Jordy is completely right... there is more than one way to explain any part of the golf swing. It is all about interpretation.
This is why golf is such a hard game to teach. I found that you can explain one aspect of the swing a certain way to one person and they completetly understand. Yet, I have explained the same thing to another person and they cannot relate to it at all, so then you need to explain it a different way until that person understands what you are trying to explain.
It is only through discussions like these that we all learn from eachother.
We are all here to help each other improve. Please, when someone explains something that does not make sense, reply with courtesy (to the teacher) and ask for further explanation.
Thanks and keep up the good discussions.
