I have not been following this bunfight too closely. But from my perspective the national jersey has been devalued a fair bit already, by the weight of money on offer in the richer nations. And of course I am old enough to remember Des Connor.
At the end of the day, we are talking about sport, not armed conflict. Sport is about enjoyment, participation: even, dare I say it, entertainment.
Rugby is rugby, forget about what other sports do, we can chart our own course. If that means allowing a Test player from a Tier one nation to play for his country of birth at, or towards, the end of his career how is that more ridiculous than Bundee Aki, for example, turning out for Ireland?
