As I indicated, players and coaches are now reviewing videos of themselves and other great hitters, as well as the interent and speaking with others who have reviewed video and the interent, and are now understanding the swing.

The transformation occurred because most players now understand how to execute swing mechanics because players and coaches are now understanding rotational swing mechanics. However, as I indicated, for decades and decades, the good hitters to which you referred taught weak linear mechanics. While I could probably identify 5-10 hitters today who are primarily linear, I could have named 50-100 in 1980s and 25-50 in the 1990s. This again is no coincidence. Linear mechanics are not effective and the understanding of this fact has drastically changed over the last 10 years. Prior to the 1990s, many good hitters and coaches advocated that you had to be born with good swing mechanics because they did not understand how to teach good batting mechanics. Whether you want to believe that the change occurred because the good hitters/coaches suddenly figured it out in the 1990s or for some other reason is up to you, but I believe that the change began with individuals who devoted time and effort to understanding the swing with the assistance of video analysis, and then applying that understanding on the ball fields. And I am certainly not trying to defend Jack Mankin - his theories stand on their own - even though many like to diminish his credibility by suggesting that he has not played professional ball. In fact, I was responding to your post to BHL, suggesting that we should not give any credance to his thoughts because he is a paper nerd. I do not agree with BHL's new theory, but I think that we should find stronger arguments than claiming that non-pro players who are trying to develop an idea are nerds.

After spending many hours looking at video of today's stars, only Ichiro has what most of us would term "linear" mechanics, although I would use the term "poor mechanics". He clearly has an unorthodox swing that has lunging, lateral head movement, etc. all in one.

As for past stars, very few had "linear" mechanics as defined by Jack. Pete Rose, for example, had a beautiful circular hand path and excellent "bottom hand torque", although he had no "top hand torque". Ty Cobb also had a "rotational" swing based on viewing the few swings of his known to exist. I know, it sounds sacriligeous, but the two greatest singles hitters of all time both had "rotational" swings as defined by Jack.
