Honestly, all the league would have to do to take this seriously is stop penalizing the result of things like hits and start penalizing attempts to hit the head consistently. Fighting is another issue, tough.
I agree about the attempts. Injury should certainly factor in to the length of punishment but right now it plays way too big of a rule. If a guy is luckily enough not to get concussed (or if the symptoms of that concussion have not manifested themselves yet), that doesn't make the play that caused it less dangerous.
It's why I think elbows and attempted elbows to the head should be punished severely. That's not a hockey play gone bad. It's a deliberate attempt at a headshot.
I'm also surprised that the NHL doesn't have a more established support system for former hockey players. Most of these guys didn't go to college and even lived away from home as teenagers so they could play hockey. It's been the basis of their entire life. Whether you leave the game as a 27 year-old retiring due to concussions or a relatively healthy 40 year-old who just won the Stanley Cup, it has to be a massive adjustment.
Hate the guy in the ice but this goes to show you that most hockey players are just great persons of the ice. Man trying to play after receiving such news is mental toughness kudos Carcillo.
Pro leagues really need to do a better job in preparing these guys for the life after hockey.
Ask them to coach some minor leagues, get into GM stuff, become a player agent, analyst, inside..don'tforget them because they are retired.
