From a big picture perspective the Pittsburgh Penguins acquisition of Ryan Reaves on Friday night isn’t really a major deal. Normally teams swapping fourth-liners and 20 draft spots wouldn’t be the type of move that would move the needle or send any sort of a ripple through the NHL.

This one is a little different.

This is the Pittsburgh Penguins — the back-to-back Stanley Cup champions — ever so slightly deviating from the path that made them the best team in hockey the past two seasons.

As general manager Jim Rutherford put it on Friday night after the trade, “We’re getting a little bit tired of getting beat up game after game.”

Rutherford was critical of the way superstars Sidney Crosby and Evgeni Malkin were treated during the postseason and talked about how his team would pretty much have to add one or two players to take care of it since the league does not seem to protect its stars.

Commissioner Gary Bettman quickly dismissed that criticism upon hearing it.

On Friday, Rutherford added that guy and the discussion quickly turned toward the element Reaves brings and what it might mean for the Penguins.

Coach Mike Sullivan talked about how opponents played the Penguins “harder” this past season and that they expect it to continue again this upcoming season, and that Reaves can help with “a little pushback” and how teams “take notice” when he is in the lineup.

Reaves himself talked about what he can provide for the Penguins’ stars.

Here he is, via the Pittsburgh Post-Gazette:

“It’s more just making sure everybody on the ice knows I’m coming every night. You go run one of my guys, you’ve got 230 pounds coming right back at you. Sometimes that makes guys think twice. When you’re 190 pounds soaking wet and you’re going after somebody on my team, and you’ve got somebody that’s 230 coming after you, sometimes it’s a deterrent, sometimes it’s not. But I think that’s kind of how I’ve established myself over the last year.”

This isn’t the first time the Penguins have been inspired to go down this path due to the treatment of their superstars.

During the 2013-14 playoffs New York Rangers defenseman Dan Girardi and Marc Staal made a habit out of using the back of Crosby’s head and neck for cross-checking target practice in front of the net.

The response from Pittsburgh was outrage that nobody responded and for the team to add some sort of muscle to help take care of that.

Then this happened the following summer.

Steve Downie on protecting Sidney Crosby and Evgeni Malkin: "I can guarantee there won't be any liberties on those players this year." — Pittsburgh Penguins (@penguins) July 4, 2014

That guarantee went unfulfilled.

Liberties were still taken against not only Crosby and Malkin, but also against the Penguins’ other superstar, defenseman Kris Letang. He was on the receiving end of two brutal hits that injured him during the year. One resulting in a lengthy suspension to Zac Rinaldo, and another from Shane Doan that knocked Letang out of the lineup for the remainder of the regular season and the playoffs.

They also tried it with Tom Sestito when they brought him in on a pro tryout contract. He ended up playing 17 games in two years with the Penguins. He was ejected from two of them.

Here he is at the time of his initial tryout talking about what he wanted to provide.

“When you play other teams and they have somebody who not only can play but can run their other guys, you see them holding off,” Sestito said. “They’re not going to be running other guys. Their third- and fourth-line guys aren’t going to run your guys.”

The names change. The idea remains the same.

Deter. Make them hesitate. Make them think about it. Answer back.

Still, the abuse continues.

All of this is a little unfair to Reaves because to his credit he has worked hard to improve his game as a hockey player and to be a little more than just hired muscle. He has worked to adapt his style to the faster NHL and to improve his play defensively. There was evidence of that this past season when he set career highs in goals and points.

If the focus on this acquisition were on that, or on his ability to forecheck, this would simply be a trade involving a couple of fourth-liners and we wouldn’t be talking about it right now.

But we keep going back to the presence, and the element, and pushback, and protection, and deterrence, mainly because that’s what the Penguins seemed to be after with this trade. Or at least what they seem to be selling.

So will any of that work? Can Reaves actually provide that sort of protection?

There is no doubt he will be willing to respond after the fact, because even though his fight totals have decreased in recent years he is still a willing heavyweight.

The issue is whether or not he can stop even a little bit of the abuse toward his teammates by making opponents like Washington’s Tom Wilson or Columbus’ Brandon Dubinsky (two of the biggest thorns in the Penguins’ side) take notice.

The easiest way to answer that now is to look at what sort of abuse the Blues — Reaves’ former team — took in recent years.

It was a lot.

Over the past four seasons the St. Louis Blues — Reaves’ former team — were on the receiving end of eight incidents that resulted in supplemental discipline from the NHL (suspension or fine), typically reserved for the dirtiest plays. The only team that was on the receiving end of more during that stretch was the Boston Bruins (10 –and keep in mind, this was a team that had Shawn Thornton and Milan Lucic for most of those years).

During one nine-day stretch in 2014 the Blues lost T.J. Oshie and David Backes to head shots. The two hits resulted in seven games in suspensions while Oshie and Backes both missed playoff games. Reaves was in the lineup both nights.

The next season Minnesota’s Marco Scandella was fined for an illegal hit to the head on Oshie. Last year New Jersey’s Bobby Farnham was hit with a four-game ban for taking a late, cheap run at Dmitri Jaskin while Reaves was on the ice. There are also several other borderline hits that did not result in supplemental discipline (like this, and this, and this).

This isn’t to suggest that Reaves is bad at his job or that he is somehow responsible for those plays.

It is to point out that dirty stuff is still going to happen to star players whether he — or any player like him — is there or not.

Players like Tom Wilson, and Brandon Dubinsky, and Bobby Farnham are paid a lot of money to rattle the cages of players like Sidney Crosby and Evgeni Malkin. That is what they do. That is their role and they are going to do it whether there is a physical element in the other team’s lineup or not.

The only thing that can stop it is a significant crackdown from the league to hand out harsher punishments when it happens.

It is very possible that Reaves can be a useful fourth-liner for the Penguins. He will play physical, he will be aggressive on the forecheck, he might chip in a few goals. Is he better than whatever alternative options they could have had for that spot? Or what they had in that spot a year ago? That remains to be seen.

The cost to acquire him really isn’t that high. Oskar Sundqvist seems to have limited upside and the difference between the No. 31 and 51 picks is typically insignificant, especially in what is thought to be a weaker class.

But if the Penguins are hoping for Reaves’ presence to stop opposing players from taking liberties against their stars they are probably setting themselves up for disappointment.

All it might do is get them the occasional pound of flesh in return after the fact and whatever satisfaction that brings them.

Maybe that is all they are looking for. Maybe it is a message to the league itself.

Whatever the reason, it is something they did not need on their way to consecutive championships.
