I'm a table tennis player and I play doubles. We always lose and I thought it's because of our skills but reading your post I realized that we don't talk when we're playing. We just talk to tell at each other that we're gonna lose this and how much we are pissed. Our coach didn't really played as our coach and we are to blame why we lost. That's one of my sad moments in life. Please be a good instructor and don't let your players feel bad about themselves. Your post is nice and thank you, it helped me to reflect to my attitude.
