TARRYTOWN, N.Y. — Mike Sullivan stood on the Rangers’ bench at Wednesday’s practice, stewing as his players went through special-teams work. At one point, he laid into the power-play group about its execution, then urged the penalty kill to make the opposing unit work harder.

The coach’s displeasure continued throughout the team’s full-ice reps.

“What the f— was that!?” he yelled at the top unit. Then, when the second unit had a try, he threw one arm up in apparent frustration.

“I just think we could’ve done a better job with our execution and our intensity,” Sullivan said afterward. “We’re trying to get better on both sides of the special teams. Our penalty kill has to pay more attention to detail. … There’s a tendency for the penalty kill to maybe give the power play a little bit of an opportunity to have success (in practice). We look at it differently: We want our penalty kill to compete extremely hard against our power play and push them to be at their very best.”

Sullivan, who spent the past 10 years coaching Pittsburgh before coming to New York, added that the tendency was, “not anything I haven’t been accustomed to in the past. … I just wanted to try to correct it.”

Sullivan’s frustration came two days after a 3-1 loss to Minnesota at Madison Square Garden. The Rangers are 0-4-0 at home this season and have scored only one goal in New York. Mika Zibanejad let some of his exasperation show after the Wild game, saying, “It’s frustrating for us. It’s frustrating for me” when asked about not converting on scoring chances.

In general, the Rangers’ underlying numbers this season have been encouraging, even if the goals haven’t followed. The Minnesota game, though, was a step back: The Wild dominated the first period and were, in Sullivan’s postgame words, quicker to and harder on pucks throughout the game.

Wednesday was the Rangers’ first practice since the Minnesota game. Along with yelling at his players during the special-teams work, Sullivan gathered them at center ice for a long talk at the end of the skate. Defenseman Adam Fox said Sullivan spoke to the team about “trying to get to the inside, trying to get some goals, try to score a bit more.”

“Nothing we didn’t know coming in: just responding well tomorrow pretty much,” Fox said ahead of Thursday’s matchup with the Sharks.

The power play will be an instrumental part of the Rangers’ quest to score more goals. The unit ranks No. 26 in the league with a 15 percent success rate and has only three power-play goals on the year, though it scored an additional one that came moments after a two-minute man-advantage ended in Montreal. Fox, Zibanejad and Artemi Panarin have been mainstays on the top unit for years, but captain J.T. Miller and Alexis Lafrenière are both newer additions. Miller has been on the top unit since New York acquired him in January, and Lafrenière is getting his first extended look this season. Fox said everyone on the unit is getting more familiar with each other’s games.

For Lafrenière, the 2020 No. 1 draft pick, more power-play time hasn’t yielded more scoring output. He has only two points on the year, neither of which came on the power play. Asked about him and fellow youngster Will Cuylle — who is on the second unit — Sullivan said Wednesday that he thinks “there’s another level to their game.” He wants both to skate to the net more and get to the interior of the ice.

Fox has liked the looks the power play has produced, even if they haven’t yielded great results. Wild goalie Filip Gustavsson made a shoulder save on a Zibanejad look from the slot Monday, and Miller missed the net on a redirect attempt.

“We want to be able to score goals — that’s the name of the game — but you’ve got to get looks to do that,” he said.

“They’ve had a lot of zone time in the power plays that they’ve had and they’ve generated a fair amount of scoring chances,” Sullivan added. “The next step is we’ve got to put it in the net.”

Sullivan listed many ways they can do that: Have better net-front presence, block the goalie’s eyes and don’t pass up as many shots.

“You can create offense off the power play a number of different ways, some of them highlight-reel goals that you see on ESPN,” Sullivan said. “But a lot of them, there’s a rebound that lays somewhere, and it’s a broken play. Now, guys create off of that. We’re trying to create a power play that has the ability to do both.”

The Rangers seem to have been trying to create power-play looks for players such as Zibanejad and Miller in the slot. Fox said the unit has emphasized this more this year, and he thought it’s generated strong chances.

As for Sullivan’s fire at practice, Fox understood where his coach was coming from.

“We got better (against Minnesota) as it went along, but you can’t come out with a first period like that against a good team,” he said. “We understand that, so I think just knowing that last game wasn’t good enough and (overall) we’ve done some good things, but not to get complacent just because we’ve done some good things for a few games.”
