Lacrosse most definitely is a youth sport experiencing growth in Connecticut. It's tough to predict where it will go in the future though. I have no idea how many players are required to play the game, or how many you need on a roster, but I do know that the only reason that growth like this can happen, is that there is room to grow. The question is whether or not it will sustain once there isn't room to grow anymore, and the number of kids starts to far exceed the number of spots on the fields.
I know nothing about the game except there was a guy that played lacrosse that lived on my floor in the dorm (it was a club sport, I think it still is and I didn't know anybody else that actually played, no idea how many players there were) and he would come back from wherever they played or practiced whatever, with his arms and legs all cut up and bleeding all the time. It was because they always played on fields that weren't well taking care of. I always asked him why he didn't at least wrap his forearms or wear higher socks or something, if they're diving and rolling around in gravel filled fields and parking lots to play. He would just always shrug and drink more beer. Much respect for athletes that have no fear or hesitation, of going to the ground in a gravel filled parking lot, to play their sport, but you figure that if you do it a couple times, and you're picking pieces of gravel out of your legs and arms, after the day, you learn. Never understood that part of that dude.
Anyway, the sport is clearly in a growth phase at the youth and high school level in the state. Sooner or later, though, the same thing that happens to all youth sports, is going to happen though, and that's parents. Parents want their kids to have playign time, and they want their say with the coaches. When the numbers of kids start to outnumber the number of spots on the field, and especially, the number of decent coaches, that's when we'll know if it's something that will sustain, or it will contract again.
All those kids should be playing football when they get to high school anywayl!!!
