Standing on the visiting bench, Penguins coach Mike Sullivan shook his head and said, "I don't know."
Oshie sat on the Capitals bench through the first couple of minutes of the video review and looked at one of the monitors there hoping to see definitive evidence that the puck was over the line.
Oshie couldn't find any, but he also didn't see anything that showed the puck didn't cross the goal line.
"We have the [monitors] back behind the bench, so I went to look at those, and all the views that I saw, you couldn't tell if it went over or not," Oshie said. "[Murray] was covering it up. So I figured at least it was a goal on the ice, so if it's 50-50, it's going to be a goal."
Capitals coach Barry Trotz said he was "confident it was a goal," but he remembered some video reviews didn't go Washington's way this season, "so, you always hold your breath for a second."
Eventually, NBCSN showed a replay angle in which there was clearly some white ice between the edge of the puck and the red goal line. That replay made its way onto the center ice scoreboard video screen, bringing cheers from crowd. By then, Oshie was back on the ice and standing in front of the bench, eagerly waiting for O'Rourke to end his conversation with officials back in Toronto.
Finally, O'Rourke took off the headset, stepped back and announced that the video review confirmed that Oshie's goal was a good one. That allowed the Capitals and their fans to celebrate again.
It was the first playoff overtime goal of Oshie's eight-season NHL career.
