One thing that sticks in my craw every year is seeing fans be so quick to believe that the coaches must know what they are doing when players get benched or cut.
As a teacher and coach, for right or for wrong, whenever a student or player of mine failed, I blamed myself for not finding and pushing the right buttons in order to get the maximum results. for their sake and the sake of the team. I believe there always is a way to encourage and motivate someone and that the greatest challenge of teaching and coaching is finding those ways.
