It really is. One thing that's just come to light for me is how awful public school sports have become. When I was a kid, if you played on the school basketball and volleyball teams, you practiced 4-5 times a week, either before or after school. We had relatively good coaches, were taught how to play the game and played against good competition. Teams were rep teams, in that they only took the best 12 and players were cut. This circuit didn't really interfere with hockey or other winter sports and thus you could "do both".
Now it's a bit of a joke. Practices are often held during recess a couple of days a week and while they still do cut kids, they don't cut them based on ability per say. Sometimes you get cut so someone else can "have a turn". Teams have 20 kids on them, so playing time is minimal and they don't even play by the rules (volleyball referees don't call lifts and teams were getting upset that one kid was spiking it?). So now, if you want to really learn and excel in those sports, you have to play for a local rep team and of course that directly competes with hockey and kids are forced to choose which sport they want to play.
