Today I still don't make much money from working with Tour players. My payment arrangements range from a small percentage with certain players to a piecemeal deal as to when I see them. With Jim Carter it's more of a piecemeal arrangement. Besides, these players often become good friends of mine. Today, there are a number of teachers working with players.
Some players have teachers they've worked with since junior golf and college.
In contrast, look at the Senior Tour. There are few if any swing coaches or gurus who follow the Tour. That's because those players largely grew up taking care of their swings by themselves. They figured it out on their own. Sure, Nicklaus used to work with Jack Grout and Bobby Jones before that used to work with Stewart Maiden in Atlanta.
