Their exploits at club level would suggest at least a token cap by now, but not for these unfortunate few. For some it's an inevitability; others a distant pipedream never to be fulfilled...
1. Dan Robson
Robson has set the Premiership alight over the last couple of seasons, but still waiting for an England cap.
The highly-experienced duo of Ben Youngs and Danny Care, who boast 163 caps between them, are seemingly inked in for the RWC and on the occasions that England have had to go to a third scrum-half, they have tended to opt for Richard Wigglesworth or Ben Spencer.
2. Alivereti Raka
Given that “raka” means rugby in Fijian, it was perhaps a foregone conclusion that this dynamic wing would be a success.
He qualified for France on residency grounds in December 2017 and has been tearing up trees in the Top 14 for Clermont. Bernard Laporte, however, has said that only French citizens will be considered for the national team and even given that Raka is married to a French woman, the earliest he can apply for citizenship was last month.
3. Harry Thacker
He's been a revelation since joining Bristol Bears in the summer. Whilst not the finished article by any means, Thacker offers something a little different to the other options Eddie Jones currently has at hooker.
4. Callum Gibbins
Glasgow’s man of the match award seems to have been renamed the “Callum Gibbins Award” since the Kiwi has made the move to the PRO14 leaders. His performances have been standout in a very impressive Glasgow side and there is no doubt that Gregor Townsend will be interested in what he has to offer.
He doesn’t qualify for Scotland through his ancestry, so if he is to win a cap, it appears he will have to wait until 2020 for the opportunity.
5. Jimmy Gopperth
Gopperth has been a model professional in Europe for over eight years now but a sole cap for the Junior All Blacks has prevented him from featuring for England, for whom he would have qualified in 2012, had he felt the desire to.
Unfortunately for Gopperth, he followed hot on the heels of Dan Carter in New Zealand and that was an unenviable shadow for anyone to live in. Gopperth wasn’t the only Kiwi to have had to play second fiddle to one of the greatest players to ever grace the game and just like Nick Evans, that shouldn’t detract from his ability as a player.
