Now I'm starting to see why Mike Smith has so many concussions. Yeesh. http://blogs.thescore.com/nhl/2013/03/2 ... f-the-way/
I still think the Shaw elbow was a blatant cheap shot and intent to injure, but I can see the argument for Edler.
I can still remember when Roy would occasionally throw a good check into the boards on anyone venturing behind the net. To be honest, if you want to cut down on goalies wandering, instead of doing a trapezoid, just make them fair game outside the crease. Of course, I'd say that if you're gonna do that, then you also have to enforce rules against crashing the net, which you should do anyway.
