Volleyball coaches look at the ratings of opposing team passers to decide who to target with the serve, but that might mask opportunities.
At the 2019 AVCA Convention I attended a session by USA Women's assistant coach Luka Slabe where he suggested less is more with regards to scouting.
The first training is months away, but a professional volleyball coach's work isn't just on the court. For me the 2015-16 season is already underway.
In terms of causing your opposition offensive problems, sometimes attacking Zone 1 can be an extremely useful serving strategy.
