Some people think, physical & verbal fighting is part of the game. Some believe these are arts to perform to defuse the against team bypassing the game law.
I disagree. I don't like fighting. The game should be full of skills and strengths, and sometimes luck too. But not fighting, cheating or acting. Yes, to make people earn more money when some players act to lose or anything else. In Cricket it might be called Betting.
One day I was watching Japan and Canada football (Soccer) match. I was surprised to see both teams are not hitting each other, they were playing hard to win! The game was so nice to see. This is called a game, not a fighting ring or money gambling machine.
Japanese audiences are well known for cleaning up the gallery after the game and Canadians are well known for their nice behavior. No doubt their football games are the cleanest and most well-behaved.
