Mayweather took a chance on Davis when he was a young boxer with less than 10 fights. The gamble paid off big time. Davis shot to stardom, becoming one of Mayweather's best investments.
But things aren't rosy between them anymore. They've been taking subtle jabs at each other online, showing their relationship has soured beyond just business.
Mayweather gave Davis some advice on his private jet. He said:
"Do what makes you happy. I made over a billion dollars because I did what I wanted to do. Do what you want to do."
Mayweather credits his success to running his career his way.
Now, Davis might fight Jake Paul. Boxing fans think it's a weird match-up. The guys are 30kg apart in weight. Luke Thomas, a boxing commentator, doesn't like the idea:
"In general, Jake Paul's fights are s***. Everyone knows the truth. If they were the same size, Gervonta would knock him out quite easily. But they are not. There is a huge difference. [...] Again, who has more boxing skill? Gervonta by a long shot."
If Davis takes this fight, it could mean he wants to retire undefeated. He might move to exhibition matches to make more money and avoid tough fights like Shakur Stevenson or a rematch with Lamont Roach. But he risks leaving unfinished business in boxing.
Some boxing experts are upset about this potential fight. One veteran journalist calls it a sad sign that American boxing is falling apart.
Davis, now 30-0, won the National Golden Gloves Championship at 18 in 2012. Paul started on Vine in 2015 with millions of followers but no boxing experience. He's gotten better at boxing over the years and wants to win a world title.
But a fight with Davis won't help Paul's quest for a title. It looks more like a cash grab than a step towards greatness. Some worry this match-up shows American boxing cares more about money than quality fights.
