Andy Farrell's Rugby World Cup as a coach, have been far from pleasant experiences for the Lancashire man.
As an assistant coach to Joe Schmidt in 2019, he watched as Ireland succumbed to a quarter-final hammering against the All Blacks, in what was Schmidt's last game in charge before he took over the reins.
But it must have felt like paradise compared to the utter disaster of 2015, which saw England dumped out at the group of their home tournament, that will be fondly remembered for their calamitous loss to Wales.
Fast forward eight years and the 2015 coaching ticket are some of the best and most revered in the game.
Head coach Stuart Lancaster is heading to Racing as one of Europe's most sought after coaches, following a hugely successful stint at Leinster; Graham Rowntree has just lead Munster to their first silverware since 2010; Andy Farrell is head coach of arguably the world's best team, with Mike Catt as his trusty attack guru.

Speaking with Balls.ie - in association with Ladbrokes.com - former England out-half turned podcaster, Andy Goode, sat down with us to discuss Ireland, the World Cup, and Andy Farrell.
While Farrell would be the last person to publicly dwell on the disaster of 2015, Goode believes it is a driving force for him, and that the RFU made a huge error in getting rid the entire coaching ticket.
"And you know," said Goode.
"I remember before there was a bit of pressure on him and Mike Catt. When the the change first came, people were getting used to how they wanted to see Ireland attack and the changes that were being made.
"And you're now seeing that come to fruition really, and seeing how clinical they are in attack and how free spirited a lot of the players are within a framework, and massive credit's gotta go to Andy Farrell.
"I'm semi devastated that Ireland's two best coaches or two of the top honchos, Mike Catt and Andy Farrell, who I consider as strong Englishmen, but they're doing a great job for you over in Ireland and rightfully so because the way they got treated by the RFU post 2015 World Cup....
"And let's not forget Eddie Jones didn't want them as part of his coaching team. Well, Eddie's made another mistake there, hasn't he?
"So, they, they're great Blokes. Farrell is a real down to earth guy that wants to do the best by his people, wants to get to know his people and treat them all in ways, that as a coach, you're gonna get the best out of them, and he seems to have done that perfectly at the minute in the sort of framework and culture that he's created.
"And it seems a very happy camp and you can only pat him on the back for that, but he won't want it to be about him."
