With one head-snap motion, Nick Bonino of the Pittsburgh Penguins reminded everyone about hockey’s dirty little secret of embellishment.

Not the same kind of player flopping that occurs in, say, the NBA, and it’s certainly not done at the same volume seen in soccer, where diving is used effectively at the highest levels even as it is ridiculed and (occasionally) penalized.

In hockey, exaggerating a potential penalty to get a call against the opponent has long been part of the game – especially in the Stanley Cup playoffs, when everyone’s looking for an edge – and embellishment is simply reality even though the NHL has taken steps to stop it for more than a generation.

Bonino sold a high-sticking penalty against Washington’s T.J. Oshie last week when replays showed the Pittsburgh forward was never hit in the face late in Game 4. The Penguins got a power play, making it easier to hang on for a win.

Canadian TV pundit Don Cherry ripped Bonino for being “phony,” retired defenseman Mike Commodore predicted he won’t draw a penalty the rest of the playoffs and forward-turned-analyst Mike Johnson wished there was a way to suspend a player for deliberately and clearly fooling the referees.

“It’s a tough job to call those, but I think there’s times that everyone steps over the line and it’s not called,” Nashville Predators defenseman Ryan Ellis said. “It’s in the game, and it happens.”

Embellishment runs counter to the principles of hockey that prize toughness and playing through pain. Faking it simply seems way out of place. But in the modern NHL where hooking, holding and other obstruction fouls are called tighter and power plays are so important, drawing penalties is a skill that is worth its weight in goals, points in the standings, wins and possibly even money on the next contract.

“You always get guys saying they’ll do anything to win this time of year,” veteran Capitals defenseman Brooks Orpik said. “If that’s what you feel is necessary, then I guess that’s what you do. I think a majority of guys in the league aren’t comfortable doing that.”

Game officials can call embellishment minors, of course, but the league also watches for them and a panel votes weekly on possible infractions, with repeat offenders announced publicly. Since the NHL added fines and the public shaming for embellishment before the 2014-15 season, director of hockey operations Colin Campbell said, incidents that get reviewed by the league office are down sharply, from 35-40 incidents per week in 2014-15 to just 20-25 this season.

Plays like Bonino’s bring fresh headlines, but Campbell said he feels embellishment is no longer rampant after saying in June 2014 it was “out of control.”

Four embellishment penalties have been called on the ice through Sunday in these playoffs after 18 during the regular season according to Scouting the Refs , a website that tracks NHL officials (the NHL does not release the statistic).

Predators defenseman P.K. Subban was fined twice along with eight other players once in 2014-15 and Toronto Maple Leafs center Nazem Kadri was fined twice last season as 11 others were publicly announced as embellishers. This season, only three players – the Capitals’ Evgeny Kuznetsov and Arizona Coyotes’ Keith Yandle and Oliver Ekman-Larsson – received fines.

Bonino has never been cited, and Campbell said the Penguins forward was not on the list of known offenders. One of the heroes of Pittsburgh’s 2016 Cup run, he insisted he thought he was hit in the face, seeing on replay that Oshie’s stick pushed the plastic part of shoulder pad into his jaw to draw his reaction.

“I watched the replay and I was like, `Wow, there’s some backlash on this,’ I think when my history is that I’m a pretty honest guy and the last thing I want to do is embellish a call,” Bonino said. “When you get hit with anything, whatever, in the face, you’re not expecting it. I feel bad. I put the ref in a tough spot there, and you never want to do that.”

Even Capitals players didn’t blame referee Steve Kozari for making the call he thought he saw against Oshie, but center Lars Eller said the only way to prevent those situations is to make embellishment and diving subject to video review.

“He has to make a decision in a split-second and he’s not in a position to really see,” Eller said. “I think there needs to be some kind of review and there needs to be some kind of punishment for the other team that they’re going to feel because they got away with one there and it’s too important to get wrong.”

Campbell said adding video review for embellishment to coach’s challenges for offside and goaltender interference isn’t likely because the problem isn’t rampant and the league is concerned with slowing down games too much already.

Former referee Paul Stewart, who officiated in the NHL from 1986-2003, suggested authorizing the two linesmen to call embellishment along with the two referees just as they can for too many men on the ice or delay of game for puck over the glass.

More than anything, Stewart wants the responsibility to be on coaches.

“When they get that power play from the guy feigning having been tripped or slashed or whatever the case might be, they go back to the bench and they get these laurels and these kisses and all of this affection from their teammates and subconsciously they say, `Oh that worked,’ and they’ll do it again,” said Stewart, now the Eastern College Athletic Conference’s director of officiating. “If you said to a coach, `Your team has a tendency to dive and we have four examples or five and you’re sitting out,’ I’m going to tell you right now, they would stop it in half a heartbeat.”
