Because Joel Quenneville has never had a tantrum on the sidelines ever...
Give me a break. Shit happens. He hit a pane of glass he probably expected to be like every other pane around the rink and he knocked it over. The reason he did it was the Ducks are classless. But all the focus is on him? Weak sauce.
I'm shocked that in the hockey world, where hot heads are a dime a dozen that anyone gives a shit.
