Rory McIlroy is a professional golfer on the PGA tour and a future member of the Hall of Fame. He has one of the purest swings in golf and is known to drive the golf ball a mile. His golf game has the entire package and is validated by his 20 victories on the PGA tour. In fact, McIlroy is knocking on the door of the career grand slam, where only 5 golfers have won all 4 majors on the tour. Rory’s skill and talent are undeniable but we know very well that the success of any golfer is due in part to the person that wears multiple hats on the course – from psychologist to risk assessment analyst – the caddie.
