An Australian columnist says the All Blacks dominance threatens world rugby.
Writing in the Guardian, Bret Harris says the success of the All Blacks might be wonderful for New Zealand, but questions remain whether it is positive for test rugby and the health of the game in other countries.
"This is particularly true for Australia, as the Wallabies play the Kiwis more often than any other team," wrote Harris.
"Never in the history of sport has there been an international team as dominant as the All Blacks. The New Zealanders have lost only two games since winning the 2015 World Cup - an exhibition against Ireland in Chicago and the second test against the combined might of the Lions, which they played with 14 men for almost three quarters of the game after Sonny Bill Williams was red-carded.
"While New Zealand has been the top country in world rugby for more than 100 years, the All Blacks have not always been invincible, especially at the World Cup from 1991 to 2007 when they were regularly knocked out in the play-off stages.
