Inside the Constraint: Designing Behaviour 3:8
By Coach Barry Jones | IIHF Level 3 High Performance | USA Hockey Level 3 Performance
We Don’t Coach Behaviour, We Design It
Coaches often talk about behaviour.
We want players to support the puck, protect the middle, and make better decisions.
So we tell them. We show them. We run drills to reinforce it.
But behaviour doesn’t come from instruction.
It comes from the environment.
The Shift From Teaching to Designing
Traditional coaching is built on control: demonstrate the skill, repeat the drill, correct the mistakes.
But ice hockey is dynamic, unpredictable, and time-constrained.
Players don’t recall instructions. They respond to what they perceive.
So the question becomes: what does my environment demand?
Constraints Shape Behaviour
Every training environment is made up of constraints: space, time, rules, numbers, and pressure.
These constraints shape what players see, feel, and do.
Change the constraint, and you change the behaviour.
From Drills to Environments
Drills isolate movement and remove context.
Without context, perception disappears. Without perception, decision-making can’t develop.
That’s why players can look great in drills and disconnected in games.
Designing for Perception–Action
If we want behaviour to transfer, we need to connect what the player sees to how they act.
Players must read information, respond in real time, and adapt to changing conditions.
Small Area Games as a Design Tool
Small area games allow coaches to manipulate constraints, increase decision density, and create game-representative situations.
Every repetition becomes perception, action, and adaptation.
Designing With Intent
Good design is intentional.
Ask: what behaviour am I trying to create, what constraint encourages it, and what information must the player read?
If the behaviour isn’t showing up, adjust the environment.
The Coach Becomes a Designer
The coach shifts from running drills to designing environments, shaping behaviour, and guiding attention.
Connecting Back to Identity
Designing behaviour doesn’t just develop players. It develops coaches.
We become better by working in environments that demand better thinking.
Closing Thought
We don’t get the behaviour we ask for. We get the behaviour our environment allows.
You’re not just coaching players. You’re designing the conditions that shape who they become.
What Comes Next
How do we develop coaches to design these environments?
