After a long time away, I was tuning up my golf swing today at the range. I now see golf thru the lens of a tennis player. There is a slight leak in my tee shots. I wanted to work out the kinks before hitting the links again. I played the ball more off the front foot, and it seemed to do the trick. Driver off the big toe, 3W off the inner heel. I also focused more on hip rotation, and that helped to straight everything out. I also varied how far I stood from the club and the lie angle, and tracked results. Then I realized I was a fool trying to work this out, and next time, just take a lesson and get right to it, and save myself weeks of experimenting. Compare: In golf (and tennis), there are folks with grotesque 3.0 strokes. They've never taken a single lesson, and it shows, just like tennis. Jerky erratic swings. Bunty abbreviated swings. Poor balance. Tight and jerky. Not smooth and fluids. All arms. Swinging hard, yet slower than someone who uses full torso and hip rotation. But, they've spent years perfecting a broken swing and it works. They can reliably hit the ball straight (but not far), but never truly experience the essence of real golf. They might even score well, with the experience in risk management and consistency of 150 yard 5 iron drives. Contrast: At the golf range, there are driving range home run kings who can crush a ball 300 yards but would shoot 120 on the course since they are not real golfers. No sand game, no putting , no chipping, etc. They just practice the biggest shot in golf, the drive. In other words, in golf, the most practiced shot is the drive, and big daddy. Oddly, in tennis, almost no one just sits there practicing the big daddy shot, the big serve. If it was truly parallel, you'd see tons of guys who can serve 100+ mph, yet can't hit a basic groundstroke.
