No one really knew what was happening until the Trackman came along. Clarified a lot of myth's. These guys don't have physics degrees. More about feels for the Lee's generation I would think.
A head high bullet like Lee's wasn't going to hold a firm green(even if slow) and Norman's high speed,high launch, high spin shots were, especially when struck with a Tour Edition, which very often hurt Norman when approaching a back pin.
But in defense of Lee, a ball struck off a concrete or cement cartpath does not spin well so perhaps he was on to something for certain angles of attack....Very difficult for me to believe someone who learned golf in El Paso in the early 60's would struggle with firm turf...
As far as PreTrackman, plenty of people knew what was happening, maybe not exactly in some cases,but many poor teachers from that era perpetuated myths that perhap Trackman disproved in their case.
The PGA's ball flight laws were wrong, but MANY teachers knew that they were wrong and understaood then what have become the "modern" ball flight laws. The best players figured it out, even if they stated it differently and many announcers were still calling every shot that went left "over the top"(of the swing plane) for years after the majority of top instructors knew the clubface was the error and in fact that many/most of those pull hooks were hit from UNDER the plane. In 1989 I saw an article by Jim McLean in Golf Illustrated describing this "Swing Left to Swing Right" and it was how I came to be hired by him as I had made a demo tape of a putter being closed and swinging right of target and starting left and my initial conclusion was that at least at lower speeds, the ball flight laws were wrong, and high speed video shown to me by Carl Welty proved to me that the same was true at any speed.(as I already suspected and was already teaching)
Good teachers were also teaching persimmon players to hit slightly up on their drivers,(we always taught players to try to leave the tee in the ground on a driver) and in fact it is the characteristics of modern drivers (low spin,adjustability and shafts) that allow higher speed players to hit slightly down on their drivers for control, at the expense of distance, but they are already long enough.
Do that with a wooden driver and you'd be too short to compete.
