In this regard, I always love reading Vern’s stuff. You take the demands of the event, know the technical model you are trying to achieve, and work from there. Cues are simply a means to an end. Some athletes you can tell them what to do, some need to be tricked.
I do agree that teaching 5th graders or below, not even necessarily PE, will force explanation at its finest because the obvious to us becomes a complication to them.
On sight advice is always tricky to pass along because it depends on the set up the entire program from beginning, middle and end. With most events, I tend to work backwards so the athlete always knows where they want to get regardless of how the process is going to happen. It is the same with planning a periodization model, you have to know where you are going then work towards the start.
