I applied for a position in my local town for a volleyball coach position . Im 23 years old. Do you have to know the game very well ??? Cuz i was once a cheer coach for little girls.. I know how to do stretches and how to play the game but i'm kinda confused on the plays and positions. All i don't know is how to switch positions. and stuff like that.. Do you have to know the game well to become a coach?? it's for junior high girls ages 11-14
