Five division world champion Floyd Mayweather had a much tougher time than expected when he fought Youtube star Logan Paul last month in Florida.

Most had expected Mayweather to knock Paul out, but the exhibition fight would unexpectedly last the entire eight round distance. Pursuant to the rules of the exhibition, no winner was announced.

Mayweather, and many others, may have miscalculated the physical aspects.

Paul, 26-years-old, entered the ring with a likely 40-pound weight advantage and was physically much bigger than Mayweather in every aspect.

Mayweather, now 44-years-old and retired since 2017, was simply not the same fighter that many had remembered during his unbeaten run.

Jeff Mayweather - who is Floyd's uncle, a trainer and a former fighter - said his nephew's performance was due to the size and age disparity.

“I thought what happened could have happened because nobody else was thinking that the age, 44, was gonna show up. And plus, Logan Paul had Floyd about six-inches in height, probably about 40-pounds in weight. And he still an athlete. He was a wrestler, so I mean, don’t get me wrong and also he did a lot of holding. A whole lot," Jeff Mayweather said on The Champ and The Chump.

“All of that played a part. I think the biggest part is that people have the tendency to forget that Floyd’s not superman. He’s still an athlete, but he’s not the same one that you see now. he’s 44-years-old. He still did great for entertainment but I think a lot of people were disappointed because everyone thought there was gonna be a knockout.”

“I think he wanted to knock him out, of course, but he couldn’t. The guy was too big. He did so much holding and you know was strong enough to take those shots, and as soon as he got hit, he locked up. So that made the fight a little ugly. I still think if Floyd was younger, he woulda knocked him out.”
