In Round 2 an opposition player was called to play on from full back when kicking out. He walked the ball back over the line. According to the rules this is a ball up at the top of the square. The umpire just paid a point. I knew the rule and yelled out to the umpire. Unfortunately I made the mistake of swearing so the umpire then paid a 50 against us.
The coach should never abuse the umpire or the opposition.
