LAS VEGAS — Once again, the Anaheim Ducks were involved in a seven-goal hockey game.

Only this time, they needed some help to get to the lucky number.

A giveaway at the blue line by Shea Theodore wound up making a hero out of Jacob Trouba as his goal with 32 seconds remaining in overtime gave the Ducks a 4-3 win over the Golden Knights Saturday at T-Mobile Arena to keep Anaheim atop the Pacific Division.

“Honestly, it’s a game we probably should have won,” Knights coach Bruce Cassidy said, given his team had three great chances in the extra period to cap a comeback that began in the third period with goals from Pavel Dorofeyev and Kaedan Korczak and eventually force OT.

So if you’re a Golden Knights fan, which would you like first, the good news or the bad news?

Most of you probably want the bad news first, so here goes.

The Knights once again had a terrible second period that would lead to yet another loss at home. The much-improved Ducks won battles along the boards and got a pair of goals from Leo Carlsson to take a 3-1 lead going into the third period.

Want more bad news? William Karlsson left the game after the first period with a lower-body injury and did not return. His line was responsible for the first Vegas goal as he set up Brett Howden in front of Petr Mrazek and Howden beat Mrazek for his third of the season.

Coach Bruce Cassidy said following the game that Karlsson’s status for Monday against Florida remains to be determined.

The good news? The Knights remembered how to score on the power play. Dorofeyev beat Mrazek from close range to cut it to 3-2 in the third period while Carlsson was in the penalty box for high-sticking. It was just the third power play goal registered by Vegas in 26 attempts since Oct 18 when Mark Stone was injured against Calgary and has since gone on LTIR.

Cassidy also shook up his D pairs, playing Korczak with Noah Hanifin and Zach Whitecloud with Jeremy Lauzon. The move paid off as Korczak tied the game with a shot from the slot with 5:07 remaining in regulation.

But the Knights are still struggling to put together 60 minutes. The 1-0 win over Detroit last Tuesday is as close as they’ve come on this six-game homestand which has seen Vegas go 1-2-1 with games still to come against the defending Stanley Cup champion Panthers Monday and the New York Islanders Thursday.

The second-period lulls are alarming. The giveaways in their own end are hurting. And despite Dorofeyev’s goal, Vegas still struggles to enter the opposition’s zone cleanly when it has the man advantage.

Yet, give the Knights credit for not allowing the Ducks to expand their lead like they did in their wins over Dallas and Florida which saw Anaheim register seven goals in each contest.

But it’s hard to win when you’re not getting contributions throughout the lineup. Reilly Smith has just one goal this season and hasn’t scored since his OT winner in San Jose Oct. 9. Brandon Saad has yet to score in 13 games. Same for Colton Sissons, Brayden McNabb, Jeremy Lauzon, Keegan Kolesar along with Theodore and Whitecloud.

That’s a lot of zeroes and it’s not conducive to winning hockey. And while it is more important for your defensemen to prevent goals rather than score them, getting contributions offensively would certainly help.

Which is why you may see Korczak remain with Hanifin as a D pair on Monday.
