So all hope is not lost for the multi-sport kids! That’s great!
I have a kid who loves playing a lot of different sports – technically he is a 4-sport athlete. But he never has wanted to do club-level anything – despite being good enough. I was always the one pushing him to do club sports (my thinking is that if he went to the big local high school he possibly wouldn’t make a couple of the teams), and he was the rational one saying he didn’t want the pressure of travelling to tournaments all the time. He is now at a small private school, so he gets to play something every season. In that sense, I see us paying for EC sports in a different way than a club experience- by paying for the school instead of the sport. He gets to play for fun, but I had to “let go of the dream” of college recruitment. My dream, that is, not his. 
I still worry about the injuries. The stats on youth knee injuries are pretty alarming. And don’t get me started on concussions.
