There are some pretty successful franchises doing a lot of what you just mentioned the reds can’t do. The Dodgers seem to come to mind.
You’re assuming these things have to be mutually exclusive. They aren’t. The Reds aren’t going to be targeting the Lewis Brinson’s of the world and think they are going to turn him into a high walk/low strikeout guy. But when they draft a guy like India who already has a solid approach, the organization will be better off surrounding him with a good player development system that increases his chances of meeting his full potential. How do they ensure the approach carries over and brings success against better and better pitching? Just moving the player along and hoping for the best is no way to do that. That seems like what they have been doing rather unsuccessfully for a while now. Or when you have a draftee with good power and solid bat to ball skills but would benefit from being less aggressive, how do they change that approach early and keep it in check as the player moves up the ladder? Having coaches preaching the same thing at every level will help with that.
Where did I say I place a ton of value on the big league coach? My original comment in which you replied to was about how to implement the philosophy organization wise. But anyhow, incremental improvements at the major league level will pay big dividends. We saw how a poor approach impacted some guys this year.
