Here is my two cents...When I officiate I could care less what is being yelled from the corner. When I am in the corner I lobby hard for calls and for my wrestler. My opinion is that coaches should do that. Watch the NCAA wrestling tournament, watch the NCAA basketball tournament. The officials job is inside the circle unless the coach is using profanity or steps into the wrestling area. If the coach tables an official, the official then should listen and not argue. The less the official says the more likely the coach will be defused. I thank the coach and tell him that I am sticking with my call and I go back to the circle. An official should NEVER take anything said during a match personally. They are paid professionals and should be held to a higher level of conduct than our volunteer coaches. A good officials doesn't listen to the corners, doesn't argue, and leaves his emotions in the car before he walks in.
It sounds like the official got personal and took it personally. He should have never gone to the corner and engaged himself in the discussion.
