"Mayweather's going to teach him what boxing's all about". Mayweather Jr. tipped the scales at 149.5 pounds, just above his usual 147 pounds at welterweight, while McGregor came in at 153 pounds.
"As a regulator, I take offense to the fact that we're approving this fight for fiduciary reasons", Bennett said.
For Mayweather it will be the culmination of a life's work, a chance to surpass former heavyweight great Rocky Marciano, who retired with a ideal 49-0 career record.
But I'll give Mayweather's interest and dedication in boxing the benefit of the doubt here, and say he's going to underline his belief that his sport is the king of combat sports.
74 inches - Conor McGregor's reach when throwing punches - a two-inch advantage over Mayweather. "I don't see him lasting two rounds, I feel I will have the decision to end it inside one".

McGregor is expected to be significantly heavier by the time the two fighters enter the ring, and he said of his undefeated opponent, who fights for the 50th time: "He's full of water: that's the worst shape I've ever seen him in".
He also walked down Shane Mosley. Mosley is a future Hall of Famer.
Mayweather, though, has seemed anything but fearful in the lead-up to this mega-fight. I wouldn't be surprised if he tries to blast out McGregor early, which could prevent the audience from seeing the extent of McGregor's incompetence.
Despite McGregor's mixed martial arts expertise, he's yet to compete with a professional boxer in a sanctioned fight.
Doing so might even earn him some undue credit for the farcical win. Not by a long shot. Referee Robert Byrd better be alert.
The party shifted into high gear after Friday's weigh-in as thousands of fans, many wearing emerald green or wrapped in Irish flags, spilled from the arena on to the Strip for night of booze fuelled revelry that carried on into Saturday. Otherwise, he'll have a tough time hanging with an elusive defensive maestro like Mayweather, who should win handily.
