Logan Paul apparently believes size will matter when he faces Floyd Mayweather.

Mayweather’s 26-year-old opponent said during an open workout Wednesday at the historic 5th Street Gym in Miami Beach, Florida, that he weighed 195 pounds, just five below his contracted maximum for their eight-round exhibition. He could out-weigh Mayweather by 40-plus pounds when they get in the ring Sunday night at Hard Rock Stadium in nearby Miami Gardens.

The 6-feet-3 Paul predicted that his highly unusual weight advantage will help him do what Canelo Alvarez and Conor McGregor couldn’t accomplish against the undefeated legend in their Showtime Pay-Per-View main event (8 p.m. EDT; $49.99).

“I’m just not them,” Paul said when asked specifically about Alvarez and McGregor. “I’m not going in there at 155 pounds. I’m not going in there with the fight meaning the entire world to me. I have nothing to lose. This whole thing is going to be fun for me. I’m going to play with Floyd – gonna dog him and hit him hard. I’m going to break him down physically, mentally, everything. I don’t like comparing myself to other guys. As great as they might be, I’m not them.”

The completely inexperienced Paul, of Westlake, Ohio, was wise to avoid comparing himself to Alvarez and McGregor.

Mexico’s Alvarez (56-1-2, 38 KOs) has evolved into a four-weight world champion who is commonly considered the best boxer, pound-for-pound, in the sport. The 30-year-old Alvarez hasn’t lost since Mayweather beat him by majority decision in their 12-round junior middleweight title fight nearly eight years ago at MGM Grand Garden Arena in Las Vegas.

And while McGregor might not have had any real boxing experience when Mayweather stopped him in the 10th round of their fight in August 2017 at T-Mobile Arena in Las Vegas, the brash Irishman was an elite-level mixed martial artist.

Paul lost his only professional boxing match – a six-round split decision to YouTube rival Olajide Olatunji, better known as “KSI,” in November 2019 at Staples Center in Los Angeles. This unprecedented step up in competition, even in a bout that doesn’t count, seemingly isn’t lost on the polarizing Paul.

“This whole thing is surreal,” Paul said. “Everything about it. I told my manager and we kind of had an inside joke that until I get in the ring with him, I didn’t think this fight was happening. But I think it’s safe to say that I can believe it now. I think it’s happening. It’s fight week. I can’t imagine Floyd would back out now, but who knows? Old man fakes an injury. Gets scared of the big kid. I’m excited.”
