If I am a player, I am going to respect my new coach because I was raised by my parents to respect my teachers, coaches, pastors, police, elders, etc. Doing anything else is not an option and it shouldn't be. If kids were taught respect anymore, many of our societal issues would be solved.
Kids don't respect coaches they don't feel respect them.
New coaches tend to be that way at times.
That's a 2 way street.
