Most experts are not predicting a close fight. Mayweather is considered the best boxer of his generation and is heavily favored in this fight; McGregor has never boxed professionally.

“I’m an old man. I’m not the fighter I was 20 years ago,” Mayweather said, going on to add that he isn’t even the same fighter he was 10, five or even two years ago. “But I got enough to beat you.”

White, Ellerbe, Showtime Sports’ Stephen Espinoza and MGM Resorts’ Richard Sturm all addressed the crowd, but Espinoza and Sturm were essentially booed off the stage, as the fans waited impatiently for the fighters to speak.

As McGregor joked, “I couldn’t hear anything those m—–f—–s said.”
