Easy knowing you've never coached the game at any age or played at high level ?
You can only get better at a skill by practicing it, it's all well and good doing it in training with no pressure. Try it in a game completely different.
League is for experimenting and trying things.
It's a known fact we're not good in the air catching off puck outs.
Only way we get better is doing it.
Your local club (if you even have one) would tend to do the same in league/challenge games before championship, try a new or different tactic and see if it works.
