Managing the salary cap is absolutely crucial when it comes to achieving success in rugby league.
Clubs can't just stack a team with 20 superstars on huge money and watch the wins pile up.
Coaches are paid big dollars to get the most out of players.
One of the most enjoyable aspects of each season is seeing which players develop into stars.
Today I am here to highlight ten such players who achieved that this year. Moreso those who improved in a big way.
Rookies won't be included for obvious reasons. Mark Nawaqanitawase was not considered for this reason.
These are ranked but honestly the difference between them is so small I'd be happy to swap any position, other than the undisputed number one.
Below are the 10 most improved players from the 2025 season:
Honourable Mentions: Jaxon Purdue, Jack Williams & Simi Sasagi.
8. Deine Mariner

The jump Deine Mariner made this season is hard to describe. He went from a handy centre to a blistering winger, Premiership winner and Samoan must select.
Don't get me wrong, Mariner was no mug heading into the season but his 2024 season was fun. His 2025 season was unforgettable.
I honestly don't think many had him in the international scene heading into the season. It would have been criminal to leave him out of Samoa's first up test against New Zealand.
His Finals series was blistering. Four tries in three games, including a double in the Grand Final. All while averaging 185 run metres in those three games. Phwoar!
