year from now will be my last fight."
While Mayweather is indeed retiring, his announcement didn't come before he finally stepped into the ring with Manny "Pac-Man" Pacquiao. Although Mayweather was often accused of ducking the Filipino star over the years, he finally helped give the fans what they wanted.
In addition to that, Mayweather proved his worth by easily defeating Pacquiao in a 12-round decision. The so-called fight of the century wasn't always exciting, but Money put on a clinic that will forever be remembered by boxing observers.
Prior to his clash with Pacquiao, his father, Floyd Mayweather Sr., suggested that retirement should be imminent, per David Mayo of MLive.com:
He doesn't have to fight if he doesn't want to. If he'd have another fight, if I was him -- me, myself -- I wouldn't fight nobody (tough). There's no reason. For what? I wouldn't care if the people came or not. You've done made all the money you're going to make anyway. It don't get no bigger than this right here.
Many were skeptical of Mayweather's announcement in 2013 since he has stepped away from the sport before only to eventually return. After defeating Oscar De La Hoya in 2007, Mayweather retired briefly. He returned to fight Ricky Hatton but retired once again after that.
While that retirement seemed permanent, Mayweather eventually returned 21 months later to decisively beat Juan Manuel Marquez in 2009. Mayweather would then go on to beat many of the biggest names in the sport, including Shane Mosley, Miguel Cotto and Saul "Canelo" Alvarez, among others.
Mayweather has done it all, though, and even before he signed on to face Pacquiao, Mayweather Promotions executive Leonard Ellerbe claimed Money had no challenges left to overcome, per Rafael:
I'm happy. He deserves it. He's put in the work his whole career. Grinding, done everything the fans have asked of him. He's had a remarkable career. It's time to hang 'em up. Made all the money you can make. What else is there to do in the sport? There's nothing else to prove.
What Mayweather lacked in power during the second half of his career he more than made up with lightning-fast speed and quickness. He will also go down as one of the greatest defensive fighters to ever step foot in a boxing ring, as he stifled almost everyone he faced in that regard.
While Mayweather will no longer be an active competitor, one can only assume he will be heavily involved in boxing. Mayweather Promotions and The Money Team have taken off in a big way, and it isn't difficult to imagine Mayweather becoming the top promoter in the sport.
He kept boxing afloat for so many years as a fighter that it is only fitting for him to continue doing so even after his career is over. The possibility of Mayweather returning to the ring will always be on the minds of boxing fans, but it feels like he is serious about stepping away for good this time.
If that is the case, then it is truly the end of an era in the sport of boxing.
