I know some “hockey families” where the kids — boys or girls — can play any sport they want . . . as long as it’s hockey. They have email addresses like firstname.lastname@example.org (assuming their name is Smith), and from the parents’ point of view, it simplifies things a lot. You don’t have kids getting into one sport, losing interest, moving on to something else. From the kids’ point of view? Maybe not so good. And I actually think it helps kids athletically to do more than one sport . . .
