The trick is to identify and do those things that the best pitchers in the game all have in common and which are fundamental to maximizing peformance and health. (This, btw, is what the NPA mechanics model is based on.) Going beyond that would mean trying to do things which differ from pitcher to pitcher. There are reasons some things differ from pitcher to pitcher including differing height, weight, wingspan, strength, flexibility, etc.
If a coach made you try to do something just because some other pitcher does it, you'd call that a cookie cutter approach to coaching - right? Don't voluntarily impose a cookie cutter approach on yourself.
