Great topic. I have quite a few thoughts that I have been testing. The org structure above is perfect. There's the technical execution side of the game and a strategic side.
On the technical side, you have to study or have someone show how to perform certain moves. The different pass shots come to mind. Or the rebound goal that AJ is so deadly with. You have certain angles, combinations of buttons presses, etc. It can be hard to see it, reproduce it, and use it if you don't know where to begin. For instance, I'd love to hear AJ break down his step by step rebound shot, or Schmidt or Corbett explain their dekes. There's a technical knowledge there.
On the strategic side, perhaps the most basic question I ask myself and cannot easily answer on offense is, why? Why I am skating or passing it here versus there? Is this way more efficient or productive than doing something else? How should I initiate my offense and why?
I think that the answer maybe lies in how reliant offense in the game is on flow. When I try for a tactic I'm predictable and miss opportunities. As I said recently to Sheehy, the more I play the more convinced I become that great offensei is about time and space. You shouldn't really look for your move. It's initiating offense by making that first defender miss or chase and skating or passing to open ice even if there's no immediate purpose. This creates flow and leads to openings in the defense that your brain will know what to do with when they happen.
