Bok Rucking must Improve or early World Cup Ticket home

The reality is that Argentina are just better scrummagers team than the Boks- regardless of any current prop we could select. 
It was perhaps the worst Bok scrumming performance in history- even worse than last year's humiliations to Argentina. Fortunately we could avoid Argentina at the world cup. They will probably be the best scrummagers at the tournament- depending on what team is available for England. 
However the game was lost today at the rucks, more than the scrums. We just got slow ball from the rucks, and the reciever would often isolate themselves. 
What is worrying is that we had a backrow of 3 loosies that have experience playing as specialist 6 fetchers- and we still could not control the rucks.
Argentina like Northern Hemisphere teams have some very effective players at the breakdown that can slow down possession. Last years tour was the same story. We let their forwards all over our ball with slow recovery. 
It is not clear who will play at 6 in the world cup- but it will probably be Louw, with Schalk at 7- and hopefully Thor at 8. 
If we cant protect the ball at the ruck in this world cup were are screwed. If we get bulled at breakdown- their is at least 7 teams that could beat us at the World Cup in a knock out game.
Our backline can score tries but we need quick ball. We should also be able to get a few lineout tries with Matfield back to organise the lineout driving mauls.
With Willie at 15 with quick ball we could potentially outscore most backlines at the world cup.
