Back Row Attack

[bbsbvb83]

The following elements appear to be present in this play...

- libero is positioned on or in front of attack line
- libero sets ball using overhand finger action
- next hit (attack) takes place while the ball is entirely above the height of the net
- attack is completed (ball completely crosses the vertical plane of the net)

As a result, the proper signal sequence for the R1 is...

- Award point to appropriate team
- Signal illegal back row attack on offending team
- Point to libero to indicate the violation is a result of her set

This looks like a good call to me.
