On the course: Tee shots
The most important way to break 90 consistently is to make good decisions on the course. The average 90-shooter loses more strokes due to poor club and shot selection than to a bad swing or missed shot. I’m convinced of that. I could caddie for the average 25-handicapper and take 10 shots off his or her score instantly–not by overhauling the swing, but by helping with on-course decision-making.
