To me, it makes a whole lot more sense to first figure out what the problem is and then come up with solutions to fix that problem.
Instead of trying to identify the reasons so many young pitchers are injuring their throwing elbows and shoulders, the focus has been on the symptoms of the problem and implementing guesswork measures in that hopes that one might work. Rather, they were taught how not to pitch what some coach suspected they were doing wrong (I say, 'suspected,' because few coaches took the time to learn how to teach pitching).
Twenty or thirty years ago, most pitchers in youth baseball were not being taught how to pitch correctly.
