It is interesting that money is cited as a reason that my county (Broward) will not be participating - the club teams have managed to fund the sport, this far.
you are correct, there are very different parameters once a high school sport is elevated. Especially one as capital intensive as boys lacrosse. In many east coast states outside coaches (outside of school and then school system/district) can only act as assistants and many cases can not. Could you imagine if Balto City/County, or the state of Maryland for that matter allowed coaches outside of the school systems?
PA just went varsity and a bunch of the top Western PA schools thought they were going to stay in the MidWest so they could continue travel, tournaments, fall ball activities, ect.......and they found out very quickly that they either had to join or fold the school affiliated "club". Basically, they had to comply with all the varsity rules or nothing. Essentially the mandate came down and schools have to accept it if they want their school to have a team. It always varries from state to state though.
I know that some cash strapped school systems require small payments to offset costs for varsity sports, but that is usually capped at $50 bucks. I'm not sure what FL is going to do, but I wouldn't think that they would allow the dues for a varsity sport to continue at the level that they currently are.
