Eddie O'Sullivan

In May 2014 O'Sullivan was confirmed as head coach of Biarritz Olympique. Relegated from the Top 14 following the 2013-14 season, Biarritz played in the Pro D2 league in 2014-15. O'Sullivan left Biarritz Olympique in October 2015.

In 2009 the position of Head Coach to the USA Eagles Men's team came open when Scott Johnson announced he would leave the team at the end of the 2008–09 season to move to Ospreys of the Celtic League. O'Sullivan's agent reported on 16 February that O'Sullivan had signed a deal that would see him coach the United States through the 2011 World Cup. His hiring was officially announced on 4 March. O'Sullivan coached the USA Eagles from 2009 up until the end of the 2011 Rugby World Cup. It was O'Sullivan's 5th appearance at a Rugby World Cup in a coaching capacity (RWC 1991 S&C Coach Ireland, RWC 1999 Assistant Coach USA, 2003 Head Coach Ireland, 2007 Head Coach Ireland, 2011 Head Coach USA)

On 19 March 2008, O'Sullivan resigned from his job after a disappointing 6 Nations campaign. O'Sullivan finished with an overall success rate of 64% during his tenure with Ireland. During his time Ireland reached 3rd in the World Rugby ranking on 2 occasions in 2003 and 2006.

In August 2007, O'Sullivan's contract with the IRFU was extended for a further four years, which meant that he was contracted to be in charge of the Irish Rugby Team until 2012. Part of the terms of the contract allowed him to leave the position temporarily to coach the 2009 Lions squad, were he to be offered that role. Soon, however, he was the subject of press criticism after a run of poor results. Ireland turned in poor performances in the opening matches of the World Cup against the lower rated Georgia and Namibia. They had previously also struggled in pre-tournament games against Italy and Scotland. Criticisms included a failure to inspire passion in the team and a lack of depth in the squad, which has been said to have caused complacency in the first team players. Many began to see the signing of his contract as a premature move. Rumours have abounded of conflict in the Irish during the tournament, and even that Geordan Murphy might leave the squad as a result of being dropped from the bench for the French game. The poor performances continued with the failure of Ireland, for the second time in its history, to qualify for the quarter-final stages of the World Cup, finishing third in its Group with two wins and two losses. After an extensive post Rugby World Cup review it was established that, despite rumours during the tournament, there was no discord among the playing squad. The failure to perform was identified as an over emphasis on strength and conditioning prior to the tournament along with only 2 pre-tournament warm-up games, leaving the squad short of match preparation.

Ireland again missed out in the 2004 Six Nations Championship, losing the Grand Slam to France this time, but went on to win Ireland's first Triple Crown in 19 years. While transitioning the team during the 2005, O'Sullivan's side finished in third place with defeats by France and Wales. In 2006 defeat to France cost Ireland the Championship. In 2007 again Ireland lost the championship to France on points difference. On the final day of the tournament despite defeating Italy heavily in Rome (51-24), France defeated Scotland with a controversial try in the final minute of the game to again deny Ireland a 6 Nations Championship. The fact that the French played later in the day than Ireland gave them an advantage of knowing exactly what score they needed to secure the Championship. This fuelled the discussion about games not kicking off at the same time on the final day of the tournament.

During his tenure as Head Coach to Ireland O'Sullivan won 3 Triple Crowns, in 2004, 2006 and 2007. Ireland also defeated Australia twice (2002 & 2006) and South Africa twice (2004 & 2006). Ireland defeated England in the Six Nations Championship over four consecutive years (2004 - 2007) including a record victory (43-13) at the iconic Croke Park Stadium in 2007. O'Sullivan also coached the Barbarians R.F.C. to victory over the 2007 World Cup Champions South Africa in November 2007.

In his first year Ireland finished third-place in the 2002 Six Nations Championship. O'Sullivan's Ireland went on to achieve second place in 2003, only losing the Grand Slam in the final match against England. At the 2003 Rugby World Cup his team lost to France in the quarter-finals.

After failing to secure a high-profile coaching position in Ireland, O'Sullivan moved to America to coach the US Eagles where he worked as Forwards Coach at the 1999 Rugby World Cup He also worked as Technical Director to USA Rugby between 1997 and 1999. As Technical Director he developed and delivered the USA Rugby Coach Education Programme, which certifier coaches at Foundation, Level I, Level II and Level III. He was then appointed as the assistant coach of the Irish national side in 1999 as the Backs Coach. During his time as Assistant Coach he was credited with advancing Irish back play considerably while working with players such as Brian O'Driscoll, Ronan O'Gara, Peter Stringer, Rob Henderson, Shane Horgan and Denis Hickie. In 2001 he was appointed Head Coach following the controversial departure of Warren Gatland.

After coaching the Irish Under-21 team to their first ever Triple Crown in 1996, O’Sullivan joined USA Rugby as Assistant Coach to the Eagles (Forwards Coach) and Assistant National Technical Director to USA Rugby. In 1998, he took over as National Technical Director while still retaining his position as Assistant Coach on the Eagles coaching staff. He worked with the Eagles at the 1999 Rugby World Cup before returning to Ireland as Assistant Coach to the Irish Rugby Team (Backs Coach).
