There is no one way to swing a golf club. Good players are good because they have certain attributes, work hard and maybe they've found an instructor who has helped with improvement. They can be very good golfers even with a swing that is not someone's idea of "text book".My son goes to an instructor similar to what Lane promotes here. He is also an all or nothing type of guy. I listen in and my power/speed and effort have become more effortless in terms of motion. He's helped with grip to use the club as a lever and squaring up the club face efficiently. He has a great way of describing how the arms swing the club. He gets you in the same positions as my instructor but it's cause and effect.
But when I ask about lower body and positions and pressure, he shakes his head "no." I know positions are the effect of a cause but I think you need to see what's happening down there, and whether you are supporting the swing correctly.
I've concluded it's not all or nothing.
I have no doubt Hogan's book has some good stuff in it. But the idea that everything in that book is relevant and accurate is just blind faith. Supporting that faith by making condescending posts towards others who wish to seriously discuss it does nothing but take away what might otherwise be an interesting topic.
