I don't see a problem with allowing parents in the room during practice as long as they don't become a distraction. I would guess that most clubs would welcome the help of parents who would like to contribute in practices, especially if they had a lot of inexperienced wrestlers in the room. I will say that a parent who comes on the mat and spends their time primarily helping their own child is not what the club needs. If you step on the mat to help out in practice, you should be willing to help out any kid in the room. As a parent/coach for nine years, having my son compete in Junior High and now in his freshman year of High School, these last three years have been my favorite. Being able to step away from the mat and just be dad is great.
