My great grand mother was born a slave and that is part of American History, dude. You can have your own definition of history but it only means something to you, dude.
Damn near everyone in America knows who Roy Jones is, even little kids born after the Tarver fights. He's very well known even among casuals, they can't necessarily tell you details about him but the know his name.
Well, we are going off topic. I guess you are right, it's kind of a subjective appreciation. Anyway, you think it's history now, I think it will be history in a while, anyway, history in the end. Now on topic, RJJ imho is still popular, maybe not among the young casual generations, but he is among the old casual generation and the new hardcore ones. He's one of the funniest fighters to watch I've ever seen, his fights make aficionados, you watch him you love boxing instantly.
He's only a boxer, no casual remembers boxers known for just being high quality boxers. People like Ali or Tyson are only remembered because of what they did outside of the ring, positive or negative. Also boxing isn't the type of sport where there's matches every day or every week so people probably forget about these boxers after a while.
All the present nations in the Americas have shorter histories than those in Asia, Africa and Europe.
True, that's because he has remained around as an announcer and references are constantly made to his former impressive boxing skills. He has also been active rather recently in some fights. Nothing like his former performances but it has helped keep him in the public eye.
Calzaghe was used as an example lol. As great as Cal is, here in America he could walk the streets and people wouldn't know him. Roy Jones Jr is more known in the UK than Cal is in America.
US has roughly 6x the population England has and is MANY, MANY times bigger area wise. You do realize this right?
