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.

13. James Segeyaro (2016)
The Papua New Guinea hooker was also on our best signings list, having scored six tries in 10 games to help keep Rhinos in Super League following what was effectively a loan move from Penrith Panthers. But he then refused to return to fulfil a two-year deal, causing Rhinos serious problems on the eve of a new campaign. Photo: Jonathan Gawthorpe
14. Cory Aston (2017)
Leeds paid Sheffield Eagles an undisclosed fee for the young half-back, who signed a two-year contract. He wasn’t given a first team opportunity and left half way through his deal to join Castleford Tigers. Photo: Olly Hassell/SWpix.com
15. Dom Crosby (2018)
An ex-Wigan prop, Crosby secured a three-year deal after seven appearances on loan from Warrington Wolves. Ankle and knee injuries meant he didn’t play in 2019 or the following year and he retired in September, 2020. Photo: Steve Riding
16. Jordan Thompson (2018)
A surprise signing from Leigh ahead of the transfer deadline, Thompson played six games in a brief spell with Rhinos before returning to one of his former clubs, Hull FC. Photo: James Hardisty
17. Tui Lolohea (2019)
Rhinos signed the New Zealand and Tonga pivot from Wests Tigers on a three-year contract, but he rarely found his best form and was swapped for Salford Red Devils’ Rob Lui midway through his debut Super League season, having played 17 games for Leeds. Photo: Bruce Rollinson
18. Wellington Albert (2019-20)
A Papua New Guinea Test front-rower, Albert joined Leeds on trial after leaving Widnes Vikings. He played six times and spent 2020 on loan with Featherstone before joining Keighley Cougars. Photo: Jonathan Gawthorpe
