Wales were abysmal for much of the game, SA really scraping the bottom too. It looked like one of those Wales England games where Wales are utter crap (TM) for 70, and no matter what the score is the match ends up really tight. Wales were the superior team by a fair margin last week, and had the brown end of the reffing stick on top, but contrived to lose. This was the adjustment demanded by the rugby gods, they were worse by some margin.
I don't think any other team bar maybe England would have had that game and result vs that SA team. France, NZ, Aus would have had higher scoring games, only Wales and England would have had such an uninspiring arm wrestle.
