AFAIC, it's unconstitutional for school games.

I think that's a bit strong, but I understand your point.

In middle and high school, we had a daily moment of silent meditation. You could quietly pray, you could stand for a minute, or you could sit for a minute. I always thought that was the best and most respectful solution for all. (Of course, I just looked around at the girls). I've known people who thought "silent medidation" was too restrictive - I think such objections are from people who want turn religion into a show or spectacle.
