There is one variable that is very difficult or impossible to model (especially for the grown men crowd). I call it the Clubhouse Coefficient.
The Clubhouse Coefficient is made up of underlying values that make up a atmosphere. This includes each player's approach, how they interact with each other, and certain goals. I have heard many Brewers say in interviews that Murph wants them to be the "best version of themself." There is so much in that statement.
Many on this board complain about someone like Sal Frelick and how he doesn't hit enough home runs. Perhaps that isn't the best version of himself. Does that mean that he shouldn't ascribe to hit more home runs? No. The goal is get the players to find out what they do and do it very, very well. Perfect that portion of "themselves" and then add on additional items like hitting tanks. Imagine how a shorter player would react hearing every day, "you need to hit more home runs" vs. "you hit the ball hard, your homers will come." Or, "let's work on squaring up the ball better" vs. "hit more dongs, dork!"
There are so many things that we middle age dudes cannot understand. Even those that have played at a high level can understand the concept of the Clubhouse Coefficient, but that mysterious value is different for every clubhouse and can change annually, or even during the year. It appears that Anastasio, Arnold and Murphy have kept that number high.
