Wow, ok dude. First you throw up sarcasm, when you know perfectly well we played Canada and Namibia with a complete second team, who use the same defensive system. Then you throw Japan in the same sentence, when the entire world couldn't stop raving about their pace and offload game, nevermind the fact that they beat both Ireland and Scotland to top their group, and scored a combined 5 tries in those games, and had the entire world support them... yet they couldn't score against us with almost 80% posession for 40minutes. Then you think playing a full strength NZ team in NZ means nothing because it's a WC year, so of course that doesn't count. Then you finish off by saying we are actually just looking better defensively because everyone else are not? REALLY poor reasoning.
The Springboks can only play what is in front of them, and in that light, defensively it's been near flawless, for the entire year...
