and you know for certain that these injuries are solely the result of fighting (which is what these players did 3% of the time) and not sticks to the head, elbows to the head, pucks to the head, clean and dirty open ice hits, clean and dirty hits against the boards...you know the general effects of playing hockey.
But yes, it's those evil nasty fights (where at times *maybe* 1 punch connects) that's to blame
You want to get rid of all this. Ban hockey. You can't pick and choose. We know there are little girly men who want fighting gone. If they get there wish, 10 and 15 years from now there will still be Odjicks and Parkers suffering.
Clearly blows to the head are incredibly bad for the human brain and fighting is something that, I feel, can easily be eliminated from the game without drastically changing the game. The trend has definitely been towards fighters having major issues with symptoms and I don't think its a stretch to assume that the fights could be a cause here.
The "girly men" comment is childish. We tend to forget how vulnerable and important the human brain is. Check the video below.. Maybe NSFW for some.
