Stuart Lancaster faced a monumental challenge as he led England into the 2015 Rugby World Cup on home soil.
However, despite his best efforts, England faltered and was eliminated in the pool stage, marking the first time in the tournament's history that a host nation failed to advance to the knockout stages after defeats to Wales and Australia.
Nevertheless, amidst Lancaster's perceived shortcomings, some of his final debutants for England have risen to the top, aiding Eddie Jones in securing two Six Nations championships.
However, it's worth noting that one player has since retired from the sport, while another has yet to earn another cap for the national team.
Let's take a closer look at the last five debutants under Stuart Lancaster's tenure with England.
1. Sam Burgess
On 10 August, Burgess was named in the England Elite Squad to make his International début against France at Twickenham on 15 August, in a warm-up match for the Rugby World Cup. He started the game which England won 19-14.
Following his appearance where he was sin-binned, World Cup winning English scrum-half Matt Dawson commented: "You can't take him to the World Cup for me. He played 80 mins and credit for that. But the way the game went in the second half there was nothing for him to do. The great thing about Burgess is he doesn't make mistakes with ball in hand. But unfortunately, if you're going to be really picky, positionally he wasn't great. He played like a six rather than a 12. There are things that are instinctively he doesn’t know what to do."
Dawson's comments came before Lancaster named Burgess as one of four centres to represent England in the World Cup. His inclusion and performances at the World Cup were widely scrutinized, and seen by some pundits as partly to blame for England's "humiliating" early pool stage exit from the tournament—the worst result for a sole host nation in the tournament's history.
On 5 November, Burgess made the decision to leave rugby union, opting to return to South Sydney Rabbitohs, signing a three-year contract, approximately worth $1.5m AUD per season.
VERDICT: FAIL
2. Calum Clark
The now 29-year-old flanker made his England debut when he started against France on 15 August 2015 in the build-up to the Rugby World Cup. This would be his only cap to date, however, the flanker has enjoyed considerable success with club side Saracens.
VERDICT: FAIL
3. Henry Slade
Slade also won his first cap against France but has gone onto become a regular of squads since. Lancaster selected the Exeter man for the World Cup with the centre winning his second England cap again against Uruguay in the final pool game, scoring a try.
Slade suffered a nasty broken leg for Exeter Chiefs in the 2015/16 season ruling him out for the six nations under new coach Eddie Jones.
Despite this Slade recovered from his injury and has won 50 caps thus far and will likely be part of Steve Borthwick's 2023 World Cup squad..
VERDICT: SUCCESS
4. Luke Cowan-Dickie
The Exeter hooker also made his full international debut against France in a warm-up match for the 2015 World Cup at Twickenham.
Despite often being in squads, he struggled to win caps due to being behind Jamie George in the pecking order.
However, he's since established himself as a first team player and has won 38 caps.
VERDICT: SUCCESS
5. Jamie George
George was first selected by Lancaster to replace Dylan Hartley in the squad after Hartley was suspended for head-butting George in a Saracens vs Northampton Saints fixture.
He was announced in Stuart Lancaster's 31-man squad for the 2015 Rugby World Cup
just 5 days after making his international debut against France during the World Cup Warm Ups, replacing
Tom Youngs in the 48th minute.
He's since become an England mainstay, winning 69 caps, while also playing six matches on the British & Irish Lions tour including all four tests, one against the Maori All Blacks and three against the All Blacks.
VERDICT: SUCCESS
