I won't put money on Logan Paul.
Before Jake Paul fight against Ben Askren, nobody believed that the kid could win a formal UFC fighter or at least pro athlete. People only talked how a person that trained martial arts for his entire life would beat a youtube parrot. Then happened what nobody expected. Not only Jake won, but he TKOed Askren
I would not bet on Logan winning, but would consider betting on a draw or no contest. On this match, Mayweather is known on his craft and is undefeatable. That's why for me, this is a game for Mayweather and even how hard Paul would do, he's not yet on par with Floyd's experience.
I agree that this is a game for Mayweather. I think this is a charity fight and not a title fight. If you are going to ask me then everybody would be placing their bets at Mayweather and that this match is not really a match worth betting for. If you are going to bet for Paul, then your bet is already a high percentage of losing. So I am not sure how this fight will go but the bet would not who will win, but rather what round Mayweather will be able to knock out Paul.
I never heard Mayweather do an exhibition fight for Charity, this guy is named "money" for a reason, he wants to accumulate money and that's it. It's like a regular fight in his professional boxing career where he makes bigger money than his opponent, and all his earning is just for him.
