This is dangerous and will lead to elbow and shoulder problems.
Nonsense.
I am the person who figured out this pattern, and I can tell you that trying to start the throw with the forearm horizontal is guaranteed to cause elbow and shoulder problems while the Inverted W or Inverted L only might cause elbow and shoulder problems.
That's fine, but getting the forearm vertical won't guarantee a pause (unless you teach that, which I don't).
I knew you would be chiming in Chris. IMO what you prescribe is at the root of a lot of arm problems. I tried your approach for years and my daughter always had a sore arm. Too much slack in the system. I also do not teach the upside "W" position that some experts now believe causes arm injuries. As I recall, Strasburg is an upside down "W" pitcher, whereas Maddux did what Hodge and I teach. You may want to do some more research on what Hodge teaches.
Here is a clip of Maddux. His throw is triggered prior to foot plant, just like 99.9% of the guys reading this thread do. It's natural. The likely reason why Maddux never had arm problems is because of his arm position during the back swing, which remains horizontal to the ground.
