Study: shoulder rotation key to golf drive length

Ever wonder why some golfers consistently pound 300 yard long drives while others can't get close that?

Researchers at Stanford Medical School say they have identified several biomechanical factors that separate the big hitters from the duffers. Scientists analyzed the rotational elements of the swing start to finish. They found that golfers who hit hard have more rotation in their shoulders relative to their hips than the rest of us.
