SUNRISE, Fla. — Bruce Cassidy’s Vegas Golden Knights lost eight of 10 games going into the All-Star break after leading the Pacific Division at the midway point of the NHL season.

They’re still safely in a playoff spot in the Western Conference, but they can’t keep it up.

“We’re still in a good position – that’s the way we look at it,” Cassidy said. “There’s not too many teams that can cruise home the last 30 games in this league, and we’re certainly not one of them.”

Cassidy’s old team, the Boston Bruins, probably could. They’re atop the NHL and running away with the Atlantic Division.

With 39 wins and 83 points through 51 games, Boston is on pace to break the record for the best regular season in NHL history. The Carolina Hurricanes, who beat Boston in seven games in the first round last year, are next in the standings at 76 points.

“Top to bottom, there’s no weaknesses,” Carolina Coach Rod Brind’Amour said of the Bruins.

The Bruins are in a class of their own, but the playoff races behind them in the East and West should be hot down the stretch with roughly 30 games to go before the chase for the Stanley Cup begins.

METROPOLITAN DIVISION

The Hurricanes rode a seven-game winning streak into the break, putting some fear into the Bruins in the race for the Presidents’ Trophy and home-ice advantage through the postseason. Winger Max Pacioretty re-tearing his right Achilles tendon five games into his return didn’t slow them down, and if their goaltending holds up, Carolina stands a good chance of reaching the East final.

“This team, it’s a special group of guys,” said Brind’Amour, who captained Carolina to the Cup in 2006 and is in his fifth year as coach. “We kind of show that nightly. It’s just very consistent, and they take their job real serious. They do it right.”

The second-place New Jersey Devils are contending for the first time since 2018. Bottoming out the next season helped them win the lottery for No. 1 pick Jack Hughes, a two-time All-Star who has them winning ahead of schedule.

“Much better than being out of the mix,” Hughes said. “We’re really excited because it’s going to be a lot of important hockey, and it’s going to be really competitive and we’re really pumped to be where we are.”

They’re followed by the New York Rangers, Washington Capitals, Pittsburgh Penguins and New York Islanders. All three New York-area teams could make the playoffs, which was the expectation for the Rangers after reaching the East final last year.

“I think the run last year really taught us a few things and stuff that we obviously could build on for the rest of this year,” 2021 Norris-Trophy winning defenseman Adam Fox said.

ATLANTIC

The Rangers lost to the Lightning in six games last spring, when two-time champion Tampa Bay reached the Stanley Cup Final for the third consecutive season before losing to the Colorado Avalanche.

The Lightning are almost certain to face the Toronto Maple Leafs – who haven’t won a playoff series since the NHL salary cap era began in 2005 – in the first round of the playoffs and remain a threat to the Bruins.

But Boston has separated itself despite starting the season without top left winger Brad Marchand and No. 1 defenseman Charlie McAvoy. The Bruins have lost only 12 games under new coach Jim Montgomery.

“You just keep winning,” said All-Star right winger David Pastrnak, who’s tied for third in the league in scoring. “Every single line and every single guy is going and it obviously builds our confidence. It’s funny sometimes what confidence can do in hockey.”

The Islanders should have some more confidence after acquiring 30-goal scorer Bo Horvat from Vancouver, but still need to make up ground to get in.

CENTRAL

Defending champion Colorado climbed in the standings – winning seven of eight going into the break despite an injury-riddled first half of the season. Captain Gabriel Landeskog still has not made his season debut since undergoing knee surgery. It would be foolish to bet against the Avs coming out of the West again.

“It’s up to us: We control our own fate,” All-Star center Nathan MacKinnon said. “We need to definitely keep playing the way we were before the break. No matter who’s in the lineup, we were playing well, playing hard, so it would definitely help with healthy bodies.”

They still trail the Dallas Stars, Winnipeg Jets and Minnesota Wild in the Central, and the Nashville Predators are on their heels. Only the Stars and Jets are essentially guaranteed a spot.

“Every point, you grind for it,” Stars leading scorer Jason Robertson said. “Every point’s going to be a dog fight, so it’s going to be a fun 30 games down the stretch.”

PACIFIC

Undisputed MVP favorite Connor McDavid and the Edmonton Oilers, who were swept by Colorado in the West final, have a little bit of catching up to do in the Pacific Division.

The top spot is held by the Seattle Kraken, who surprisingly are on pace to make the playoffs in their second season but still need to fend off the Kings and the Golden Knights.

Edmonton – and the Battle of Alberta rival Calgary Flames – have the talent to not only get in but make a run. McDavid leads the league with 41 goals and 92 points, 16 more than No. 2 scorer and teammate Leon Draisaitl, and is producing unlike anyone since Hall of Famer Mario Lemieux in the mid-1990s.

Now he’ll try to carry the Oilers into the playoffs and beyond.

“It hasn’t been easy at all for our group. We’ve kind of had to battle for everything that we’ve got,” McDavid said. “We’ve always been a second-half team for whatever reason. Even since my first year, we’ve always been better in the second half, so we’ll definitely look to continue that. That being said, we’re not going to hang our hat on that and expect that to carry us to the playoffs. There’s a lot of work to be done.”
