These are not the worst players to feature for the club, some of them had glittering careers elsewhere and one even features on both lists.
But - for reasons including injuries, homesickness, bad luck or in some cases because they weren’t very good - they didn’t make the impact they or the club would have wanted in blue and amber.

19. Rhys Evans (2020)
The experienced Welsh international joined Leeds from Bradford Bulls ahead of the Covid-hit 2020 season as cover for the outside-backs. He scored one try in five games before returning to his previous club. Photo: Bruce Rollinson
20. Joe Greenwood (2020)
The forward joined Leeds on a two-month loan from Wigan Warriors and was due to make his debut away to Catalans Dragons, but the game was cancelled after he developed possible coronavirus symptoms. That was a false alarm, but his deal expired during lockdown without him having played a game. Photo: Bruce Rollinson
21. Kyle Eastmond (2021)
The former St Helens half-back - a dual-code international - was a high-profile recruit by Rhinos from Leicester Rugby Union Club. He signed a two-year deal, but hung up his boots after just two months and a couple of appearances, admitting he no longer had the passion to play at the elite level. Photo: Bruce Rollinson
