Want to understand the swaggering art of confidence? Just ask the stoic Koepka 

Imagine if you could attend a sporting lecture on a single subject by a great athlete. What might you pick? Simone Biles on balance or Lionel Messi on technique? Rafael Nadal on the value of a single point or skier Mikaela Shiffrin on control?

Or maybe Brooks Koepka on that elusive ingredient which is trust, faith, training, swagger and certitude blended together. The result is confidence and he wears it like a bespoke suit.
