The variables between the two roles are highly significant. The Super rugby coach arguably has had more time with a pres eason and trials. It is different for the International coach.
This whole argument of Robbie Deans's tenure is subjective as it is based on people having different measures of success.
Ruggo, I hesitate to agree. Re your first para, you will recall that it was major S14 success that justified in the minds of all comers what an outstanding candidate for Wallaby coach RD would be. And an international Test coach in the SH has the major benefit of receiving elite players immediately post the S15 that have been hardened and well-prepared by over 16 or so games of international level rugby played by and against many of the world's best provincial teams and players. This is precisely what many commentators argue - with some justification - will aid the Wallabies capability and mindset as a result of the Reds S15 win this year.
So arguing that somehow the task of rapidly improving a team and creating a good w-l % ratio is somehow so much more
intrinsically harder and difficult for an international coach than it is for an S15 one, I don't buy.
And I don't agree that 'the Deans debate' is all totally subjective and 'based upon different measures of success'. Ultimately, in any major professional sport with very high $ overheads, large player $ payments, and a demanding public, any decent national code or team managing CEO will tell you that 'success' is pretty simple and objective, namely: you have to build a team (and related team brand) that wins many more games than it loses, does so in an play style that attracts large numbers paying fans (gate or TV), possesses a number of dynamic individual players that aid that attraction for fans, and thus in aggregate pulls in loads of sponsors, media buyers, and big crowds that fill stadia. If you don't achieve this, it's only a matter of time before (a) you get sacked and the team/club/code whatever broke or backwards and/or (b) the fan base gradually dies away and/or leaves for competing codes, and the public in general loses interest, and the downward spiral vicious circles start of under-investment, top player loss, weaker and weaker teams, etc. The modern sports' code's 'cycle of life' is actually remarkably objective and measurable, over time.
The notion that somehow the Wallabies can avoid these hard business and professional truths and we can wait years and years, and then more years, for the magic of 'development' to take its course, is reckless and inaccurate.
