AS is 34. Age may well catch up with him and he may well experience back issues a few years down the road.
And - again, it’s all about translating it all to the golf course, in a competitive, pressure filled environment. As an ex-golf bum, I’ve played w/ a lot of great players, including Jack (for 9 holes).
A good friend of mine was Jeff Gallagher. I was in awe of his talents. He literally wanted to know the course record every time he stepped on the first tee. I would have made Rory’s Dad’s bet with Jeff - that’s how sure I was of him.
Though his brother and sister had success, it just never happened for Jeff. He and others I know on the fringe show you how fine the line actually is.
