If you're not tracking your improvement, how can you prove it? That's the question we kick around on this edition of the Arccos Golf Podcast. Featuring Cordie Walker, host of "Golf in the Life Of," and "Golf Science Lab," we dive into the minds of golf instructors everywhere by way of a man who knows them intimately. On this edition, we examine just how important proving improvement, building an environment of growth and thinking strategically rather than tactically can be for golf instructors as well as the students they're hoping to help.
