If something doesn't make sense it's most likely bullshi..The world's biggest sporting league is the NFL but they don't even have a development league. The NBA has the g league with teams located in small arenas & run on oily rag. According to you competition which once spanned Africa, Americas, Oceania & Asia was development comp. Good way to burn money - that's why its bs
Simple minds like yours just don't seem to grasp it. The NFL DOES have a development comp, it has lots of them, the collage system being the most profitable. Development leagues don't have to be run or controlled by the main body. Super Rugby in NZ is. That you are ignoring the simple fact that the All Blacks brand supplies over 90% on the income to NZR is why your "argument" is what is "bullshit" here. Super rugby provided, and provides content, but the simple fact is Internationals are where the money is made. Super Rugby just develops players for it.
