The influence of Macqueen's golden era and EJ (Eddie Jones)'s less golden era can't be underestimated. Most of the schoolboy, junior and club coaches have been heavily infected. I know that the teams I played in were all trying to play like the Brumbies in the late nineties and early 2000s. The young guys coming through do well to maintain any spontaneity by the time they get to S14 level and, in the case of Cooper in particular, everyone is crying for him to be more structured.
At the same time, across the ditch, the Kiwi youngsters were being inspired by the masterful, enigmatic Carlos Spencer, Christian Cullen, Jeff Wilson, Jonah Lomu, Umaga, Muliaina, Rococoko, Caucau, Sivivatu etc. The ABs and Blues circa 2003 were the best counterattacking, flair teams I have seen.
As you say in your article, our structure is one of our strengths but that means that the flair players have to fit in. It took Latham a long time to realise this and take his Super form to the test arena.
Deans is the first coach in a long while to encourage flair. Think Burgess who languished at the Brumbies for 2 seasons before being encouraged to chance his arm, O'Connor and Cooper in particular.
AAC (Adam Ashley-Cooper) is the real mystery to me. He can counterattack but, seemingly, was told to hoist bombs last season. Hopefully, this season, his wingers will work hard to get back to support him and Deans will tell him to run it if he has the support. Maybe its his judgement that is wanting? He seems to go well on the wing and at 12 (I cant recall him being dominant at 13) when he doesnt need to think too much.
