The 40-year-old Mayweather, who fights the UFC lightweight champion in a mega-pay-per-view bout on Aug. 26 at T-Mobile Arena, looked like a 25-year-old at a workout Thursday to hype the fight.
Most boxing experts give Mayweather nearly every advantage and expect him to thrash McGregor and win the fight by a wide margin.
When the bell rings, he may not be equipped physically to deal with one of the best boxers of all-time, but McGregor is in his element every bit as much as Mayweather when it comes to dealing with the hype, handling the pressure and performing when the stakes are the highest.
McGregor, who praised Mayweather’s skill level, nonetheless predicted a knockout, within two rounds if they switch to 8-ounce gloves, he said.
That would be a feat of some note since Mayweather has only been down once as a pro, and it wasn’t really a true knockdown.
On Wednesday, the Nevada Athletic Commission is going to vote on a Mayweather request to switch from 10-ounce to eight-ounce gloves.
