McGregor and his coaches are coming in with high confidence though, and a gameplan that involves throwing out the conventional strategy used to fight Mayweather and delving into boxing history for a different, more rough house style of fighting.
Last November, Quigley said he'd be more than willing to lend his expertise to the McGregor camp if the fight was to happen, and now the US-based 26-year-old is predicting a stunning success for his compatriot. "I mean, just personally I went through it myself when I went to fight in Vegas on a PRIDE show, and they wanted me and Mark Hunt to fight MMA, and I wasn't qualified to fight a level of Mark Hunt in MMA", Butterbean said on MMA Junkie Radio. "I don't see a commission in the USA approving it, because of McGregor's lack of boxing matches". Mayweather was concerned enough about the possibility of McGregor fouling him that such language was inserted into contracts for this unprecedented showdown between an elite-level boxer and a star mixed martial artist.
"In the UFC, the stuff they go through on the ground with knees and elbows, everything, I think Conor McGregor is definitely going to open a lot of eyes". When you desperately want something, you have to go out of your way to get it. The chief executive of Mayweather Promotions, Leonard Ellerbe, was asked Wednesday night if the fight could gross half a billion dollars. "Fights like this will only help the sport grow", said Holm.
McGregor is the most accomplished and charismatic star on UFC's roster, holding a career record of 21-3.
McGregor has held UFC featherweight and lightweight title belts, but has never boxed in either professional or amateur settings.
According to UFC President Dana White, the answer is - so far, and for now - yes. "When you talk to this guy, it's fascinating".
Current odds, via Bovada.tv, have Mayweather as a -600 favorite-meaning you'd have to bet $600 to win $100. McGregor, is 27 and a southpaw.
