<P> Five other teams have gone undefeated but featured at least one drawn match: Balmain (1915), North Sydney (1921), Eastern Suburbs (1936 and 1937) and St George (1959). </P> <P> Whilst no Rugby League team in Britain has completed the perfect season in the top flight, this has been achieved on two occasions in lower divisions, once in the 2nd division and once in the 3rd . Hull F.C. achieved this feat in the 1978--79 Season, where they won 26 from 26 games, gaining promotion to the top division for the second time in three seasons . This was also achieved by the Dewsbury Rams in 2009 during their Championship 1 (third division) season where they won all 18 games from a possible 18, winning promotion immediately after being relegated the previous season where they won just two games . Since their 2009 promotion, the Rams have so far stayed in the sports' second division, including two play off finishes . </P> <P> The New Zealand All Blacks were the first professional rugby team to produce a perfect rugby test season in 2013 . They successfully defeated France four times, Australia three times, South Africa and Argentina twice and also beat Japan, England and Ireland in their incredible winning run . They produced a record of 14--0--0, defeating the top 5 ranked teams below them in the IRB world rankings . England have matched this feat after producing a perfect test season in 2016 after recovering from getting knocked out of their own World Cup in 2015 . </P> <P> The Southern Hemisphere's principal team competition, Super Rugby, established as Super 12 in 1996 and later known as Super 14 before adopting its current name in 2011, has seen only one perfect season . The Crusaders, based in Christchurch and representing a large portion of the South Island of New Zealand, finished the 2002 Super 12 season with an 11--0--0 record and went on to win both of their finals matches to claim the season crown unbeaten . </P>
