Rucking is one of the most important aspects of possession rugby. Teams that successfully recycle their own ball get more opportunities to score, and with opportunities come victories! Referees have an obligation to make sure that rucks do not become dangerous, which can and will happen in games played by less-than-experienced participants.
Promoting clean rucks not only decreases the likelihood of a player suffering a severe injury, but it also contributes to the overall enjoyment of the game for everyone. The effective handling of rucks should be a priority for all rugby officials, and it can improve many aspects of a contest.
