And people in the Boston area most certainly will be filling up the numerous Irish bars around the Hub to cheer for McGregor.
The showdown between undefeated boxer Floyd Mayweather and mixed martial arts champion Conor McGregor on Saturday may be poised to become the richest fight of all-time but despite the hype had yet to generate a sellout.
There will be no titles on the line, only a gaudy "Money Belt" with a strap made from crocodile leather and featuring 24 karat gold, 3,360 diamonds along with sapphires and emeralds, but much will be riding on the result.
Just hours before the fighters were to step into the ring, the T-Mobile Arena website had tickets available in every section except one in the upper bowl and the floor with prices ranging from $2,500 to $10,000 for ringside.
Mayweather has repeatedly insisted Saturday's fight will be the last of his decorated career, and despite the likelihood his ability will make their match-up highly non-competitive, his impressive shape suggests he has thoroughly prepared.
But Trudeau doesn't think it's going to be a spectacular fight to watch.
Smaller bets are going on McGregor with UFC fans backing up their loyalty with their wallets. "Las Vegas is Ireland now".
"You can't beat us - we've already taken over", McGregor bellowed.
U.S. extends sanctions against North Korea
He said on Tuesday that, since there have been no provocative actions by North Korea since the U.N. Russian Federation has also not been a good faith partner on these issues.
"I will go forward and put the pressure on and break this old man", said McGregor.
'I'm going to be a lot bigger than him tomorrow night, maybe closer to 170'.
Aside from McGregor's cocky assurances there is little in the tale of the tape to tip an upset.
I would argue McGregor doesn't even have a puncher's chance given Mayweather's first interest in defense.
Mayweather, who retired unbeaten in 2015 with a ideal 49-0 record, is widely expected to inflict a one-sided defeat on McGregor, a two-time world champion in MMA's Ultimate Fighting Championship who has never boxed professionally.
McGregor's potential to register the biggest upset in boxing history rests largely with the intangibles. And judging purely from a technical perspective, the contest would be an intriguing one, given the fact that one is a professional boxer while the other is an exponent of MMA.
"Of course I've got Floyd Mayweather", USC linebacker Bryson Allen-Williams said. "After 21 years I've been hit with everything and I'm still right here".
