This still feels like it should've been a good goal.
On the power play, the Panthers appeared to regain the lead when a point shot from Brandon Montour clipped off Matthew Tkachuk and into the net to make it 3-2 at 17:39. However, the goal was immediately waived off after officials deemed that Tkachuk had interfered with Quick.
The Panthers challenged the call, but after an extremely long review the decision was upheld. To add salt to the wound, the Panthers were also assessed a delay of game penalty. But was it the right call? Let's first take a quick look at the NHL's rulebook to see what we can find out.
Here's a relevant passage on goaltender interference:
"Incidental contact with a goalkeeper will be permitted, and resulting goals allowed, when such contact is initiated outside of the goal crease, provided the attacking player has made a reasonable effort to avoid such contact."
Looking at the replay, it's clear that contact was initiated outside of the crease. Given that, it means that officials took the liberty of deciding if there was intent or not. On the play, you can see that contact occurs when Tkachuk turns to try and get a piece of the puck after the shot.
Was there intent? It doesn't seem that way, and officials certainly can't know for sure.
Overall, we've seen these calls go both ways in the past, and there's definitely a gray area that the decision falls into once all the chips have been laid out and it comes down to intent. In the end, officials can choose to think the worst of a player or give them the benefit of the doubt.
In my personal opinion, that ice belonged to Tkachuk and goals like this should always count.
