After last year (2018)'s season, that certain player had better be unbaptized. Otherwise, I don't see how that thing could remain in good standing. First, the coaching--cheating. Do we now allow certain people to cheat (i.e., stealing)? Then there was the racket smashing, followed by a full blown temper tantrum demanding special treatment. This thing broke the rules and threw a tantrum about being punished for it.
I can remember someone in my own former congregation having a fit all night at work because his help called in sick. After trying to steal me from another department where I was needed that night, this thing knocked down displays all night on purpose and left them knocked down. Of course, he got fired. Some time later, I got questioned about what I saw of this incident, and he ended up getting reproved. That, for something far less spectacular than what this tennis cheater did. No way that would have not have resulted in at least a reproof, if the congregation was doing its job.
