I understand that, but look at major American sports: Football, Basketball, Baseball and Hockey have either 1.) Zero global following or 2.) Minimal global following in minor countries ex. hockey in Canada or baseball in the Dominican Republic.
And you can find good analysis and reporting on all these sports. Granted, I know being the world's largest economy helps, but it does seem like there is a market opening for good, strong analytical rugby reporting that aims to reach multiple nations/audiences.
