If you're talking about the die-hard fans of rugby, the first one "Rugby's Die-Hard Fans" is correct. The apostrophe after the "y" in Rugby makes it possessive, indicating the die-hard fans are fans of rugby. Rugbys would be plural, but the word makes no sense: you can't have multiple rugbys, since it's a sport, and not an object to be duplicated. You can have multiple rugby games, for example, or multiple rugby balls, but not "rugbys."
i think so there are 60 billion fans of fans
tens, hundreds, thousands, millions of hunger game fans worldwide
11 MILLION
