Parents interfering in their kids’ sports is nothing new. But a group of parents at Castro Valley High is taking it to a new extreme.
What started as a group of unhappy parents griping amongst themselves has ballooned into multiple investigations, an observer attending every girls varsity basketball practice and a committee that will pick the team.
It’s the kind of over-the-top behavior that’s increasingly common — parents running on the field, screaming from the sidelines and, in the worst cases, punching out officials. It happens when well-intentioned parents let their protective instincts for their children overwhelm their good judgment.
In Castro Valley, the club wielded by parents is legal clout.
