For beginners, tracking setter and opposite, knowing whether the libero is before (normally) or after (not nearly as often) the setter, is a good start.

As you get more experienced, recognizing certain serve receive patterns, which player is playing which position, and which position should be in which spot on those normal patterns, will help.

In any case, try to develop a system in which you can recognize by looking at the players and their positions, and not nearly as much looking at your lineup card.
