My knowledge of the golf swing is primarily derived from books (and DVDs) written by golf teachers and/or professional golfers. Everything I wrote in my online review of the golf swing, and every opinion I post in this forum, is essentially book-derived. I don't have any original ideas on the golf swing. I simply try to rehash the wisdom of those golf teachers/players as clearly as I possibly can, whenever I write "something" about the golf swing.
