Better Yet, Let's Agree to Agree ...
 

No, because I think that we agree. You're contacting your assigner and the athletic director. I'm contacting my assigner, who, in turn, will contact the athletic director. Since we're both not doing this for the "regular" fan who gives us grief, but not enough to get ejected from the gymnasium, then we're both holding that coach to a higher standard than the "regular" fan. Voilà. Agreement. Easy peasy lemon squeezy.

I prefer you two disagree. I learn a lot more.:)

not what it sounds like
 

Nope. It was a coach performing exactly like a coach, only well-outside the bench area designated by game management and maybe three rows up.

Fans?....What fans?

They are GM's responsibility. I'm not going to get involved unless they do something to disrupt the game - at that point I'll ask GM to take care of it, and stop the game if necessary while they do so. In my experience, GM is almost always on top of these situations and dealing with it long before we would ever have to get involved.

As to the situation described, if the VC coach is simply in the stands and not on or in the immediate area of the team bench(i.e. row behind if bench is first row of the bleachers), they're a fan and are GM's responsibility. I'm not going to get involved unless they do something to disrupt the game. If the opposing coach has an issue with someone in the stands "coaching", they need to take it up with GM, or through their AD with the state association. Unless/until the state association tells us otherwise, it's not our responsibility. Just my $0.02.......

We have one school in our area where the varsity coach and JV coach sit on the end of the bench during the sophomore game. They often say something to the officials during that game. This is very bush-league. The JV coach got a T for his efforts one game. When I was coaching varsity ball, I had more important things to do than that! I was more concerned about how they were playing the game and how they were being coached.
