(Reuters) - Former All Blacks coach Steve Hansen believes the proposed World 12s tournament would revolutionise the sport and that the Six Nations rather than global governing body World Rugby will determine whether or not it happens.

The new 12-a-side rugby union tournament https://www.reuters.com/article/uk-rugby-union-12-idUKKBN2G31BY -- similar to the IPL in cricket with players from across the globe playing for eight franchises -- was launched last week with the goal of bringing $344 million into the sport over the next five years.
