The NRL salary cap could reach $16 million by 2028, although negotiations with the Rugby League Players' Association have not begun.
That possible increase may give clubs greater flexibility when the November 1 contract market opens.
Latrell Mitchell, contracted to South Sydney through 2027, will be eligible to negotiate with rivals from that date.
The Rabbitohs are entering that period after Newcastle ended their finals hopes, creating major roster decisions.
News Corp reports that South Sydney will wait on Mitchell while prioritising second-rower Tallis Duncan's future.
Duncan is among several players who could attract rival interest, alongside Campbell Graham, David Fifita, Brandon Smith, Jayden Sullivan and Jack Wighton.
Mitchell's value will be closely examined because of his recent availability record.
The 29-year-old played 12 matches in 2026 and only 34 across the past three seasons.
His ability remains unquestioned when fit, with the State of Origin centre still one of the competition's most damaging players.
However, South Sydney and potential suitors must weigh that impact against his injury history.
Without a new Redfern deal, Mitchell would enter a strong centre market featuring Bradman Best, Herbie Farnworth and Jack Bostock.
Consequently, the Rabbitohs' decision involves more than simply judging whether Mitchell remains among their best players.
