This is why the wallabies struggle at scrum time!
In Argentina scrummagers are built from a young age, bring me back a time when the art form of the scrum can't be learnt in an off season by a back rower, but takes years of practice to develop.
You make a very good point @W88.
The time spent on practicing the "premier set piece" of the game seems inadequate when you think about the strategic importance of having a dominant scrum even at U19 level.
This is less to do with the issue of "converted back rowers" than it is about the amount of time and resources actually dedicated to learning and reinforcing scrum fundamentals and honing counter scrummaging tactics.
IMO this is a systemic issue with junior Rugby across the AU landscape and must therefore have a flow on effect to the senior/elite ranks.
My "back of an envelop" calculation indicates the following:
Based on each scrum play being calculated at a generous 15 seconds but in reality closer to < 8 seconds the following paints a dismal picture:
- Game time scrummaging: If approx 20 scrums are set during a normal game there is 5 minutes of practice X 10 games. I.e 50 minutes per season
- Training scrummaging 1 : approx 40/50 scrums set against a machine with no counter scrummaging ability. 12.5 Mins pw X 10 weeks =2 hours per season.
- Training Scrummaging 2: approx 20 live scrums set against 2nds or thirds = 5m pw X 10 = 50 mins per season
So the grand total is less than 3.5 hours of practice per regular season on arguably the most technically difficult and physically demanding set piece.
If it took Topo Rodriguez 300 pages to provide his thoughts on "Mastering the Art of Scrummaging" I'm not sure that 3.5 hours per season is enough to create master scrummagers post leaving high school.
