With those penalties I suspect that the players will amazingly learn how to control their actions even though they are "warriors" and so many things happen in "the heat of the action".If I were in charge of setting the rules in the NHL here's what I would do:
Staged fighting - 5 minute penalty, 3 game misconduct, 3 strike rule.
Spontaneous fighting - same as above but no 3 strike rule.
Cross checks above the shoulders, high sticking, boarding and charging - 5 minutes, if the player is injured 2 automatic game misconduct. Additional games depended on severity of injury.
Elbowing to the head, 5 minutes. This is a tough one since flagrant headshots (Stevens vs Lindros) have declined noticeably.
BTW, for all those that claim there will be an increase in stickwork you could throw in similar penalties for spearing and flagrant high sticks. I also agree with slightly lesser penalties for spontaneous fighting.
It will still be an aggressive, hard hitting game for very big, strong and well conditioned men, just less goonery and codes of conduct.:frusty:
