Is there an easy way?

IF you have a good scorekeeper, they can help you out. During your prematch discussion with your scorekeeper, tell them that there are times that you will ask them to give you the NEXT THREE SERVERS on either the right side or the left side. When you ask that question, the scorekeeper will give you the numbers of the front row players in order. Find those three numbers on the court and they MUST be closer to the net than 3 other players. If they aren't closer to the net (centerline) than the other 3 players on their team, you can be 99.99% sure that there is an overlap.

There are times that coaches come up the gol-darndest serve-receive formations that I have ever seen. When that happens, I am asking my scorekeeper for information constantly so that I can figure out what the heck they are doing (and I am usually pretty good at tracking the players on the court...but there are definitely times!!!).
