It is healthy for kids to play team sports. I recall that when I was not particularly good at some athletic endeavor, for example sprinting in a relay race, I would try to make up for it with a positive attitude or other such team building attributes. Being a part of a team isn't all about being the person that scores the goals/points or finishes first, it's about learning to support people on your team even when they can't hit the backboard. When I was a kid we all read the play "Our Town" in class and we all had roles to play/read. Some kids were better readers than others, I'm sure some of the poorer readers didn't look forward to these exercises. Should that also be removed from the curriculum? Challenge breeds character, the key is having an in tune educator at the helm of these team endeavors. Oh, and don't let the kids "pick" the teams, that's just cruel. But to eliminate team activities from school is a horrible idea.
