A major key in life is knowing when to stay in your lane.
For instance, football coaches have a wealth of knowledge. How to shade a three-technique in order to properly disrupt split-flow blocking. How a quarterback should tilt his shoulders after a play-fake in order to manipulate the deep safety to open up a post-dig combo. The width a receiver should keep his feet at in order to properly win inside of press coverage for a slant route.
Coaches spend years studying — both in the classroom and in practical situations — to understand these things.
