Centre Will Chambers is one of those, and he has been getting plenty of attention in the last fortnight for his on-field sledging.
But according to a report in Sydney Morning Herald, Fitzgibbon will look at form, rather than what's coming out of Chambers mouth to determine whether the veteran will be given a new deal.
It could come more often than not though, given Tracey's ability to cover in the halves, should injury strike there, although the signing of Nicho Hynes and apparent preference of Matt Moylan and Brayden Trindall may also have something to say on that issue.
Chambers was a mid-season signing for the Sharks, returning from a stint in rugby union. The former Melbourne Storm, Queensland State of Origin and Australian Kangaroos representative has played nine games for the men from the Shire, but has struggled for form, scoring just a single try and missing an average of almost five tackles per game.
No other clubs have reportedly expressed interest in the talkative 33-year-old, who had to observe two weeks isolation recently on the back of an accidental biosecurity breach when he landed at Sydney Airport following a stint in Melbourne.
