Agree 100%.

How you fix this problem is start with your local club program. Club coaches should set ground rules early on with parents. If we are to coach, let us coach. Parents want to coach, get out on the mat 3-4 times a week, learn moves and the system.

At a HS level, YOU'RE OUT! The HS coach is the coach! No holds barred. Just a simple fact of the sport. Be a supportive parent, not a THORN, in coaches side.
