Nicely done Bob Proctor. In fact, your above post has given me a bit of insight into the coach. Even though I coached for many years, volleyball from youth up through Elite teams, I've never heard the coach vs. ref or ref vs. coach thing put into the manner you did.
I, for one, was always "working" the Up Ref in
VB. Just to let him know I was watching and hoped a few borderline calls would go my way later. (They often did)
Adding, "Coach we're both on the same side." type of comment seems like it might lighten up the sideline from time to time.
Nice post Bob. Thank you.
