....I'm not at the stage of calling for sackings, but I'd suggest there are a couple of things to consider: Are the current coaches performing well?If not, what can be improved? If they are not capable of doing it, are there other alternatives available? Ideally things will improve, but even if they don't we could be stuck if there is no alternative available.
(*Please forgive long post, I am trying my best to contribute thoughtfully to the debate ;-) ).
Like us all, I have been thinking about this. When you look over the panoply of top line coaches in many team sports, you tend to find that no one is good at every core dimension of coaching. These coaches tend to be excellent in one or more of, but not all of: (a) team selections/composition over time, (b) individual player development and skills, (c) game planning and detailed tactics, (d) team culture/mind/psychology/attitude/'right stuff', (e) physical conditioning and endurance. (You could finesse all these terms to your personal taste, but hopefully you know what I mean.).
What I think has happened with Deans _may_ be this: NZ is by history naturally stocked with elite rugby players many of whom come ready-made with the 'right stuff' as per (d), it's built into the DNA of the game there and the entire AB tradition and its link with cultural identity in NZ. Coaches may need to encourage this 'stuff' and build on it, etc, but they don't need to be expert in creating it, finding it, culling the non-stuffs, and constantly re-inforcing it. NZ rugby coaches thus, by natural evolution, tend to have skills honed and directed more to (a) and (c), than all of the others above. And these coaching skills are often flattered and enhanced by the country's natural propensity to generate the right feedstock of (d), in quantity. The Crusaders' and ABs' wonderful histories could not be better examples.
I would argue that Australian rugby, for many varied reasons (a long post needed for analysing that), has, in the last 10 years, thrown up less and less elite players whom _naturally_ come to the top game with 'the right stuff'. We know what we mean by 'the right stuff': intensity, high physical courage, 'mongrel' when needed, always-on aggression (right sort), absolute commitment to attack, 80 mins mindset, incredible jersey-pride, etc. Whatever, this 'right stuff' is actually more and more critical to winning in top line rugby, not less so. Doesn't mean that player quality and experience is not hugely important, but you need the right deeper attitudes and team mind to go with all that, or you get loss-inducing inconsistency within games, or from one game to the next, or you handle pressure poorly with higher error rates as the mental attitude is not hardened.
Now, with hindsight, I would argue that probably what the Wallabies most critically needed from 2008 (or earlier) was a coach that was excellent in culling and deeply rebuilding the core attitudes of the Wallabies, and forcing a team that could deliver this 'right stuff'. And that is precisely what has not happened in the 2008-2010 journey, and why we still see such core problems of intensity and application today. And I don't think Deans has this skill (and, as above, with his history he probably didn't much need it), I think his skills are far more in (b) and perhaps (a). This is NOT to argue that 'promoting talent and youth' etc and better game plans and back line ingenuity and handling skills etc had no role in what was needed in Wallaby land.
But the central point is that there is no use having a bunch of capable players and tactically brilliant schemes if they cannot consistently bring the right fundamental mental strength and attitude to the park for 80 mins when needed. In fact, what I sense is that Deans has recently become markedly less confident in directing the Wallabies because he has realised that, whilst he has achieved some growth in player competence and talent, he has not at all corrected severe flaws in the Wallabies' attitude and mindset. And the result is just a kind of more youthful re-run of 2005-07.
It may well be that RD has had a collision in time with Australian rugby history and both parties are concussed in incompatibility and with a fit that may never have been destined to work.
