The bottom line is, it's all about clubhead speed. There is a direct correlation between clubhead speed and handicap. Lexi swings as fast as Zach Johnson with a driver. She's a freak. Anyone that doesn't understand how these pros are outhitting them, well, their clubhead speed is faster. They're that much better than you. If you think you have a 120 clubhead speed yet shoot 85 or only hit your 8 iron 150, you probably don't really swing that fast. The correlation is very strong. There are exceptions of course but generally speaking, the lower your handicap, the faster your swing, the faster your swing, the lower your handicap.
