Last night, five-weight world champion Mayweather announced he will be taking on Paul in an exhibition fight on 20 February 2021.
YouTuber turned boxer Paul, 25, is 6ft 2 and weighed in at 199.4 lbs for his professional defeat to KSI in a bout that happened at cruiserweight at the Staples Center.
Mayweather is considerably smaller at 5ft 8 and 147 lbs - which was his weight for his destruction of 20-year-old Japanese kickboxer Tenshin Nasukawa on New Year's Eve 2018.
But this story from promoter Dmitriy Salita suggests that 'Money' has no problem mixing it up with those bigger and stronger than him.
In the early 2000's, a heavyweight rocked up to the facility where Mayweather was working on his craft and in next to no time the two were slugging out in the ring.
The unnamed fighter was more than 60lbs than Mayweather but spurred on by his trainer, late uncle Roger, hix class shone through and he promptly dropped the heavyweight.
"When we were in the gym, it was like after one of Floyd's fights. We were just hanging out. This guy comes into the gym. A heavyweight. He's like, 'I want to get some boxing'," Salita recalled to Elie Seckbach, as per World Boxing News.
"He was just like talking a lot of smack and nobody had gotten picked to spar, so Floyd was like, 'Leonard (Ellerbe) get my stuff from the car!' "Leonard went to the car, got his gear and Floyd got in the ring with him (the heavyweight).
"Thirty seconds in and going his (famous) shoulder roll and that, he hits this guy with a body shot and drops the guy. He was a heavyweight and the guy could fight. "Then Roger said, 'if you're a real fighter you get in there and you fight'.
And that's what Floyd did. It takes that spirit. Training since you are a kid, to have that kind of mindset to be a great fighter."
Details for the Mayweather-Paul fight are minimal at the moment, though we do know the bout will cost at least $24.99 on pay-per-view as part of a pricing structure released.
The longer fans leave it, the more expensive it will be to watch.
