Whether you are a player that is part of the officiating crew (2nd referee, linejudge, scorekeeper, etc) or a paid official, your attitude has a great deal to do with how well you officiate the game.
How you approach your duties and responsibilities as an official influences how much you enjoy the experience officiating.
In club volleyball, players often need to help out filling officiating duties. For example, in juniors, often teams provide officials.
As a player, you may not feel you want to be involved. But I would suggest you use this as an opportunity for you to make the experience for everyone better. You can also learn a lot by officiating the game.
For instance, the "player perspective" is much different than the "referee perspective". The players are often thought of as seeing things from the inside. Players are, "inside, looking out". The officials are, "outside, looking in".
Seeing things by being on the "outside, looking in" can be very important because often players being on the inside all the time get so close to what's going on they can't really "see" what they need to.
By being on the outside looking in, you have a chance see things from different angles. By being an "observer", you see things differently and therefore you can learn a lot about what you normally wouldn't have learned before.
Also, if you have experience officiating, you have a better understanding of why officials call what they do. The less you are surprised, the easier it is to understand what to do as a player when that situation presents itself again.
Also, it's just a good idea to help everyone else out. As an official, the better you are at doing your part, the better the match will go. For instance, if you are the R2, you can help out the R1 and scorekeeper helping the match run more smoothly. As a line judge, the better you are at making calls, the better the rest of the officiating team is going to look.
Wouldn't you want players from other teams to officiate your game well? Let's learn the rules and do our part and maybe we can inspire others to do the same.
