I've always wondered this. The greatest of all time; one of the greatest drivers of the ball of all time; ended up being the greatest without the benefit of a great short game, so you know his ballstriking was on point. So why not more about his swing? And to be honest, his swing wasn't really all that unusual. Maybe the average golfer doesn't have the strength to make his swing work? If that's the case, why not teach it to strong amateurs? You hear about all kinds of players and their swings; with Jack, all you hear about is 1) Length, 2) Fade, 3) Majors.
How about some insight from the knowledgeable?
