Putting is about 40 to 50 percent of the game. It is also the basis for the full swing. The information and skill development you need in putting goes all the way up to your driver. So becoming good at and understanding the basis for putting will be a big factor in what you achieve with your full swing. Remember this is a skill development process one builds on the other. No reason that anyone can become a good putter and perform many of the necessary tasks for the full swing.
