My guest today is Mark Broadie, a Golf Statistician and Professor at Columbia Business School. I first found Mark through his book Every Shot Counts, which transformed golf statistics and analytics forever. Marcus worked with many of the world's best golfers, including Francesco Molinari, and Justin Rose, who became the world's number one golfer as a result of their work together. In this episode, we explore the nooks and crannies of golf statistics, we talked about how different kinds of grasses influence players, why approach shots play the biggest role in success for top golfers. We discussed the math behind the drive for show and putt for dough theory, and dive into the reasons why Tiger Woods was so dominant for so many years. Now I live for conversations like this. I love them. And spending an afternoon with Mark talking about strategy, statistics, and golf, the so called greatest game ever played is about as good as it gets for me. And we begin the conversation talking about the strokes gained measurement system which Mark invented, and which dispelled many of the myths and misconceptions about the game of Golf. I hope you enjoy this episode. SUBSCRIBE TO MY “MONDAY MUSINGS” NEWSLETTER TO KEEP UP WITH THE PODCAST.
