In a salary cap sport, not every member of a squad can be a superstar.
Sometimes young players destined for big things don't make the grade at the first attempt, ones who arrive with a huge reputation fail to impress or occasionally things just don't work out.
Here's 17 players - some of them legends at other clubs - who had a relatively brief stint at Rhinos, with varying degrees of success.
How many do you remember?
13. Ben Cross (2011)
Signed from Newcastle Knights, the Aussie prop was limited to one start and nine games off the bench before joining Wigan. He is now coach of Queensland Cup side Ipswich Jets. Photo: Steve Riding
