There is only one person, one factor, one anything to blame here. Rick Rypien. Completely unacceptable behavior from a player who had lost control of himself. Not that there is any evidence of this, but play this out in a chance encounter in the real world. A guy gets thrown out of a bar, and another guy heckles him on the way out. The guy being tossed attacks the heckler. What now? You going to tell him to leave the bar for three days?
Once again, there is a wide spectrum of opinions on this. The problem is, no one seems to be focused on the one thing that matters the most. He grabbed a fan. A FAN. This is so wrong on so many levels that a five to ten game suspension just does not match the crime.
So many people claiming "over reaction." Sometimes there needs to be over reaction. Sometimes there are cases where drastic action needs to be taken before something terrible happens. The head shot rules needed to be in place before Marc Savard and others had their careers put in jeopardy. This is a chance, not for over reaction, but for the NHL to make it clear that this is unacceptable before it turns into a Ron Artest moment.
