I was pissed at first, but after seeing the slow-mo replay, it is what it is.
It wasn't a high-stick, which is the only part of that play that is reviewable once a goal is called. I thought Malkin interfered with Hank strictly by the rules, but that's not reviewable, so whatever.
When I first saw this, I thought it was definitely goaltender interference. But watching it carefully, I agree with Woodhouse. It really looks like Hank loses the puck, and actually brings his hand up to block Malkin's stick away. The puck goes over Hank's blocker shoulder, not his glove shoulder, and he's staring at Malkin the whole time, not the puck.
I *DO* think goaltender interference should be reviewable, but I don't think this is goaltender interference, since it really looks like Lundqvist is actually initiating the contact.
