Apparently he shot himself in the chest, so his brain is intact...I'm sure whoever the NFL contracts to study these things will have plenty to look at.
Sadly, my first thought when I heard he died of a gunshot was "did he shoot himself in the chest?" This is really, really, sad and horrible. No sport, no matter how entertaining, is worth having this kind of thing happen.
I don't care if it ruins football as we know it, head hits need to be removed from the game altogether, or I may have to find a new favorite sport. I'm not sure I want to encourage that, even if the players are willing participants. I know this is a visceral reaction to the death of a player that I was particularly fond of, and we'll see if I really have the guts to do something like that when the season starts.
My wife and I were just debating about my son (8 years old) playing flag football later this year. He plays basketball, soccer and baseball, all very well (He has a GREAT basketball coach ).
She does not want him to play even flag football because she knows he will be good at it and she does not want him to like it, thus leading to later issues with denying him from playing tackle football.
I am starting to think she may be on to something.

When this head injury stuff started coming out, I decided that I wouldn't let my kids play football until they are 16, unless there are major changes to the sport by then. Not because I think it'll reduce the chance of head trauma, but because at that age I'll be able to sit down and explain the risks to them, and they can make their own decision.
