No job in golf has evolved more than the tour caddie. Once just a set of shoulders to carry a bag, caddies have grown to assume different roles for different players. Some have been elevated to where they’re mentioned in the same breath as the guys hitting the shot. Others are just friends or family with no prior caddying experience but serve as a player’s trusted ally and protector. The job has simultaneously grown more complicated thanks to the myriad demands on tour; and easier because of new tools at their disposal. In this episode, Daniel Rapaport talks to caddies and the players they work for about the new responsibilities for caddies, how partnerships are formed, and what happens when those relationships go south.
