We've done this to almost all sports. Hockey, volleyball, softball, baseball, basketball even dance. And it's sad, but that is what it takes for those who want to compete at the highest levels. When I was a kid and into high school, a person could participate in multiple sports. i.e. Football, basketball or wrestling, track then baseball. I don't see very many kids doing that anymore. If they don't focus and specialize on one sport they won't make their HS varsity team or the club team they want. I'm not sure exactly what has caused this. My guess is its the culmination of parents living vicariously through their children. Both of my kids could've continued with 2 or 3 sports but they were forced through circumstance to really focus on only one and treat another as a sideline. Granted neither had/has D1 talent but it's sad that they could not participate in all the sports they would've liked to. If you don't commit to a sport year round, chances are you won't be playing that sport for very long.
Yep!
Once coaches realized how much money they could rip from parents...well, things changed.
Now, with that said you can still be varsity in different sports but the time commitment is brutal and there are a lot of coaches (especially if you get into club/select) that don't want "their kids" playing other sports.
