Yes he teaches linear movement
--That's kind of an over-simplification, BHD. House teaches that during a certain part of the launch (after the shoulders have opened and the torso is squared up to the plate) pitchers should track directly forward to the target with their eyes, head, and body.
However, to generate most of the power necessary for launch of the ball, House strongly emphasizes 40 - 60 degree hip/shoulder separation and delayed shoulder rotation. This is certainly "rotational mechanics" as I understand it.
In fact, all parts of a pitching delivery are important but they don't all fit into one neat overall box like "linear delivery" or "rotational delivery".
House has dissected and analyzed the motions of 500+ elite pitchers by high speed motion analysis and he seeks to identify the mechanical issues that all (or most) share in common. Another of his goals is to separate the highly conserved mechanical imperatives, which pitchers do need to train and condition for, from personal "signature" issues, which generally should not be "corrected" by coaches.
I have personally seen House's motion analysis database and my son has enjoyed 2 of his own motion analyses over the past 5 years--one at Children's Hospital Kinesiology Lab in San Diego, and the other at House's NPA facility in San Diego. Both of these labs used 8-camera 1000 fps Vicon systems w/ reflective markers. This is the same system that House used to compile his database of elite pitcher motions.
In answer to C's question--during the course of his ~30 year coaching and research career, commenced in 1979 after his MLB playing days were over, House has worked directly with many hundreds of MLB pitchers. He has also worked with many thousands of kids--a few of whom were dedicated, talented, and lucky enough to pitch professionally. More than a few of his 'kid clients' over the years were at least able to enjoy playing at the college level.
Anyone interested in finding a pro pitching coach should definitely develop their own set of litmus tests and a good b.s.-meter for making personal choices. Tom House is clearly not the answer for everyone--but, then, no single coach could ever possibly be 'the answer' for everyone.
