Scrummager- would love to say England, but we haven't been tested against the AB's so I think NZ.
Open Play- Again would love to say Fiji as I am a huge fan of Pacific Island rugby, but when it comes to throwing the ball around, NZ have the quality backs to do it.
Best Lineout- S.A. no question I'm afraid
Tactical kicking- I can't say really- Argentina in the World Cup were spot on at this, so I'd have to say the Puma's, but S.A. were also awesome at this. Anyone who argues that the S.A. kicking game is poor is a bloody fool. Montgomery and James are class backs when it comes to this area of the game.
Best defense- Another toughie. The Welsh are very good at defending, but what do you expect with such a brilliant defense coach. Then again, there is an argument above this post saying that teams with poor defense do not win World Cups, which is so blaringly true. S.A. for now, Wales for the future on that one methinks.
What I find funny is that a lot of these assets could be damn near perfect if there was another individual involved. OK, imagine S.A. lineout with Parisse, or NZ scrum with Sheridan, or S.A. defense with Shaun Edwards. Not the discussion, agreed, yet quite an odd arrangement.
