Wellington –

Rugby Championship organizer SANZAAR says it is open to hosting the competition in a centralized location again after this year's edition was reduced to three teams and played entirely in Australia due to the COVID-19 pandemic.

The late withdrawal of world champion South Africa left hosts Australia, New Zealand and Argentina contesting a Tri-Nations format but the competition normally involves all four sides playing home and away against each other.

New Zealand won this year's title after Australia and Argentina were deadlocked 16-16 in the final game in Sydney on Saturday.

SANZAAR Chief Executive Andy Marinos said the partnership between the four unions recognized the centralized format could work again if needed.

"The concept of a centralized (Rugby Championship) is very possible," Marinos said in a statement. "The prospect of double-header rounds (is) a huge benefit for the local fans and wider broadcast audience across the four geographies."

With the Springboks pulling out due to concerns about player welfare, the competition lost some of its luster but still delivered a shock for the ages with Argentina's first-ever win over the All Blacks in Newcastle.

The Pumas' 25-15 victory over the three-times world champions came after Mario Ledesma's side had endured a torrid buildup to the competition, with more than a dozen players and support staff testing positive for COVID-19 in Argentina.

They also endured months of isolation and numerous quarantine periods in South America and Sydney.

"The performance of the Argentinean team is quite remarkable if you think about the amount of time they have been away from home and the various quarantine protocols they had to endure," Marinos added.

"It is a testament to their team environment, strong management and a desire to want to play in a very difficult year for the sport."

Apart from that massive upset in Newcastle, however, few of the games delivered great performances or provided a spectacle for the fans.

Defense dominated, with the Pumas in particular content to live off penalties. Despite being regarded as one of the more enterprising international sides in recent years, they scored just two tries in their four games.

The All Blacks and coach Ian Foster came under intense scrutiny after losing successive games, 24-22 to the Wallabies in Brisbane and then to the Pumas.

They won the title on the back of a 43-5 win over the Wallabies in their first game and a 38-0 thrashing of the Pumas in their last match to alleviate some of the pressure from fans and media back in rugby-mad New Zealand.

Wallabies coach Dave Rennie faces the toughest off-season of all three coaches, still unsure if his players have the instinct or rugby intelligence to win close matches.

While he has unearthed some promising young players, depth of talent will test his planning for the foreseeable future.
