Cape Town - Springbok coach Heyneke Meyer is happy with the strides his team have made in last few months.The Boks produced arguably their best performance in Meyer's tenure when they demolished Argentina 73-13 in their Rugby Championship opener at FNB Stadium on Saturday.It's not only the scoreline which satisfied the coach, but also the way all the structures fell in place to produce the desired result.GALLERY: Top 10 Rugby bad boys"What made me very happy is the fact that we won eight out of eight scrums and 15 out of 15 lineouts. I think we're starting to reach the point where we can compete with the best in the world up front," Meyer told the Beeld website."Our defence is better than what is was in the beginning. I'm also happy with the way we're now competing on the ground - and this team is very dangerous when it gets quick possession."Out tactical kicking is improving, and there are also more experienced players and continuity in the team as was the case on last year's tour to England."Our bench has also become very strong - therefore I don't view them as reserves but impact players," said Meyer.But the coach has warned his team not to underestimate Argentina this week."We have to keep our feet on the ground, and focus match for match. We used the wrong game plan in Mendoza last year (when they drew 16-all). We tried to play attractive rugby. That's why we were clinical on Saturday."The Boks are currently in Buenos Aires preparing for Saturday's clash against the Pumas in Mendoza.Kick-off is at 21:10 (SA time).
