Oh, my, Trumbull - a couple of us have done a fair bit of softball coaching. I did 20 years, including 8 years of high school varsity asst coach, summer ball, etc.. Ursusminor did JV asst coaching, as well as being "Momma Bear" to a good D1 club team. TonyC, I believe, also has good experience in this area.
I love coaching softball - love it, love it, love it. But, part of the reason I love it is that it's complex and multi-faceted, which makes it a tough game to coach without some help or experience. It's really too deep a topic to get into on a message board. In all seriousness, PM me. I wouldn't mind a bit talking to you about it. Are you in the Trumbull area, or elsewhere?
As far as JV goes, I always thought that was, in some ways, the most interesting level to coach. On several occasions, I chipped in a little time to help with our JV team. What makes JV interesting to me is, it really is a pivotal point in a programs' structure - it's where certain players are going to develop enough to become varsity-quality (whether this year, in "call-up" situations, or next), and certain players are going to "hit the wall" as far as their softball career is concerned. People, both players and parents, sometimes forget that JV stands for "junior varsity" - which means, unlike freshman ball (which is purely player skill development), not every kid is gonna get "their turn" even-handedly. But, neither is it varsity, where winning matters - for league standings, for state tourney qualification and seeding, results are in the paper, etc. - so, while winning is desirable, the #1 priority is turning kids into potential varsity players.
