Sugar Ray Leonard Defeats Floyd Mayweather's Dad, But The Great Controversy Doesn't End

Surprisingly, Leonard beat Floyd Mayweather, not who many fans think of him.
In September 1978, the undefeated Leonard stopped Floyd Mayweather Sr. in the tenth round after dropping him twice in the eighth. Mayweather Jr. he was only a year old at the time, but the loss of his father remains an interesting piece of trivia whenever the two legends are compared.
Leonard spent little time rebuilding the monster. After defeating Mayweather Sr., he defeated Randy Shields, Armando Muniz, Tony Chiaverini, and Pete Ranzany. He then stopped undefeated Wilfred Benítez in the fifteenth round to capture the WBC welterweight title.
His willingness to take risks has set him apart from many champions.
Instead of defending his title, Leonard faced Roberto Durán in June 1980, losing a unanimous decision in a brutal fight. Five months later, he completely destroyed his original strategy, boxing circles around Durán until the Panamanian icon quit in the eighth round with the surrender of “No Más”.
Leonard kept chasing the top contenders. He stopped the undefeated Ayub Kalule before defeating the undefeated Hearns in September 1981. Trailing by all three points entering the fourteenth round, Leonard rallied to stop Hearns and unify the welterweight title.
His career nearly ended the following year when he suffered a blocked retina while preparing for a title defense. After a 27-month layoff, Leonard returned to stop Kevin Howard before taking another long break.
Most fighters would easily return to competition.
Instead, Leonard challenged middleweight champion Marvin Hagler after nearly three years out of the ring. Despite a long layoff, and an increase in weight, Leonard scored a split decision victory in one of the most contested championship fights in boxing history.
He followed that up by stopping Donny Lalonde to win the WBC light heavyweight title, while claiming the inaugural WBC super middleweight championship. Leonard later fought Hearns a second time, fighting to a draw after climbing to the canvas twice, before defeating Durán in their third contest.
His career ended with losses to Terry Norris and Héctor Camacho, finishing with a 36-3-1 record that easily earned him induction into the World Heavyweight Championship Hall of Fame.
Mayweather's career tells a completely different story.
He retired 50-0 while winning world titles in five weight classes. His resume includes victories over Diego Corrales, José Luis Castillo, Arturo Gatti, Oscar De La Hoya, Ricky Hatton, Juan Manuel Márquez, Shane Mosley, Miguel Cotto, Canelo Alvarez, and Manny Pacquiao.
Not every victory came without controversy. Many fans believed that Castillo deserved the decision in their first fight, while others scored the first goal of Marcos Maidana. Mayweather responded in both bouts by defeating each man clearly in the fights before closing out his career with victories over Andre Berto and UFC champion Conor McGregor.
Comparing the two legends ultimately comes down to what fans value most.
Leonard fought many Hall of Fame opponents in their prime, took big risks after long layoffs, and jumped multiple weight classes to chase the biggest challenges available. Mayweather has perfected the art of winning, solving every style put before him in 19 years of competition without a legitimate defeat.
If greatness is measured by taking on the strongest opposition regardless of risk, Leonard has a compelling case. Measured by continued skill, technical mastery, and undefeated record, Mayweather's argument is strong.
This is why the debate remains one of the issues of boxing, and this is why there is still no unanimous answer.
