(1) PERCEPTION / ACTION COUPLING
Its about performing a skill relative to perception on the floor. This principle can not be forgotten.
Action: Guide players towards what they should perceive on the floor as a cue to perform the skill.
(2) EVERY PLAYER IS UNIQUE
Each "perception" presents a problem to be solved. Each player will have his own unique way to solve that problem.
Action: Guide players towards two outcomes. 1. That the skill be simple in nature, so that the player can stay balanced and keep his eyes up. 2, That the skill be high percentage. The player projects to be able to perform this skill at a high percentage in the near future
(3) TOOLS OVER RULES
The analogy is a backpacking trip. "Lets say you and I were going on a backpacking trip and you needed me to pack your bag. How would you want me to pack it? Overpacked? Underpacked? Full of my things?
Probably not.
What you would want is a bag of versatile tools that could be used for any situation. Not so much that it weighs you down, and not so little that you don't have the answers. But a simple backpack full of versatile options.
And than, I as the coach, need to let you use your own bag!
Action: Avoid overly rigid, "this, than, that" formats. While it will be a small piece in the teaching progression, it is not the endgame. Build general tools in players. Simple fundamentals that can be stretched and adapted into various game situations.
Once a player understands the core fundamental. Challenge it with as much variability as can be created.
