To make a fighter, you got to strip them down to bare wood. You can’t just tell them to forget everything you know, you got to make them forget it in their bones. Make them so tired they only listen to you, only hear your voice, only do what you say and nothing else. Show them how to keep their balance and take it away from the other guy. How to generate momentum off your right toe and how to flex your knees when you fire a jab. How to fight backing up, so that the other guy doesn’t want to come after you. Then you got to show them all over again. Over and over and over, till they think they were born that way.
