O’Brien adapts and survives
A colossus in defence and a wrecking ball in attack for Ireland in their famous World Cup win over the Wallabies at Eden Park, O’Brien was not even playing in his favourite position, preferring the ball-carrying blindside flanker’s role or number eight to the shovelling and scavenging work required of a seven.
Yet he managed to produce a multi-faceted display that highlighted all that was good in any back-row position, perfectly in tandem with Stephen Ferris at six and Jamie Heaslip at eight.
