Mystery of mastery

My next training, session 2, was called:
“Mystery of Mastery” What makes an excellent coach, excellent”?

What is the difference between a good coach and a excellent coach. 
The trainer was Dr. Stephen Burt.

The topic was very interesting, but i felt it became very theoretical, and it become very “namedropping”…
He talked about Robert Green, Malcom Gladwell and Dreyfus & Dreyfus. And he talked about the four binary qualities: A. Recollections (non-situation or situational B. Recognition (decomposed or holistic) C. Decision (analytical or intuitive)D. Awareness (monitoring or absorbed).

I`d really was hoping for some more practical how to get from a good coach to an excellent coach…
