The most successful coaches of all time in sports

As much as we’d like to deny it, the most successful rugby union coach of all time is arguably Sir Graham Henry, coach of the All-Blacks from 2004-2011. He coached the New Zealanders to 88 wins from 103 tests; a staggeringly impressive winning ratio of 85.4%.

Naysayers might argue that he took the reins of a country with one of the most naturally strong pools of rugby talent in the world, and they’d be right.

However, his ability to take that raw individual strength and talent and turn it into a shockingly disciplined and efficient try-scoring team was simply unparalleled.

It’s fair to say that he was the reason why the All-Blacks maintained dominance of international test rugby for the better part of a decade, culminating in a triumphant World Cup Final victory over France in 2011.
