The saddest thing about Graham Henry's just published biography is that it tells us precisely nothing.
His eight-year tenure as All Black head coach was enormously successful in terms of results, cultural changes and high-performance breakthroughs and yet none of this comes through.
What we have is one giant whinge and shameful claim from an event five years ago: an event that was rendered irrelevant the instant the All Blacks won the 2011 World Cup.
In beating France 8-7 last year, the All Blacks earned themselves and Henry the redemption they craved. Wayne Barnes could be ignored - left to wallow in his mediocrity ever nervous about when the IRB would get round to giving him the chop.
Henry, one of the greatest rugby brains of this or any other time, could have used his book to offer just a fraction of his insightful and analytical mind. From the comfort of his new found place as the nation's most loved pensioner, he could have been magnanimous, open, honest and accountable for the failure of 2007. And why not? Because, that, as far as everyone else can tell, is the truth.
