The Constraints Collective

This month's guest podcast: Ian Renshaw is joined by Jay Carter, Golf New Zealand's National Team Coach and host of the *Talking Performance* podcast (197 episodes and counting), for a conversation built around a clip Jay sent after listening to TCC's Güllich episode. Jay's own 2024 interview with Ryan Fox — republished this August after Fox won The Open Championship at Royal Birkdale — became the case study: a New Zealand sporting-royalty kid (father Grant Fox, All Black goal-kicker; grandfather Merv Wallace, Black Cap) who made First XI cricket and First XV rugby at King's College alongside Tim Southee, and didn't get serious about golf until university.

The conversation moves through why "smash it" beat "be accurate" in Fox's early sporting intentions, the golf course used as an after-school playground before the game's popularity boom priced that out, why practicing to "feel better" isn't the same as practicing to get better, the transactional trap in paid coaching (and what it would take to actually get fired for being honest), boredom as a genuinely useful training constraint, and a caddying story from the Kazuma Kobori bunker at Royal Queensland that turns into a case study in broadening a player's affordances rather than narrowing them to "the right shot."

This month's theory paper review: Ian and Keith dig into Woods, Richard, Martin & Cairney (2026), "Loosening Tightened Logics: A Comment on the Role of Affordances," published in New Ideas in Psychology, 83, 101289 — a paper that never mentions sport, and covers park benches, glass building facades, and a Brisbane street corner that turned itself into a shared garden without anyone designing it that way.
The idea at the centre of it: every training environment sits somewhere on a tight–loose dial. Tight space prescribes its own use — a cone drill, a single technical model, a serve that must land in a taped box. Loose space supports activity that unfolds in ways nobody specified in advance — an adaptable small-sided game with no one correct solution. Most environments drift tight without anyone deciding it should happen, and the paper argues almost nobody notices until it's named. Ian and Keith trace the theory back to Gibson's concept of affordance, work through the paper's case study of a university building facade that became a free dance studio purely because of what its surfaces afforded, and land on the practical takeaway: a coach's job isn't to fill the room, it's to decide, session by session, how much of it to leave open.

This month's guest podcast: Ian Renshaw and Keith Davids are joined by Craig Harrison, who spent almost ten years running the long-term athlete development programme at AUT Millennium in Auckland and has just written a book, *Coach by Design*, about what he learned. Craig's central distinction splits environment design into two separate levers — structure (what the space lets a learner choose and perceive) and control (the force a coach applies to direct decisions on top of that) — rather than a single dial between drilled and unstructured training.

The conversation moves through the skate park as the clearest picture of designing for "everyday risk," the Maori concept of Tuakana Taina and cross-age mentoring, the "coffee club" Craig ran to help parents make sense of a more exploratory-looking programme, and the "Bambi effect" — the temporary loss of coordination that comes with a fast growth spurt, and why it calls for more structure and control rather than less. Late in the conversation, Ian connects Craig's framework directly to this month's theory paper review of Woods, Richard, Martin & Cairney (2026) on tightened and loosened space — the same underlying question, worked at two very different scales.

This month, Ian Renshaw and Keith Davids work through a run of stories that all land on the same idea: the environment you train in writes itself into your technique, whether anyone designs it that way or not. Ian opens with a story from one of the Collective's members in India: a Mumbai coach, Amladi, who could sort a cricket trial into two groups just by their batting stance, correctly picking out which players had grown up on underarm gully cricket in the lanes of Dadar, Matunga and Shivaji Park, and which had grown up playing the overarm version around South Mumbai and the suburbs. Keith connects it to skill adaptation and the idea of learning to address the performance environment, not just coordinate an action within it.

From there the conversation moves through Pete Arnott's work with Scottish golfers, whose short, tight links courses have produced accurate but short hitters, and how he manipulates practice environments to prepare players for different tour conditions. Keith shares a video sent by a colleague in Buenos Aires of Estudiantes de la Plata's La Osha training ground, deliberately left to the weather since the club's 1970s championship years, where academy players learn to control the ball on a surface that looks nothing like a manicured pitch. Ian follows with the Indian hockey team that lost its edge in stick skill once the game moved from rough turf to astroturf, Pele's adjustment to boots after growing up playing barefoot, and two stories from the London 2012 Olympics, a long jumper who had actually practised jumping into the wind, and a pole vaulter who trained indoors and got caught out by it. Keith closes on why "closed" and "open" skill is a less accurate way to describe this than tasks with more or less information, and more or less stability.
