Quote ="Dougy"You are obviously differing a robin robin tournament and league structure.
The RU World Cup needs playoffs because not every single team in the competition plays each other. In round robin tournaments all competing teams play each other at least once and each other the same amount of times. Once that is complete the team with most win/points is declared Champion. There is then no point in making them playoff off against each other again!'"
So, according to you a play-off and GF is needed to declare a champion only when clubs dont play each other the same amount of times. For the past 15 years Super League has not had a league season where clubs play each other the same number of times.
Though of course many competitions do play each other the same amount of times and have play-offs and a grand final to declare the champions.
In fact whether they play each other the same amount of times or not, it is very difficult to find a club rugby competition anywhere which doesnt decide its champions by a grand final.
What we can see from this is quite obviously, that whether you play each other the same amount of times like the Currie Cup, Aviva Premiership, Pro-12, top 14, Elite One, or you dont like the NRL, Super Rugby, NZ National Competition, and Super League, club rugby competitions throughout the world, invariably, decide their champions by a play off/Grand Final.
