Baseball is full of what I call pitching destructors, instead of instructors. They do more to break the pitcher down than to build him up. The problem is they see the pitcher as something other than an athlete. It takes an elite athlete to throw the ball 90+mph on a consistent basis. Yes, genetics has a lot to do with it and someone who is long, lanky and quick will have an easier time throwing 90+mph than a person who is short, stocky and slow, but genetics can be enhanced and this is the job of an instructor.
Where most pitching mechanics go wrong is when the delivery changes from a ballistic movement to a choreographed movement. Pitching is not like dancing. It is more like a broad jumping. If a pitching instructor doesn’t keep this in mind then everything can go wrong. It is very common for hard throwing high school pitchers to go to college and loss velocity instead of gain velocity. This should only happen if an injury has occurred. This should never happen unless you have a destructor for a pitching coach.
Types of coaching styles that take away from the ballistics of pitching is coaching the pitcher to control the arm more during the delivery. Most pitching coaches take this approach. Another destructive pitching approach is when a pitching coach focuses on one exercise or drill as the “be all, end all” to training the complete pitcher. Explosive pitching mechanics use the stride phase to generate power. This would mean the starting position of the lower kinetic chain is what must be coached first before the throwing phase which happens at the very end of the delivery. Training the complete pitcher involves a fusion of exercises, drills and lifts. The ultimate approach to pitching is called 3X Pitching.
