Yeah, the media has a little bit of fascination right now and is anxious to be the next one to report a "football-related" death. I think it's sort of this year's Shark Attack story. Doesn't make it any less sad. I cannot imagine what those parents are going through. And there's certainly a decent cohort of people who would happily shut down football entirely, because they don't like it.
I keep track of it more, but every year there are a few sad cases where youngsters die playing baseball. More often than not, they just happened to be playing baseball when they died -- could as easily have happened if they were riding a bike, playing tag in the back yard, or on Space Mountain.
That said, my wife and I decided not to let either of ours try football till they were past 6th grade. As much as I love the game and would never dream of telling another parent how to raise their child, I was relieved when mine both opted for other sports (baseball, track).
