    #202 Predictability is the enemy

    There is a debate that runs through football coaching like a fault line. On one side: all training should be game-based. On the other: players need drills with a lot of repetition. The two camps argue past each other, as if the choice is binary. It isn't. And a volleyball study can help us understand why. Today we walk through a 2023 paper by Paulo Caldeira and colleagues — research that sits close to the intellectual home of this podcast, with Duarte Araújo and Keith Davids among the authors. The setting is volleyball, but the implications belong to anyone who has thought about representativeness in their training. The study took skilled young players and gave both groups the same three attack options against the same three block configurations. Same possibilities, same reps. One difference only: one group knew in advance what was coming, the other had to read and decide in the moment. That single variable, pre-arranged versus emergent decision-making, changed everything. The group that had to read the situation improved substantially more, and kept improving after the study ended. In this episode: what representative decision-making actually means, and why a decision is representative when it is made off the same online information the game provides. What functional movement variability is, and why the best performers don't repeat one perfect technique but find slightly different solutions each time. Also, a football example of how to constrain the option space without losing the decision. Further reading Caldeira, P., Paulo, A., Veloso, A., Infante, J., Davids, K. & Araújo, D. (2023). How functional movement variability facilitates successful skill adaptation during the volleyball attack.

    #196 Game models & Ecological dynamics

    Game models in football are discussed constantly. Most coaches have strong opinions about them, but fewer can describe their own model with depth — or stop to ask where the underlying thinking is actually leading them. In this episode: a new paper by Jones, Kubayi, Stone and Davids that reframes what a Game Model is and what it should do. The core argument is that when a Game Model becomes a script, meaning telling players what to do in advance, it reduces their exposure to the informational complexity of the real game. The player who has learned what to do stands waiting for the right moment to execute a pattern, instead of reading what the game is actually offering. Along the way: affordances and why they appear and disappear in seconds, the difference between skill acquisition and skill adaptation, constraints-led approach, coach feedback reframed as questions that direct attention rather than prescribe solutions, and a new way of visualising the Game Model itself as a continuous infinity loop with a Transition Nexus at its centre. A Sam Allardyce anecdote about the West Ham way, too, which lands well for this context. The thread underneath: if you're coaching from a traditional Game Model, you're trying to build a team that executes your system. If you're coaching from an ecological dynamics perspective, you're trying to build a team that reads the game and adapts. Further reading Jones, G., Kubayi, A., Stone, J.A. & Davids, K. (2026).
