One of the most important parts of serve receive is watching exactly what the server does ..how they approach the ball where they strike it, what type of a contact .. spin or floater. Etc with the height of the players today and say three players grouped together at the net it can be very difficult to see the server .. the defensive player does have to move to see the server but not way out of their normal serve receive position. Unfortunately there are coaches that use the fact that this violation is rarely called and will even stack the back row player in line with the server .. the balls trajectory is critical. It is hard for the referee to call this however there are specific times when the ball goes directly over the screening players and no effort has been made by the player to leave a space between themselves .. I don't call it like I used to.. but when I did I mentioned it in the first team meeting and I suggested for the players to leave a body space between themselves or bend over when transitioning ... The tough thing is when you call it, it needs to be a really good example of a screen and then you are on line for the rest of the game for not missing anything .. because you have raised the bar .. if a defensive team complains .. Advise the captain and then if they don't make adjustments call it! Also for the those writing the rules if it is rarely called consider taking it out of the book! I think it is a valid call because there is an unfair advantage. Trainers need to train referees to call it and inform coaches it will be called if you don't want a backlash from the coaches when it gets called.
