QH: The Wallabies play all of 2013 has been littered with serious errors of defensive structure, realignment and individual defensive confusions and incorrect defensive reads. It's consistent, its fundamental and contributes hugely to game losses and of course an opposing team's useful calculus that it's likely the Wallabies will make defensive errors, etc.
That after eight 2013 Tests we still have these chronic problems shows the team very clearly lacks a top-flight defensive coach with deep experience of this crucial technical area, and how to train for excellent defence, and how to design effective defensive structures for the whole team, and so on.
To the best of my knowledge and desk research, Scrivener - the Wallabies defence coach - has had no defined, specialist experience in the area of defence.
Whatever, he's made made absolutely no improvement in Wallaby defence in the time he's had this role.
