The Essence of this thread thus far (although that may not be the original intent of it):
- How can you teach unless you have learnt?
- How can you have learnt if you don't understand and cannot apply?
- How can you apply unless you have 'it'?
- How can you have 'it' unless you have consciously or subconsciously memorized the material under discussion?

Teaching golf is no different from any other teaching profession. You need expertise and to get expertise, you gotta put the time in.
