A bumper crop of newcomers burst onto the NRL scene in 2025, with Roosters centre Robert Toia dux of the class to take Dally M Rookie of the Year honours ahead of Warriors game-breaker Leka Halasima, gifted Eels fullback Isaiah Iongi and Raiders rake Owen Pattie.
But the spotlight will intensify on the breakout stars this season as they look to avoid the dreaded ‘second-year syndrome’.
The modern era is littered with brilliant tyros who struggled to back up their rookie-season heroics. These are the most noteworthy cases.
Jim Leis
The first Dally M Rookie of the Year recipient in 1980, Wests lock Leis was also named Lock of the Year, toured New Zealand with the Australian side and represented NSW in the inaugural State of Origin match.
The Tamworth product could not replicate those feats in ’81, however, turning out in just 14 games for Roy Masters’ Magpies. Leis’ premiership career subsequently fizzled out with underwhelming stints at Canterbury and Cronulla.
David Liddiard
Indigenous winger David Liddiard was a standout for Dally M Rookie honours in 1983, playing all 27 of Parramatta’s matches and scoring 12 tries on the way to a debut-season premiership.
But he backed up with just 11 starts in 1984 and was shunted to the bench for the Eels’ finals campaign. Subsequent stints with Penrith, Parramatta again, and Manly paled in comparison to his rookie year heroics, taking a decade to muster 135 first-grade games.
Steve Linnane
Diminutive Dubbo junior Linnane enjoyed a spectacular introduction to the big time as St George’s halves linchpin in 1985, leading the premiership with 17 tries as the Dragons clinched the minor premiership before going down to Canterbury by a point in the grand final.
The Saints dropped to seventh the following season and Linnane managed just two touchdowns in a frustrating sophomore season, while a 20-week suspension for gouging late in ’87 stymied the tough playmaker’s progress.
Paul Sironen
Balmain second-rower Sironen’s rampaging runs and crunching defence garnered Dally M Rookie of the Year honours and a Kangaroo Tour berth in 1986.
But while Kangaroo teammates Les Davidson and Phil Daley secured debuts in the NSW pack in ’87, Sironen was overlooked by Origin selectors thanks to patchy form at club level. ‘Sirro’ soon became a representative staple after surging into Australia’s 1988 World Cup side.
Jim Serdaris
Just 17 when he debuted in first grade, nuggetty rake Serdaris made such an impact for 1989 minor premiers South Sydney that captain and NSW Origin hooker Mario Fenech was shunted to prop, while he edged another schoolboy sensation, Balmain’s Tim Brasher, for the Dally M Rookie nod.
His follow-up campaign mirrored that of the club’s, demoted to the bench and making just 14 appearances as the Rabbitohs collected the wooden spoon. A season at Canterbury in 1993 rejuvenated the dynamic No.9 and he toured with the ’94 Kangaroos from Western Suburbs.
Matthew Rodwell
Classy No.7 Rodwell steered Newcastle to its maiden finals series in 1992, forming a superb halves combination with veteran Michael Hagan, and winning the Dally M Rookie of the Year award and the inaugural Norwich Rising Star award in a canter.
Fresh-faced and well-spoken, Rodwell was a marketer’s dream but form deserted him in 1993 and he was overshadowed by newcomer Matthew Johns, whose younger brother Andrew forced him out of the Knights’ line-up in ’94.
Rodwell resurrected his career with solid stints for Western Reds, St George and Penrith, finishing with 178 first-grade appearances.
Jack Elsegood
Flashy 19-year-old winger Elsegood was pencilled in as a 1994 Kangaroo Tour certainty after an incredible ’93 rookie year for Manly that included 12 blistering tries.
But the flyer became the all-time poster child for second-year syndrome after an early-season shoulder injury and a string of head-high tackles shattered his confidence.
Coach Bob Fulton eventually dropped Elsegood late in the season while the likes of Wendell Sailor came from the clouds to nab an Australian jumper.
Although he was left out of the Sea Eagles’ 1995-96 grand final sides, Elsegood finished with 60 tries from 149 first-grade games following an impressive stint with the Roosters.
Luke Burt
After debuting in front of more than 100,000 fans at Stadium Australia’s grand opening in 1999, Burt racked up 24 rookie-season appearances for NRL heavyweight Parramatta.
The goalkicking winger started just 10 games in 2000, though, relegated to the bench – or left out altogether – for much of the year by Brian Smith as the likes of Pat Richards and Eric Grothe Jr emerged.
But Burt’s consistency eventually shone through, playing 264 games for the Eels and tallying 1,793 points, including a club record 124 tries.
Tasesa Lavea
Lavea, the 2000 Dally M Rookie of the Year, debuted for New Zealand at the end of his first NRL season and was selected at five-eighth against France mid-season in 2001, but his sophomore year form for Melbourne lacked the same spark.
Lavea switched to rugby union following a dismal stint with the Northern Eagles in 2002.
Tim Smith
‘The next Peter Sterling’ tag claimed yet another victim in 2006 as Parramatta’s boom No.7 Tim Smith failed to back up his sizzling debut campaign.
A runaway Dally M Rookie of the Year winner after guiding the Eels to the ’05 minor premiership and racking up an astonishing 40 try assists, Smith was a shadow of the confident halfback wunderkind the following season and missed most of the club’s late rally to claim a finals spot.
The gifted ball-player led a troubled subsequent rugby league existence, leaving the Eels early in 2008 after revealing he was suffering from bipolar disorder, while stays at Cronulla, Wakefield Trinity and Salford City were punctuated by off-field indiscretions.
David Williams
Manly’s David ‘Wolfman’ Williams became a cult figure, grand final winner and Australian Test wing in his 2008 rookie season. But he endured a woeful Origin debut in 2009 and was less effective at club level before injured wiped up his 2010 campaign.
Williams’ career spiked with a 20-try season in 2013 as Manly made another grand final but he was relegated to NSW Cup two years later and retired with just 103 NRL appearances to his name.
Daniel Mortimer
Unheralded 20-year-old half Mortimer was a key element of Parramatta’s extraordinary charge to the 2009 grand final, scoring 10 tries in 18 games for the Jarryd Hayne-inspired side.
He endured an indifferent season for the hot-and-cold Eels in 2010, however, targeted by opposing teams and struggling with the playmaking duties. Mortimer was dumped to NSW Cup during 2011 but won a premiership with the Roosters two years later after adapting to a utility role.
Shaun Johnson
Quicksilver halfback Johnson lit up the NRL in 2011 with his unique blend of speed, footwork and ball-playing wizardry, guiding the Warriors to an unlikely grand final appearance.
It may be a stretch to say he suffered from second-year syndrome given he was the ailing team’s equal-top tryscorer (12) and led the team for try assists (17), he was one of many players to suffer a form slump during the Warriors’ lengthy late-season losing streak and was dropped for the final round.
Johnson was one of the game’s most irresistible, mercurial and oft-maligned talents in a highlight-laden 14-season career.
Jamayne Isaako
Canterbury (NZ) product Isaako scored 11 tries and finished second in the NRL with 239 points in a superb 2018 Dally M Rookie of the Year season for Brisbane, culminating in a Kiwis call-up.
But Isaako crossed just four times in 2019 and his career stagnated for several seasons, prompting an underwhelming mid-season switch to the Titans in 2022.
He regained his best with the fledgling Dolphins in 2023, however, becoming the first player to top the NRL’s tryscoring and pointscoring charts in the same season since 1990.
Jeremiah Nanai
An incredible 17-try season in the second-row for the high-flying Cowboys in 2022 netted Nanai the Dally M Rookie of the Year award and a Kangaroos World Cup call-up, having debuted for Queensland earlier in the year.
But suspension and injuries stymied his progress in 2023, restricting Nanai to six tries from 13 games. While perhaps not hitting his rookie-year heights again, the aerial threat has been a regular in the Queensland and Samoa line-ups – and on the Cowboys’ tryscoring sheets – in subsequent seasons.
