When I asked Dan Muse about his 0-for-6 record in challenging goaltender interferences after a win over the Devils on Feb. 26, he made clear that he wouldn't be deterred by ending up on the wrong side of the challenges so far.

"I know what the record is," he said. "Honestly, I'm not too concerned with that. Just keep challenging until I get one or I don't. We'll see where it goes. But I'm going to go off of what I feel is the best thing in that moment. And sometimes, I want to back up my goalie."

It seemed like challenge attempt No. 7 would be the lucky one here on Thursday, but it ended up being one of their more frustrating goaltender interference challenges so far, and proved costly in a 5-1 loss.

It was a 1-1 game in the second period, and the Penguins were on the penalty-kill after Evgeni Malkin's major and game misconduct for a slash, when Josh Norris beat Arturs Silovs with a wrist shot to take the lead.

Immediately, though, this looked like a good case for goaltender interference. Josh Doan clearly bumped into Silovs' blocker, while in the blue paint, as the shot is flying through the air. Kris Letang, while tangled up with Doan at the net front, does eventually push Doan into Silovs, but only after Doan first makes contact with Silovs. In isolation, Letang only pushing Doan into Silovs would have been incidental contact. But because Doan was the one to initiate contact, this looked like clear interference:

The NHL's war room in Toronto disagreed. They called it a good goal, putting the Penguins on a 5-on-3 penalty-kill for the failed challenge, in addition to the remainder of the major penalty on Malkin. They managed to kill the penalties, but it proved to be a momentum-swinger.

"My view on it is it is goalie interference," Muse told me afterward. "Their player skated in the blue paint, made contact with our goalie, which affected the play, which is the rule. He came in and made contact. Afterward, there's a little bit of a push. But he initiated the contact in there. So by the rules of the goalie interference, I still feel like it's goalie interference, and it seems like it changes day to day right now. And so people can maybe question some of the challenges I've made that have been lower percentage. This one, I thought, was pretty clear."

Silovs, too, was frustrated about yet another call going against them, and one he believed would finally come out in their favor.

"(Doan) touched already prior to the push (from Letang)," Silovs said. "So I don't know what they're not seeing. I have no idea. Like, it always goes against us. Like, we challenge, we lose, we challenge for our goal against, it doesn't matter. ... It happens too many times against us, it doesn't count. We score. There's a goalie interference and they score, it's fine. I don't know what is a goalie interference anymore here in this league. I have no idea."

There's no good explanation for why this keeps happening, especially seeing some nearly-identical goals end up not counting in challenges elsewhere around the league, sometimes even within the same week. Abstaining from challenges entirely isn't an answer. Muse doesn't just need to "yell more" at the officials, despite the pleading from some fans. He does that plenty, even if your TV broadcast doesn't show it in its entirety. And regardless, those referees aren't the ones making these calls anyway.

At some point, the league needs to crack down on something -- either providing clarity to the teams around the league on what they're missing, or ensuring more consistency in its own calls.
