I was noticing this today. I've noticed it before in international basketball but it becomes more pronounced when you're watching international players competing against college basketball players. The German players were yipping and mouthing at the officials all game long today. Our guys didn't say much at all to the refs that I could see. I commented more than once to my son that the talking, mouthing, and complaining (flat out questioning calls) that the German team was doing would get UK players T-d up in most games. It's probably best to teach them to keep quiet.
