The Pittsburgh Penguins loss to the New York Islanders was no fluke.

It was a result they earned and was due to them being outplayed and soundly beaten in pretty much every phase of the game by a Islanders team that looked faster, crisper, and smoother.

It was also not the result of something that simply happened overnight.

On the off day between their losses in Games 3 and 4, defender Justin Schultz nailed a big part of the problem when he said this: “Our identity has changed over the years. We play fast and get the puck up quick. That’s what we do best. We haven’t done that this series.”

But when did it change, and more importantly, why did it change?

It has taken the Penguins two years to reach the point where they needed to wait until Game 81 of the regular season to simply make the playoffs, and then could not even scratch out a single win once they got there.

To find when it all began you can probably go back to May 28, 2017.

At the time, the Penguins were the defending Stanley Cup champions and just 24 hours away from beginning another Cup Final series against the Nashville Predators that they would win in six games, becoming the first team in a generation to successfully repeat as champions. Their recipe and identity was clear. They played fast, they didn’t let anything throw them off their game, and coach Mike Sullivan had driven home a “Just Play” mantra that became the calling card of their 2016 championship run. It applied to just about any situation.

An injury to a significant player? Just play.

Don’t like a call that was or was not made on the ice? Just play.

Facing some adversity and down in a series? Just. Play.

In the years between their 2009 and 2016 championships the Penguins had become a deeply flawed team that was short on depth around its superstars and had rapidly developed a tendency to unravel whenever things didn’t go their way. They were almost like petulant children that would lose their composure when calls went against them and become almost infatuated with responding to even the slightest physical altercation. They reached rock bottom in this regard during the 2012 and 2013 postseason losses to the Philadelphia Flyers and Boston Bruins when they seemed to be playing a game where hits and responses were worth more than goals.

Starting in 2015, general manager Jim Rutherford started to reshape the team into something different.

He found the right depth players to go around the core of Sidney Crosby, Evgeni Malkin and Kris Letang, and he made a series of trades and call-ups from their AHL affiliate in Wilkes-Barre/Scranton to make the team faster and more skilled throughout the lineup. Combined with Sullivan’s mid-season takeover in 2015, it was a perfect storm that allowed them overwhelm opponents and catch fire sometime around February.

They never slowed down on their way to a championship.

While the 2016-17 season wasn’t quite as dominant and had to rely on goaltending a little more in the playoffs, the same formula was still in play.

Despite all of the winning, Rutherford was still unsatisfied with something.

He was unsatisfied with the way his star players were being treated physically. In each of those postseasons the Penguins had to go through opponents that were not shy about targeting their stars. Crosby’s postseason run-ins with Dan Girardi and Marc Staal are well documented, and they had two consecutive postseason encounters with Tom Wilson and the Washington Capitals. In the Eastern Conference Final that season there were several incidents against the Ottawa Senators that drew the team’s ire.

The day before the 2017 Stanley Cup Final began, Rutherford offered a look into where the team was going to be headed when he sounded off in an interview with Ken Campbell of The Hockey News. This is the key part:

“I hear year after year how the league and everyone loves how the Penguins play,” said Penguins GM Jim Rutherford. “‘They play pure hockey and they skate.’ Well, now it’s going to have to change and I feel bad about it, but it’s the only way we can do it. We’re going to have to get one or two guys…and some of these games that should be just good hockey games will turn into a sh—show. We’ll go right back to where we were in the ’70s and it’s really a shame.”

Emphasis added.

“We’re going to have to get one or two guys.”

He doubled down on it just days after the team won the Stanley Cup.

“We are going to try to add a player or two that maybe we can have more protection in our lineup. That’s not that easy because [coach Mike Sullivan] likes to roll four lines and you’ve got to plug a guy in that can play on a regular basis, but hopefully that’s what we can do.”

That was the moment they started down the wrong path. Suddenly, a team that had become defined by playing through things and not responding was going to get “one or two guys” to … respond. The Penguins hadn’t even finished their run at the top of the league as champions when they made the decision to start slowly deviating off of the path that got them there, all in the name of retribution and the misguided idea of “deterrence.”

On draft night that year, the Penguins flipped their first-round pick and center Oskar Sundqvist to the St. Louis Blues for Ryan Reaves and a second-round pick, a trade that has turned out to be a significant loss for the Penguins in more ways than one, and it was a bad idea from the start. Not only did they move back 20 spots in the draft, but Sundqvist has turned into a solid third-line center for the Blues (a position the Penguins spent two years and countless assets trying to fill) while Reaves clearly never fit in with the Penguins’ style of play.

Sullivan barely used him, it shortened the team’s bench, and he was ultimately traded halfway through the season in the massive and complicated deal for Derick Brassard.

The problem with that sequence wasn’t necessarily the trade itself, but what it represented.

What it represented was a philosophical shift from the recipe that worked, and there is nothing that has happened since that trade that has put them back on track.

Pretty much every significant roster move the Penguins have made since then (and there have been A LOT of them) has revolved around getting bigger, stronger players, especially on the blue line where Jamie Oleksiak, Jack Johnson, Erik Gudbranson were the significant additions over the past year. It resulted in a defense that lacks mobility, doesn’t move the puck well, and has simply zapped them of a lot of their transition game. Add that to the departures of forwards like Carl Hagelin and Conor Sheary and the team no longer has the speed and skating advantage that it used to have over its opponents.

The most confusing thing about all of it is the roster construction and many of the moves seem — emphasis on seem — to be at odds with the way the coach has wanted the team to play from the day he arrived behind the bench. I know nothing of the working relationship between Rutherford and Sullivan and whether they remain on the same page as to how the team is built, but the optics of it all just seem strange.

They paid a significant price for Reaves, and the coach didn’t play him. The general manager championed the signing of Johnson all season, and despite playing in all 82 regular season games was deemed to be not worth a roster spot in the first game of the playoffs. A team that wants to play fast and beat teams in transition and with puck possession, suddenly has an inconsistent transition and possession game because the players on the back end can’t make the necessary plays to feed it. And that doesn’t even get into general manager’s fascination with trying to even the score with Wilson in Washington after he knocked Zach Astron-Reese out of the playoffs a year ago (something that ended up getting Oleksiak injured).

Make no mistake, there were other factors at play throughout this season and the playoffs that produced this early exit. The forwards, as a whole, don’t help out enough in the defensive zone. The Islanders did a great job shutting down Crosby and Jake Guentzel. Letang and Schultz, the two defenders on the roster that can still play close to the Penguins’ style, each had a bad series.

But a bad series for individual players happens, and sometimes they are even understandable and defensible because even the best players have bad stretches.

What is not understandable and defensible is willingly taking yourself away from something that worked. That is what the Penguins did, and it is a big part of why their season ended up going the way it did.

The moves they make this summer will tell us a lot as to what they learned from it.
