In modern times you have just Kevin McBride and Seamus McDonaghhttp://www.boxrec.com/list_bouts.php?human_id=3394&cat=boxer to compete with. Although McDonagh was really a Cruiserweight. Overall you have fighters mentioned like Tom Sharkey(who certainly has the best record of any Irish heavyweight and has a claim to having been heavyweight champion). Peter Maher also had a claim to being champion at one point, although certainly wasn't as good as Sharkey. Paddy Ryan(who's birthplace is just a half hour drive from my home town) was indeed World champion back in the bare knuckle days. When you bring in Irish Americans like Tunney, the standard improves a huge amount. If you're going with Irish born though Sharkey is the best on achievement, however I'd strongly back the modern day Rogan to beat any heavyweight from that era. So despite it seeming outlandish you can indeed make a case for saying Rogan's the best ever Irish Heavy.
I believe its quite an interesting topic if I may say so myself. You clearly have a chip on your shoulder or should I say a Jacket Potato, Whats your problem with London anyway? The Irish seem to love it.. They've set up many a caravan site near the east end.
John L Sullivan and Gene Tunney are just as legit Irish as Lennox Lewis is a brit. 2 Irish parents is good enough to qualify someone as Irish in my book. Just because they went to live in another country didn't mean they weren't Irish and didn't mean their children weren't Irish. Sullivans father was from Kerry and his mother was from Athlone. Tunney's parents were from Mayo. So take your pic of the 2 for the greatest Irish heavyweight of all time. After that Maher or Sharkey. After that there wasn't much more.
Sailor tom Sharkey has a fairly good claim to have held the lineal heavyweight title. He beat Jim Corbett and gave Jim Jeffries the toughest fight of his career. If we are including fighters who fought before the gloved era then your options are considerable. There were more American champions born in Ireland than America in the 19th century.
Tunney and Sullivan were both American in my book, born in America, raised in America and fought out of America. Lewis was born in the UK, left for a few years and then returned to base most of his pro career in he UK.
Jamacian parents. Raised with that culture. Left the UK when he was 12. Boxed for Canada at the Olympics. Fought out of the UK because the EBU/Commonwealth route was a career move that he took advantage of. 18 fights out of 44 constitutes most of his pro career? Between 1995 and his retirement, his last 18 fights, he boxed fought ONCE in the UK. He also fought once in Dublin and once in South Africa. 15 fights in america. He got his foot on the ladder with the EBU then ****ed off back to america when the uk had served its purpose. Sorry but thats just the way it is Lives in Miami now rather than the UK (funny that). So all that makes him british. But two Irish parents, being raised as Irish with an Irish hertiage and culture isn't enough for you to qualify either Sullivan or Tunney as being Irish. Sorry but by the same ropey criteria the brits claim Lewis, Tunney and Sullivan are just as qualified to be considered Irish.
18 out of 44??? Youre taking fights that he took in Vegas, New York etc to mean he wasn't fighting out of the UK at the time? Thats not how it works. During those fights he was living in the UK and was being billed as out of the UK (in addition to still being born in the UK!!), the fights just happened to be in Vegas or wherever. Is Hatton not British since he started fighting in Vegas? Lewis was born here, was billed, lived and conducted his pro career out of the UK. Thats a better claim to nationality to someone who wasn't born in Ireland, never fought there and never lived there as is the case with Tunney and Sullivan.
