SCOTTSDALE, Ariz. — Around the time the Coyotes were wasting a 5-on-3 power play in the second period of Thursday’s 4-2 win over Colorado, the cameras caught assistant coach Newell Brown frowning. The Coyotes’ power-play coach couldn’t remember what was frustrating him when asked on Friday. There was plenty of material from which to choose, however.

The Coyotes went 0-for-6 with the man advantage against Colorado, dropping the power play to 5-for-49 this season, which ranks dead last in the NHL at 10.2 percent. Arizona has scored a power play goal in just four of its 12 games this season while allowing four shorthanded goals.

“We’re doing a lot of good things but there’s another level that we can get to,” Brown said. “It’s not anything major. It’s little things: a couple feet here, a stick length there, one more pass for a good shot or shooting earlier than we did.

“Once we all get in sync, that’s when the results will come.”

It’s easy to forget that the Coyotes are operating with a number of new faces on their two power play units. Forwards Max Domi, Anthony Duclair and Jordan Martinook are all rookies, Mikkel Boedker is still learning his part-time role on the point and even defensemen Michael Stone and Connor Murphy could use more experience.

“There’s lot of stuff to learn,” coach Dave Tippett said.

Even so, Tippett agreed with Brown that there were lots of positives in Friday’s game.

“We created I think seven or eight quality chances off of it. It’s just not going in the net,” Tippett said. “If you get the chances, eventually the goals will come.”

With the New York Rangers in town on Saturday, it’s easy to remember a time when the Coyotes’ power play was among the more potent units in the NHL. That unit was led by defenseman Keith Yandle, who will make his return to Arizona on Saturday for the first time since the Coyotes dealt him to New York at last year’s trade deadline in the deal that brought Arizona forward Anthony Duclair.

“We played a lot together on the power play,” defenseman Oliver Ekman-Larsson said of Yandle. “We built that over the years. Now I’m trying to build something with Boeds on the blue line. Obviously, I miss a guy like Yandle. He moves the puck really good.”

Brown spent a portion of Friday reviewing film of the Colorado game with his two power play units at the Ice Den.

“In the previous games, we only had a couple power plays in each so there wasn’t a big sample size there, but last night was really good because we had a lot of opportunities and a lot of time in different situations so it was a good day to look at what we did well and what we could do better.”

Ekman-Larsson said the team’s zone entries have been clean and the team has been getting chances, but it needs to follow those chances.

“After we take the first shot we need to get the puck back a little bit quicker and be a little bit harder when we do that,” he said.

The Coyotes may never reach the levels they did when Yandle was quarterbacking the unit and it finished No. 7 overall the past two seasons, but Arizona can’t afford to let so many opportunities slip away when the team’s margin for error figures to be tight on most nights.

“The continuity isn’t there from shift to shift, whether it be the breakout or a faceoff or offensive zone play,” Brown said. “We’re still trying to connect all the dots.”
