If you have three defenders (including the case where one of the two
blockers is going to peel off on the set), then you probably want to use
a diamond type defense with two defenders near the sidelines (the line
defender should be almost on it, the angle defender may be off it a bit
so that the attacker can't easily hit down in front of them) and the
third defender should be deep middle somewhere (typically making a read
as to which side of the blocker to be on). If you try to get a double
block on most of the hits then you typically will give up the middle
It's also possible to play rotation defenses where the block tries to take
line. I can't see that really being viable for 4s.
Since we haven't gotten and indication of the level of play, I should also
mention that you can also use no blockers. In that case you probably want
a female setter at the net, the two male players playing sideline defense
and the other female player playing middle back. This defense is good when
your setters are slow in transition and the other teams players are short
and/or the setting is poor so that it is unlikely for the opposing players
to hit down.
You can also run three blocker systems, but they wouldn't normally be used
in coed play (or even normal play except at very high levels of play). You
generally lose more on defense than you gain on blocking with those systems.
The other thing you probably want to do is review what happened in matches
and note areas where your team stuggled and consider changes that could
help mitigate those problems without giving up too much in other areas.
Particularly transition play, both on digs and free balls. Generally simpler
strategies will help make sure you get hits but allow the other team an
