Red card rules in Rugby. They are entirely too punishing and legalistic. Think targeting rule where a player gets ejected for a subjective hit, but you can’t replace him and so have to play a man down the entire rest of the game. Red card ejections often involve contact to the head or neck area, but there is no real concept of a “defenseless player†or intent, so players have their full speed tackles analyzed in super slow motion and the ref makes a judgement call on if maybe he could have tackled the ball carrier slightly differently. The ref usually decides that yes, the player should have been able to control all aspects of the tackle at full speed and the guy gets ejected. It often renders entire games uncompetitive or drastically changes the outcome. Some examples:
Italy reduced to 13 players vs 15 because a guy got a red card while making a tackle, but he was also the replacement for a guy who got injured and they had no more qualified subs, so they lost 2 guys for one tackle.
This is the Rugby World Cup final from October, New Zealand vs South Africa. 1/3 of the way into the game, the NZ team captain got a red card for a high tackle in which the runner basically turned and ducked into his arm as he tried to wrap up. NZ had to play the last 2/3rds of the game a man short and without their captain, and lost the game 11-12. Again, this was for the World Champion title. Outcome influenced by some dweeb sitting in a room of TV monitors reviewing a tackle in super slow motion and deciding he knew what the player could have done differently (This one gets me a little heated because it’s my team).
Again in the World Cup (pool play), Curry for England gets ejected from the game only 3min in due to basically incidental head on head contact with the ball carrier (first 40sec of the video). England played 76min with a man down, but did manage to win by playing keep away. As an aside, I was at this game and it was pretty fun. Never seen so many drop kicks in one game in my life.
A key point to notice in all of these is that it is the replay guy (the “TMOâ€Â), not the ref on the field, making the calls well after the fact, and they then bring the play back. Think the replay guys calling down to the on field refs in football to reset the game several downs prior for some penalty that they saw in slow motion replay.
