Eichel, Ryan O'Reilly and Brian Gionta each scored goals for the Sabres during a first period in which they had three power plays and outshot the Penguins 21-13. It still wasn't the perfect period by any means; there were stretches where Pittsburgh hemmed the Sabres in their own zone and Anders Nilsson had to come up big.
Those types of stretches, defenseman Jake McCabe said, were bound to happen. The Sabres expected them against a team as skilled as the Penguins, just like they expected Pittsburgh would eventually earn its own power plays and find the back of the net.
They did both of those things in the second peirod. Justin Schultz put the Penguins on the board with a goal on the rush, while Evgeni Malkin scored with a one-time shot on the power play later in the period to make it a one-goal game.
"That's going to happen," McCabe said. "It's a world-class player making a world-class shot. That stuff happens. We get to the second period and its 3-2 going into the third that's a great spot on the road obviously.
" ... Stuff like that happens in a game and you've got to respond accordingly, which we didn't."
The Sabres weathered the storm a bit more in the third period - they killed off two penalties - but allowed the Penguins to finally tie the game on a high deflection off the stick of Jake Guentzel with 3:46 remaining. The goal was reviewed to see if Guentzel had scored with a high stick, but the call stood.
"The high-sticking rule as it is is hard to overturn," Sabres coach Dan Bylsma said. "So, whether I think it's a high stick or not, I know it's' rarely one that's overturned."
Sheary's goal, scored at the back door after receiving a slap pass from Schultz at the blue line, followed less than a minute later.
All the while, the Sabres had gotten their share of chances to get that elusive fourth goal. They ended the first period on a power play that saw them earn multiple scoring chances, Evander Kane had a breakaway attempt almost immediately after Schultz's goal in the second period, and Buffalo got one last chance with the extra man when Schultz was called for a delay of game with 1:51 remaining in the third.
But still, with all that being said, Eichel felt his team didn't push hard enough.
"We gave them way too much," he said. "A team like that, you can't sit back and let them just pick the puck up in their zone and skate at you. That's what we did. We just backed up on [Nilsson]. We were lucky to get as far as we did. We played a good first period, got away from what we did. That's the tale of the story and it seems like it's kind of a reoccurring theme right now with us. "
Nilsson, who made a season-high 46 saves when he first faced the Penguins in November, stopped 41 shots and was excellent for much of the night. He made multiple saves from point-blank range and was the reason the Sabres came out of the first period with a 3-0 lead in the first place.
