Points are points. I agree with your sentiment it's boring to watch, but no team is going to turn down their RWC trophy because they won it in a boring manner.
Oh in a big game for sure, but 2nd round of a small tournament it makes no sense unless this style is the way they want to play. Brumbies on the following night scored 9 tries so I guess it evens out lol. Let's see what this week brings
I tend to think that both teams realised that their attack was poor and that penalty goals were of a higher percentage chance of getting points. An ugly win v a loss by turning down points can be the difference between the top qualifier and home advantage and not.
