* Eddie O'Sullivan, having succeeded Warren Gatland as Ireland coach, has helped the men-in-green to 28 wins from 41 since his debut 54-10 defeat of Wales in February 2002, a World Cup quarter-final in 2003, and a Triple Crown - a first in 19 years - in 2004.
Not only that but there have been back-to-back defeats of World champions England in 2004 and 2005 and an autumn Test clean sweep against South Africa, the US Eagles and Argentina last year.
The Springbok success - 17-12 - marked only Ireland's second victory over South Africa in 17 meetings.
Contracted to coach Ireland through to the 2008 Six Nations, O'Sullivan began his coaching career with Blackrock College in Dublin.
He then his reputation with Buccaneers, and with Connacht, before taking to the helm of the Ireland Under-21s.
He subsequently spent two years as technical director and assistant coach of the US Eagles before returning home after the 1999 Rugby World Cup and becoming assistant to Warren Gatland, whom he succeeded.
Now faced with the task of aiding the 2005 Lions' assault on a first Test series win on New Zealand soil since 1974, O'Sullivan will be doubly determined to succeed.
Just as he will when he takes up the Ireland reins again, following the disappointing Six Nations losses to France and Wales, for the autumn Test series ties against New Zealand, Australia and Romania next November.
The Corkman was named as Philips Manager of the Year last year - becoming the first Irish rugby coach since the late Mick Doyle to collect the award.

He was assaulted at Durban's ABSA Stadium shortly after half-time, when a Springbrok fan Pieter Van Zyl ran onto the pitch and tackled McHugh to the ground. Van Zyl was later convicted of assault.
