Whether it was intentional or not, I hope they suspend him. You can't tell NHL players to play without passion, but being upset about your team giving up a goal, but you need to express that anger in a way that doesn't endanger your teammates. Swinging a stick like that through the crease is just brainless. There's not all that much space in there to begin with, and goalies fill a pretty good chunk of that.
Idiot.
