John Danaher

New Zealand-born coach whose systematic approach to submission grappling — particularly the back-attack and leg entanglement systems and the six-hub taxonomy — produced multiple world-level competitors. His six-hub submission taxonomy is the structural foundation for the submission analysis on this site.

is a New Zealand-born submission grappling coach whose theoretical work organised the sport’s submission canon into six interconnected attack hubs and produced the leg lock and back attack systematisation that defined elite no-gi competition through the late 2010s and the 2020s. This site’s hub structure is built directly on Danaher’s six-hub taxonomy. He is cited as a theorist; the work earns the citation, not the lineage.

Multiple ADCC World titles produced across the 2017, 2019, 2022, and 2024 cycles via athletes he directly coached, including Gordon Ryan during the Renzo Gracie / Danaher Death Squad era and into New Wave Jiu-Jitsu. Gordon Ryan’s 2024 ADCC superfight wins are part of this record; the New Wave cohort subsequently competed at CJI 2 (2025) in the team format.

EBI dominance — Danaher-coached athletes won a disproportionate share of EBI events during the format’s peak.

WNO championships — multiple title holders coached or co-coached, including Gordon Ryan’s heavyweight title from inception.

Personal competition — Danaher does not have a competitive record at the elite level. His contribution to the sport is theoretical and pedagogical.

The six submission hubs as the organising spine of the sport. Danaher’s identification of six mechanical families — back attacks, the front headlock / guillotine system, the triangle system, the kimura system, the armbar system, and leg entanglements — and his demonstration that these families are not isolated techniques but interconnected systems with shared entries and counters is the most consequential single contribution to the modern submission canon. This site’s hub architecture is built directly on this framework. Every technique page identifies which hub or hubs it belongs to; that field exists because the hub framework exists.

”Position before submission” as a systematic principle. Danaher’s pedagogical insistence that submission attempts from inferior position are mechanically less reliable than position-first approaches expresses, in plain language, what the invariants framework expresses through connection eliminates space and connection precedes control. Submissions executed from a position where the connection is incomplete are submissions executed against an opponent whose body has the structural space to defend; submissions from positions of complete connection are submissions executed against an opponent who cannot generate independent movement. The principle is the invariant.

INV-01InvariantConnection Eliminates Space and Transfers Weight

"Body-to-body connection at the relevant contact point eliminates structural space and transfers weight, preventing the opponent from generating independent movement."

See full invariant page → INV-07InvariantConnection Is the Prerequisite for All Control

"Establishing connection is the prerequisite for all control."

See full invariant page → The back as the dominant position, with strangle as the dominant finishing system. Danaher’s organisational framework places the back position and the rear strangle at the top of the submission hierarchy on the structural argument that no defensive resource the opponent retains while connected back-to-chest is mechanically sufficient to prevent the strangle, given correct attacker mechanics. This expresses connection eliminates space applied to chest-to-back: the connection eliminates the structural space the opponent would need to face into the attacker, and the strangle becomes a function of attacker patience rather than attacker force.
