Mr. McLean is no doubt an expert in golf -- I have no doubt about that. I have seen serveral of his videos and have gained from them. This book, however, could have been helped immensly by a strong editorial hand. Mr. McLean waffles on and on about fragmentary parts of the swing, interspersing it pointless stories and dropped names. Only one point comes through clearly: the power in a swing is generated by the differential between the hip and shoulder turn. I am sure that if I re-read the book more points would come to light, but it is far too tiresome.
