World champion's absurd bet on Logan Paul
Former world champion Regis Prograis has put down $50,000 on Logan Paul to stun the world and knock out Floyd Mayweather today.
The YouTube star will walk into the Hard Rock Stadium in Miami as the monster underdog — but Prograis has spotted the biggest reason the undefeated boxing legend may meet his demise.
The former super-lightweight world champion says Paul's weight advantage of more than 15kg means he has an overwhelming advantage — and more power to put Mayweather to the floor.
After watching the weigh-ins this weekend, Prograis is convinced Paul can end Mayweather's 50-0 record — even though the exhibition fight does not count towards Mayweather's official record.
"Tonight is the night, Mayweather is going to lose," he wrote on social media.
"Logan Paul is over 30lbs bigger. They make weight classes in boxing for a reason. I'm putting up 50K that Logan will get the KO. You heard it here first."

His bet could see a return of up to $300,000 with Paul's odds being crunched in from as long as $6 with some bookmakers. With most of the money coming in for Paul, he is expected to start the fight as a $4 outsider.
Mayweather has consistently shrugged off questions about giving away such a dramatic weight advantage to an opponent.
A seriously ripped Paul tipped the scales at 85kg while Mayweather registered 70kg.
Mike Tyson said this weekend Mayweather will "kill" Paul ahead of their exhibition boxing match today.
The first fight on the Mayweather-Paul undercard didn't disappoint with Johnson landing some good shots in the early rounds before eating a heavy right overhand that left him crashing to the floor.
Maxwell's right-handed landed flush on Johnson's left cheek when the NFL star was exposed by poor footwork and an unbalanced stance.
Johnson was given a standing 10-count but was able to finish the fourth round, ensuring no official winner will be declared.
