I haven't commented in this thread yet but I want to put down my thoughts.
What Sestito did was the type of action that has become necessary for us to take. Other teams take atrocious liberties with our star players, and expect no punishment by the referees (because there never is any) and expect no punishment from the league (because there never is any) and expect no retaliation from our players (because there usually has been none). We have no control over the former two, but the latter one, we can change, and apparently we are changing it.
The league has made it clear that they will not punish anyone who attacks our stars - in fact they reward it. So, as people have pointed out, our style has needed to change. It was only the previous game against the Kings where they ran our goalie, outrageously and blatantly, and of course got no penalty.
So our team needs to take matters into their own hands. Any time a guy takes a run at our goalie or our star forwards, we have to attack them. Attack the person that ran us, but also their star players. An eye for an eye and everyone's blind - but I'll take that over some psychopath stabbing me in the eyes and leaving me blind while he can still see.
I like this style of play, sticking up for each other.
