Some rugby blogger with too much time on their hands went through and calculated the competition table as if it was played under the old format. So each team in each conference only played each other once (being the opposite game to 2010) and eliminated the 'conference' table rankings. The only thing that couldn't be accounted for was the teams that sides didn't play this year. The Rebels were removed altogether.
The end result? The top four were exactly the same. As were the top six. Just slightly different in order. Cru, Stormers, Reds, Blues, Sharks, Tahs. *Note the 'saders ended up on 36 points vs Reds and Stormers on 32, however they played an extra game as they didn't play Rebels this year. The author of the article neglects that in his praise.
In fact all positions were fairly similar with only 8-12 changing and only by 1 or 2 spots.
While this is obviously not an exact science, it shows that the 2 games against the easy Oz teams had little impact on the comp overall.
