Strategies for a 5-1 serve receive are slightly different
In a 5-1 volleyball offense, a team has 1 setter and 5 hitters. The setter sets in every rotation. This is different from a 6-2 offense in that not only does the setter set when playing on the back row, but also across the front row.
When the setter is on the front row...
Here are some examples of 5-1 serve receive rotations for teams running a 5-1 offense.
When the Setter is in Left Back, it is only illegal for them to overlap Left Front or Middle Back players.
Setter in Left Front only has to worry about overlapping Left Back or Middle Front.
Setter in Middle Front only has to worry about overlapping Left Front or Right Front or Middle Back.
Setter in Right Front only has to worry about overlapping Middle Front or Left Back.
Setter in Right Back only has to worry about overlapping Right Front or Middle Back.
Setter in Middle Back only has to worry about overlapping Left Back or Right Back or Middle Front.
In the photo above, the Middle Front player is stack to the right side of the court.
Remember, these are just basic serve receive rotations. For example, in the drawing above, let's say the MF player wants to hit outside. The MF can move over close to the left sideline (as long as they don't overlap with LF) to be in a better ready position to get outside for an approach to attack.
Always adjust your line up to fit your teams needs.
