>>> Is Dr Yeager a proponent of rotational or linear? After watching his DVD seems like his is a hybrid swing. Load linear but swing rotational. Would watching his DVD confuse someone who is trying to develop a rotational swing? <<<
Hi  Kupuna 
Some time ago Dr. Yeager  posted his thoughts on this board and I have read a few of his posts on other boards as well. However, I have not reviewed Dr. Yeager’s DVD nor have I had a chance to read his latest writings on batting principle. Below is a January 2005 post I wrote regarding my thoughts on his theories at that time.
