I'm probably posting this too late for it to be of any value to you, Larksy, but I would suggest a couple of things. First, get there early. Allow plenty of time to relax in the dressing room. Get into a basketball frame of mind. You don't want to be rushed to get onto the court. The extra time (hopefully with your partner(s) ) will relax you.

Second, don't go looking for stuff to call, just so that it looks like you're doing something. Let the game come to you, just like any other game. If you don't have a whistle for the first 5 minutes, that can be fine. Don't get antsy and make a borderline call, just so you're "pulling your weight".

Try to relax. Enjoy it. I hope you don't get stuck doing 3 years of those games, like I did! Good luck!
