What do you expect American boxing pundits to be talking /writing about? These guys are competing in a marketplace for eyeballs and clicks. Those eyeballs are primarily American and are interested in American fighters or fighters who are at least based in America, not some eastern European fucker with a ridiculous name or some Australian. So pundits and journalists and whoever are going to go with what their market wants because they're competing in a marketplace. If they can generate some hype by comparing a bunch of American fighters to each other in any kind of way then they're obviously going to do that because it's good for their business/career etc.
