Well at 14U rec most of those girls won't be playing HS softball unless you are in a small town with a small pool of girls to chose from and if there are a couple you have probably already figured out who they are.
What I would do is focus fundamentals, you can check out the internet...fastpitch.tv has lots of good video that can show you different drill instructional video etc, I think there are also some ASA sponsored videos with good trips and drills. You can always come to this board and ask for advice about any topic and we would be happy to help. Even if some plan to go on to HS ball stressing the fundamentals will only help them. Throwing correctly, throwing to the correct bases, teach a sound fundamental swing, help your pitchers understand the fundamentals, etc. Simple drills and situational practice scenarios help a lot. I don't think I could coach two team, I have a 14U rec team myself right now and that is more than enough.
Good luck and keep coming back
