Floyd Mayweather Has Nothing Left to Prove After Final Victory over Andre Berto

Whether you love him or hate him, there is no denying Floyd Mayweather has put together an amazing career. There is also no better time for him to call it quits.

The veteran boxer announced his retirement shortly after defeating Andre Berto by unanimous decision Saturday night, according to Kevin Iole of Yahoo Sports.

"You’ve got to know when it’s time to hang it up, and it’s my time to hang up,” Mayweather told reporters. “I’ve been in the sport 19 years and been a world champion for 18. I have nothing else to prove in the sport of boxing.”

There will be debates for eternity about where he ranks among the all-time greatest in boxing history, but that last sentence is tough to deny. He certainly has nothing left to prove in the sport.

Of all the stats you can use to evaluate Mayweather throughout his career, the most important number is zero. He has had zero losses in his 49 matches, and his latest win saw him tie another prominent boxer with this accomplishment:

He didn't always make a lot of friends along the way, but he certainly took on the best the sport had to offer in his generation. Wins over Manny Pacquiao, Juan Manuel Marquez, Shane Mosley, Ricky Hatton, Oscar De La Hoya, Arturo Gatti, Victor Ortiz, Miguel Cotto and many more prove he was capable of beating the biggest stars in boxing at the time. Those who question his matchups, including the final one against Berto, rarely have better alternatives in mind.

Sure, the 38-year-old boxer can add matches against quality competitors like Timothy Bradley or Amir Khan to his schedule. But none of them really have a chance to upset the champion, and the extra wins won't prove much about what we already know.

The biggest issue throughout his career was that his matches weren't interesting. One of the biggest stories after the win over Berto was an interaction with a fan during the match. 

Mayweather was an excellent defensive fighter who wasn't always aggressive for the knockout but knew how to win. The latest victory over Berto showcased his ability to avoid getting hit:

While this doesn't always excite fans, the object in sports is to win, and he did a lot of that. If he changes his mind about retirement and returns to the ring, he won't suddenly get any more interesting. He won't adjust his style to suit those watching along if it hurts his chances to keep his undefeated record. He is simply not Muhammad Ali when it comes to entertainment, and he shouldn't be expected to become him.

Of course, this boring style hasn't stopped fans from making him rich. According to Forbes, Mayweather once again topped the list of the richest athletes in the world, and this time it wasn't even close. He reportedly made $300 million in 2015, almost twice as much as his opponent and second on the list Manny Pacquiao ($160 million). Cristiano Ronaldo was third at $79.6 million.

There is clearly no such thing as too much money, especially in Mayweather's world. His newest $4.8 million car is proof of that:

The insurance costs for that thing might make him reconsider retirement, except for the fact that he has more than enough to last him and his family a long time. Unlike Mike Tyson and others, there is no reason to go on fighting just for a paycheck.

Mayweather is going out on top of the sport as the undisputed best pound-for-pound fighter alive. He also has a chance to leave healthy, something he described before the bout as an important factor in his decision.

"If you stick around anything too long, anything can happen," he told reporters, via Sky Sports. "I'm not really worried about losing, but I want to have a sharp mind. You can make a lot of money, but you still want to be able to talk, walk and have a sharp mind."

There are many who doubt Mayweather is really calling it quits, but looking at the facts, there is no reason to return. He doesn't need the money or the risk, and he has already shown all he can in the ring.

Whether or not you think he is the best ever, a few more fights will not change your mind.
