The job of an NFL head coach allows for plenty of failure. So many things go into the successful execution of a head coach’s role. You must be a motivator. A strategist. A quick thinker. Steady and level-headed with those thoughts. And in the heat of the moment, you need to make the right decision, or those above you will have a much easier decision to make.
It’s easy to become the wrong man for the job. Make a bad call, or waste a timeout at an improper moment. Be a player’s buddy, as opposed to their mentor.
