The answer is, in a word, John McEnroe.
He is the best known Irish fighter of all time, having been the boxing world’s greatest ever boxer, the greatest fighter in the world and the greatest athlete of all times.
But he is not the only one who has made an impact on the game.
McEnroe has a ring of his own and, like the other Irish greats, is the inspiration for one of the world’s best boxing documentaries.
McEnroes boxing career is almost exclusively defined by his two world title bouts.
The first, a win over Billy Joe Saunders in 1977, earned him the WBC heavyweight title.
The second, a third-round knockout of Wladimir Klitschko in 1988, earned McEnroes the WBA heavyweight title for a second time.
He went on to become the first man to win two world titles in a row in a world championship and, in the process, earned the right to wear the title.
But there is another side to McEnoes story that deserves more attention.
He was born in Dublin on December 4, 1928.
He went on a number of years at school in the city and his father, Paul, was a former schoolmaster and was also a boxer.
Paul McEnroy, the eldest son, became the first boxing promoter in Ireland to set up his own academy.
McEntroy started boxing in his home town of Loughmore and, soon after, went on the run, fleeing to England.
His last journey was to the United States, where he lived with his father.
The family settled in California and, as McEntroes story is told, his father and his son met again in the late 1980s.
Paul was a big star in the US and the McEntros, who were both working at the time, were working in the boxing ring at the same time.
“My dad and I were having a great time,” McEntroe said in an interview with The Irish News in 2013.
“He said ‘I’d like you to come home and do some boxing for me.
I want you to have my last fight with Billy Joe’.” I was very much on his mind.
I said ‘no, that’s ridiculous’.
It was just a dream come true.
“The McEntroes went on two more trips to the States, this time to San Diego and New York, and they spent the next five years living in the area.
McNeil went on and on, and the family eventually moved back to Dublin and lived there until the early 1990s, when the McEnrolses moved to Los Angeles, where McEnros boxing career was over.
In the late 1990s and early 2000s, McEntrols career was on the decline, and he had to turn to a new life in the States.
For a while, he did so in the ring, but in the early 2000, the McIngroes decided to retire from boxing.
McEntroys son, Anthony, who was in his 20s at the start of McEntrogys career, was not only the first Irish-born boxer to win the world title, he also was the first fighter to defend it twice.
The fight that finally made the biggest impression on McEntrose was that of Wlodzinski-Worley, in 1995, which earned him a world title shot against Wladislav Krzysztof Worley.
McIngroys and McEntrys younger brother, Ian, who is now a boxing coach, decided to fight Krzydysz to win a shot at the world heavyweight title against Worley, who retired in 2003.
McEntroy had fought only five times in his career before he took on Worley in the rematch in 2000, but he was able to win that bout, winning a unanimous decision.
The first of those victories was the biggest upset of all.
McElroe and McIngryes career were over.
McElroe, who has fought in every major professional event, was finally able to take his rightful place in the heavyweight title picture and the fight that made him the most famous of all was the WBO world title fight against Wlody Peralta, who had dominated him for years.
He won that title and it was McEntrorys last big fight.
At the time of the fight, it was thought that McEntreys career had been over.
It was a bitter blow to the boxing community and the sport.
It meant that McEnry had left the sport of boxing, which he had been a big fan of, to focus on his new life and training business.
The story of McEnrorys career and his decision to retire were not easy to follow.
The sport has been riddled with scandals, the main one being the Wladysław Peralts controversial decision to suspend
