Tuesday's fiery face-off saw the swaggering, cocksure McGregor strut on to stage confidently in a three-piece suit featuring pinstripes made up of an offensive two-word insult.
When Helwani probed McGregor on his potential return to the UFC octagon, the 28-year-old had an interesting response. The suited McGregor was the first to take the microphone, mocking Mayweather's decision to show up wearing a Stars and Stripes tracksuit, suggesting it was linked to the American's reported tax difficulties. McGregor declared to roars of laughter from the massed ranks of his green-shirted fans, crammed into the lower tiers of the famous basketball arena.
McGregor (0-0 in boxing) is fresh off becoming the UFC's first simultaneous two-division champion after claiming the lightweight title in the mixed martial arts promotion in November.
While McGregor is already red hot, Mayweather seems to be just warming up. "On 26 August, this man will be unconscious, he's too small, he's too frail". My job is to go out there and fight against the guy that's across from me. I've seen him do that a bit before and I can certainly relate to that because it's very hard to give speeches at press conferences. Mayweather has been here before countless times and isn't going to get out of character just because this is a unique event.
It was Mayweather's big gimmick, his pre-planned masterpiece - and McGregor pi**ed all over it.
The boxer (40) told his opponent: "I'm an old man - I'm not even the same man I was 20 years ago". I am pretty sure this is only the second time he has fought in 10oz gloves, the rest have been in 8oz. Or five years ago.
"Floyd has a problem, but doesn't want to come over and deal with it", Mayweather said h/t MMAJunkie. I know how he felt but he will get more comfortable, believe me.
The show from Mayweather didn't go unnoticed from fans either, who wondered if the IRS might be watching too... "They got entertained today by both competitors".
Malignaggi had been extremely vocal in his stance against the fight ever taking place and on top of that, was nothing short of condescending in expressing his opinion on McGregor's ability as a boxer. "Because that's how long I've been kicking ass", said Mayweather h/t MMAJunkie. "He's mad. I was calm, cool".
