As a football coach I always coached the eyes first. Players needed to see before they did anything. This trains the application of the skill. It’s important for a linebacker to know when and where to step before he knows how to take a step. This knowledge cuts down on the total number of steps a player needs to take in order to get to his target. This makes him faster than those that misread the play and have to take corrective steps. I still apply this concept to teams outside of sports. Teaching teammates to see helps them to be proactive instead of reactive. Teammates that do without seeing require too much prompting to prevent them from continuously bumping against a wall like a bad robot vacuum cleaner.
