As usual, the wily lawyer, Shel, makes perfect sense. Though I must say I was not aware that the esteemed profession of golf swing coach had professional ethics. For Rick Smith to invoke them the way he does is a bit high-handed and pretentious. Unless I'm missing it, there's no such code of ethics embedded in some professional association (ASGSG) other than informal practice.
But then again, just in case, I do make my caddies agree on the first tee that everything to follow over the next few hours is off the record and on a confidential basis.
As for the book, I still think it makes for fascinating reading, reveals lot of detail that we would not otherwise have, and I'm glad Haney decided to write it, despite what will surely be the consequences for his teaching career vis a vis golf pros. Apparently he has decided enough is enough.
