It's as simple as this. Until the suspensions are meaningful, stuff like the what happened to dahlin will continue to happen. obvious shots to the head resulting in injury should be 5 to 7 games minimum and double for each following incident. After a certain amount of incidents it becomes 1 year vacation.
I'm not saying every little hit, but ones which look like the intent to injure, head shots, elbows, checks to the head and neck area.
2 games on cernak is not good enough
