What do the volleyball coaches need to know about volleyball?

Answer 1

Volleyball coaches need to be able to know a lot.

1. You need to know ALL of the different hits that are illegal and legal hits to do in an actual volleyball game.
2. You need to know different formations in volleyball. Especially important for high school coaches to be able to identify different plays and formations.
3. You need to be able to know how to do practice drills and how to get the practice drills incorporated with the actual volleyball skill.

Those are the most important things a coach need to know. There are many more things out there though.
