Get a dry erase marker, and write on the back of your hand:
1. Each team's captain
2. The setter and his/her opposite.
3. Refer to your hand very quickly until you get the hang of who is who.
4. When you are up, remember that you need to signal legal BRA's. In some places they don't care if you do, others will be all over you if you don't. but the more you use the legal BRA signal (i.e. the more you see legal BRA's), the more comfortable you will get with seing and looking for the illegal ones.
5. See if you can do some JV/Varsity matches, if you are not doing them already. You know how pressure gets the mind to concentrate, it will happen here too.
6. If you can, get a veteran guy or gal to work a match w/ you as an observer/helper. JH, Fr. or maybe JV won't care if you have help, and it may make you feel better in your learning curve.
Once you find a way to drill the setter's number in your head, the whole floor will open up to you!
Also, go to a HS Varsity match, follow the crew around in pregame, then grab a wheel and work with it. Get a good 5 set match, and you will feel comfortable with it.
Be patient with yourself, if you are coming in from other sports w/o a lot of
VB experience as a player/coach/fan, it is easy to get lost. Work as hard on this as your do your BK rules and mechanics, and it will come. When you think about your hoops experience, you have so much experience in your brain, that a lot of things even good HS guys have to think about you do as a matter of course, w/o thinking.
VB gets to be that way too, if you work at it.
Dollars to donuts, sometime early next season it will all come into focus,and you will start to see it, both BRA's and overlaps.
