There are a lot of different approaches to coaching. If I am being honest, my favourite coach I ever had was the most difficult I ever played for. He would yell at you, he would get up into your face, he would grab you by the facemask, the pads.
At the same time, he would know your interests and make conversation with you, he loved and cared about you.
For example, my Jr year of HS, I played RB and I fumbled the ball on back to back plays (both were exchange issues) he grabbed me by my facemask and told me to get it right or leave. I was a little hurt at the time, but I shook it off and finished practice. That same day, the yankees (my team and his team) were playing the a playoff after practice, and he saw me running to the bus stop. He picked me up and drove me home so I could get home to watch the game sooner and we bonded by listening to the game in the car.
I love him to death and I feel incredibly privileged to have played in his program. If he ever was called out/sued for his coaching tactics, I would go to bat for him. I would go to the court proceedings to show support. People are getting too soft
