Stoppage vs Transition: Which Rucks Survive 2026?

The Aussie Rules ruck landscape heading into 2026 is the most uncertain it has been in years. Seven new rule changes are targeting dead time and stoppages. For GDS coaches building their ruck line, this is not a cosmetic tweak. It is a structural shift that changes the value equation for every big man in the competition.

The instinctive reaction is simple: fewer stoppages means fewer ruck points. That is plausible, but incomplete. Ruck GDS scoring is not a single stream. It is a portfolio built from two engines. Stoppage scoring covers hitout production, tackles around the ball, contested possessions, and the broader contest ecosystem. Transition scoring covers marks, uncontested disposals, link chains, and getting forward for a goal. The 2026 question is not whether stoppages decrease. It is which rucks have a credible second engine to offset the reduction.

The Stoppage Dependency Split

We built a stoppage dependency proxy for every GDS ruck who played 3+ games in 2025. The proxy weights hitouts, tackles, and ruck contest volume against transition indicators like marks, kicks, and goals. The higher the percentage, the more reliant a ruck is on stoppage situations for their GDS output.

Player	GDS Avg	Hitouts	Marks	Tackles	Goals	Stop %
Jarrod Witts	101.0	43.2	1.6	3.5	0.18	86.1%
Tristan Xerri	115.8	35.0	1.7	6.6	0.20	84.7%
Lloyd Meek	102.5	38.0	2.5	4.1	0.45	81.5%
Reilly O'Brien	101.0	39.7	3.0	3.4	0.13	80.3%
Brodie Grundy	119.0	36.7	3.4	3.9	0.32	76.5%
Tom De Koning	96.8	23.3	3.3	2.3	0.27	68.3%
Rowan Marshall	121.6	27.3	4.5	4.7	0.43	68.0%
Max Gawn	127.4	35.9	5.7	2.2	0.26	67.4%
Luke Jackson	106.6	22.3	3.5	4.0	0.95	66.0%
Tim English	124.4	30.3	6.1	3.3	0.57	65.7%
Darcy Cameron	116.6	28.2	5.2	2.8	0.26	65.5%

The spread is massive. Jarrod Witts (86.1%) and Tristan Xerri (84.7%) sit at one extreme, deriving the overwhelming majority of their GDS output from stoppages. At the other end, Darcy Cameron (65.5%), Tim English (65.7%), and Luke Jackson (66.0%) have meaningful transition scoring to fall back on.

The Xerri Question

Tristan Xerri is the most interesting case study heading into 2026. His 84.7% stoppage dependency is elite, but so is the quality of what he does in those situations. His 6.6 tackles per game led all rucks by a margin and his 85.9 ruck contests per game was the highest in the competition. He averaged 115.8 GDS in 2025, down from 128.3 in 2024.

That 12.5 point drop already happened before any rule changes took effect. His marks fell from 2.9 to 1.7 per game. His transition game was never strong and it got weaker. The question for 2026 is whether his elite tackle volume can absorb the blow from reduced stoppage frequency, or whether he has hit the ceiling of a contest-only profile. The new rules stipulating that umpires will not wait for rucks at centre bounces and that rucks cannot cross the centre line before engaging could directly reduce his secondary stoppage opportunities.

The Transition Ceiling Is Real

The rucks who should weather 2026 best are the ones who already score outside of stoppages. Max Gawn (127.4 GDS avg, 67.4% stoppage) is the safest option. He averaged 5.7 marks, 10.3 kicks, and 20.7 disposals per game in 2025. His transition game is locked in, and he held his GDS average flat year-over-year at 127. He is the definition of a set-and-forget RUC1.

Tim English (124.4 GDS, 65.7% stoppage) is the rising star. He jumped 8.3 GDS points from 2024 to 2025 and led all rucks in marks with 6.1 per game. He also averaged 10.1 kicks and 0.57 goals. His transition engine is the most complete of any ruck in the league, and the 2026 rules should only make that more valuable. English is a legitimate RUC1 candidate who may actually benefit from the rule shift.

Player	2024 GDS	2025 GDS	Change
Max Gawn	127.0	127.4	+0.4
Tim English	116.1	124.4	+8.3
Rowan Marshall	137.0	121.6	-15.4
Tristan Xerri	128.3	115.8	-12.5
Luke Jackson	87.8	106.6	+18.8
Darcy Cameron	110.4	116.6	+6.2
Brodie Grundy	107.4	119.0	+11.6

Luke Jackson (106.6 GDS, 66.0% stoppage) made the biggest year-over-year leap of any ruck, gaining 18.8 GDS points from 2024 to 2025. His 0.95 goals per game is the highest of any ruck in the top 10. The concern with Jackson is ruck sharing with Sean Darcy (72.6 GDS avg, 16 games). If Darcy is fit and gets first crack, Jackson's hitout volume drops. But his forward line impact and transition scoring give him a floor that most rucks cannot match. Watch his preseason role carefully.

The Rucks at Risk

The pure stoppage rucks face the most uncertainty in 2026. Jarrod Witts averaged 43.2 hitouts per game (the most of any ruck) but only 1.6 marks, 5.0 kicks, and 0.18 goals. His 86.1% stoppage dependency is the highest in the league. If stoppages drop by even 10%, Witts has almost nothing in transition to compensate. His 101.0 GDS average is already borderline for the RUC2 cutoff.

Lloyd Meek (102.5 GDS, 81.5% stoppage) and Reilly O'Brien (101.0 GDS, 80.3% stoppage) sit in a similar boat. Both are pure contest rucks who rack up hitouts (38.0 and 39.7 respectively) but generate minimal transition scoring. They are functional RUC2 options right now, but the risk of slipping below that cutoff in a reduced-stoppage environment is real.

The Middle Ground: Marshall, Cameron, Grundy

Rowan Marshall is the cautionary tale. He averaged 137.0 GDS in 2024 (best of any ruck) and dropped 15.4 points to 121.6 in 2025. His marks fell from 5.8 to 4.5 and his disposals from 20.7 to 18.6. His transition engine was real in 2024 but it disappeared in 2025, possibly due to team context and the ruck sharing situation with Tom De Koning at Carlton. Whether Marshall recaptures that 2024 form at St Kilda is the question. The talent is there but the environment changed him once already.

Darcy Cameron (116.6 GDS, 65.5% stoppage) has the profile to benefit. He averaged 5.2 marks and 10.7 kicks per game, giving him the second-best kick volume of any ruck behind Marshall. His 6.2 point GDS improvement from 2024 to 2025 was steady and sustainable. Brodie Grundy (119.0 GDS, 76.5% stoppage) is more stoppage-reliant than Cameron but less extreme than Xerri or Witts. His 11.6 point GDS jump from 2024 to 2025 was impressive, though his 3.4 marks and 7.3 kicks suggest his ceiling is capped without a transition improvement.

GDS Ruck Verdict for 2026

Max Gawn and Tim English are the two safest ruck options. Both have transition engines, both are consistent, and both are least likely to lose GDS output under the new rules. English has the higher ceiling if the rule changes accelerate transition play.

Darcy Cameron and Luke Jackson are the best value or POD plays. Cameron is the steadier option with less variance. Jackson has the higher ceiling but the ruck-sharing question with Darcy adds risk. Both have transition profiles that insulate them from the rule changes.

Tristan Xerri is the riskiest premium ruck. His output is heavily contest-dependent and already declining. He is still capable of big weeks through sheer tackle volume, but the floor has dropped. If you are building a GDS squad for consistency, the data says look elsewhere. If you want volatility and believe his tackle output can absorb the stoppage reduction, he is a calculated gamble.

The bottom line: in 2026, the edge in the GDS ruck line is not predicting whether stoppages go up or down. It is identifying which rucks have a credible second engine in transition. The data tells us English, Gawn, and Cameron are best equipped to absorb the hit. Get their cards before the market catches up.
