i am in a similar situation but have 3 girls who have never played, one that has played a little, and 3 that are half decent.  our first game is next weekend.  besides the basics, throwing, catching, and a little bit of movement, there really isnt enough time to get these new players game ready in the last training session.  so this week they will go home with worksheets to do to learn basic rules, positions, and center breaks, so they arent completely clueless, and will be spending my last training session, just doing center breaks, getting the ball down the court, and basic defence. where am i going to put these new players?  at first just in the wings so they can find their feet, and then give them a go at most positions, as they are only and learning.  its still meant to be fun and lots of learning for all.  thats my take on it.  the year will be as successful but that may not be counted in the number of wins, but how much they learn.
