The biggest fallacies in modern baseball, and there are many others, are pitch counts and launch angles, both driven by the advent of analytics; weird science augmented by those who never put on a glove or held a bat.
IMO, the criticisms of Mendoza and Boone, and I have certainly been right there criticizing Mendoza, in hindsight and with the rooting emotion absent, are largely whistling in the dark because they are not making decisions and moves based on instinct and reactions in the moment but merely by looking at pieces of paper in order to do what they have “been told” by the geeks and their computers in the background.
Complete games and small ball are largely dead because the baseball powers that be decided to kill them.
