It's like safety, productivity, and quality in industry: figure out what works best and create a culture in which things are done this best way virtually every single time.
One big Phillies problem has been lack of consistently. They've been all over the map on what they want, changing approach. We could not draft a H.S. position player or sign a 16-year old international player and have him travel through our development process with a consistent focus upon improving his strengths and minimizing his weaknesses which our scouts saw when we drafted him.
We draft for speed and athleticism, then we draft for raw batting practice power, then we draft for sweet high contact rate swings to reduce Ks, then we seek loft, we focus on defense then are willing to ignore it in our top $ signings. This is a result of starting late on analytics and then chasing one fad after another. Since we are slow to shed the old staff when the approach changes, we have little consistency within the organization. We loved the Randolph and Moniak swings as much on draft day as strongly as we later were determined to alter them. Our young players have to be confused.
