The understanding of pitching mechanics is probably in the dark ages. I bet that 20 years from now, there will be an accepted "best method" that will have been scientifically developed to deliver the best pitches with the least chance for injury. Then, this will be taught to every pitcher from the smallest little leagues on up.
Frankly I'm not sure this homogenization of the game is a good thing, in fact I'm pretty sure it isn't.
