Where did all the usual suspects go?

History was made in the NHL this season, but not the kind that its most storied U.S. franchises wanted. The 2025 Stanley Cup playoffs mark the first time that the Boston Bruins, Chicago Blackhawks, Detroit Red Wings and New York Rangers have all missed the cut in the same postseason:

• Chicago's in a rebuild

• Detroit was supposed to finally emerge from one but missed the playoffs for the ninth straight season, despite an in-season coaching change -- the sixth season without a postseason berth under GM Steve Yzerman

• The Bruins fired their coach 20 games into the season, only to eventually ship out a number of veteran players at the trade deadline while missing the playoffs for the first time in nine seasons

• The Rangers went from the league's best record to finishing eight points out of the playoffs, and could see major changes in the offseason

The New York Islanders, Nashville Predators and Vancouver Canucks were all 2024 playoff teams that didn't make it back this season. Sidney Crosby and the Pittsburgh Penguins missed the playoffs for the third straight season.

So the 2025 postseason won't have a number of glamour franchises and superstar players. But that just creates room in the spotlight for others to emerge.

Can the Panthers repeat?

The Stanley Cup champion Panthers finished third in the Atlantic Division with 98 points, down significantly from their 110-point season a year ago. Injuries were a factor: Captain Aleksander Barkov was limited to 67 games, and spiritual leader Matthew Tkachuk played only 52 games and hasn't been in a game since the 4 Nations Face-Off in February. Top defenseman Aaron Ekblad was also limited to 56 games after being suspended 20 games for violating the terms of the NHL/NHLPA performance-enhancing substances program. The earliest he can return is Game 3 of the Panthers' Battle of Florida first-round series against the Tampa Bay Lightning.

All of this is to say that we haven't really seen what this version of the Panthers is going to look like with all systems go. There are some constants from last year's Cup-winning roster: Sam Reinhart was brilliant again, with 81 points in 79 games and could win the Selke Trophy as the league's best defensive forward. Clutch playoff performers Carter Verhaeghe and Sam Bennett, as well as defensive rock Gustav Forsling, are back for another run.

But it's a different supporting cast. Defensemen Brandon Montour and Oliver Ekman-Larsson, and forwards Vladimir Tarasenko and Kevin Stenlund moved on after last season. Florida made two blockbuster additions to bolster their group before the trade deadline, acquiring defenseman Seth Jones from the Blackhawks and Bruins captain Brad Marchand.

The Panthers certainly have the players for a third straight trip to the Stanley Cup Final and a repeat as champions. It's just a matter of whether they all fit as snugly as they have previously under head coach Paul Maurice. If nothing else, the first round should give us our first look at Marchand and Tkachuk both yapping on the same team. Humanity might never be the same.

If they win the Battle of Florida, can the Lightning win the Cup?

The Lightning finished second in the Atlantic with around the same record as last season, but they feel like a much more dangerous team.

Tampa Bay led the NHL in goals per game, powered by winger Nikita Kucherov, who was the league's top point scorer this season (121) while setting up Brayden Point (42 goals) and Jake Guentzel (41 goals) for dominant seasons. Winger Brandon Hagel had 90 points in 81 games, and was one of the NHL's best all-around players; ditto center Anthony Cirelli (27 goals), who's in the conversation for the league's top defensive center this season.

On the blue line, former Norris Trophy winner Victor Hedman led his teammates in average ice time by nearly two minutes.

But it's the reemergence of star goalie Andrei Vasilevskiy that has bolstered the Bolts' Stanley Cup chances. He had his best season since 2020-21, and was recently named the league's top goalie in a survey of his peers. If Vasilevskiy can carry that over to the postseason, where he always has been at his best, the Lightning could be in business.

Tampa Bay hasn't escaped the first round since losing in the 2022 Stanley Cup Final to Colorado, which followed consecutive Cup wins for the Lightning. Perhaps seeking to recapture that magic, GM Julien BriseBois reacquired two players from their title reign: defenseman Ryan McDonagh, who has been outstanding this season after being traded from Nashville; and center Yanni Gourde, a trade- deadline pickup from Seattle who has fit right back in with the Lightning.

If they can get past their archrivals -- admittedly, a big "if" -- the potential for another boat parade in the bay isn't out of the question.

What can we expect from the Battle of Ontario?

The NHL wild-card format exists to maximize the potential for rivals to meet in the postseason, and it worked like a charm in the Eastern Conference: Not only is there another Battle of Florida, but the Battle of Ontario has been reignited between the Toronto Maple Leafs and Ottawa Senators, the latter of whom finished in the first wild-card spot to end a seven-year playoff drought.

These rivals met four times between 2000 and 2004, with Toronto winning each time. We don't want to say Senators fans are salivating at the chance to take down the Atlantic Division-leading Leafs, but the streets of Ottawa are currently flooded.

The Maple Leafs are still on their quixotic mission to win the Stanley Cup for the first time since 1967. As usual, there are reasons to believe. Winger Mitch Marner, an unrestricted free agent this summer, had 100 points in 80 games. Forwards William Nylander (45 goals) and Auston Matthews (77 points in 66 games) were dominant, while pending free agent John Tavares regained his point-per-game form.

Toronto's hopes rest on the pads of goalies Joseph Woll and Anthony Stolarz, who led the Leafs to the fourth-best team save percentage in the NHL in the regular season. But questions about their lack of playoff experience (a combined eight games) and ability to remain healthy linger.

The Senators' playoff berth marks the first time Brady Tkachuk has participated in an NHL postseason -- other than being a spectator at his brother's games. He's the driving force behind an Ottawa team with strong young talents in forward Tim Stutzle (76 points) and defenseman Jake Sanderson (55 points).

But the key is goaltender Linus Ullmark, acquired from the Bruins last summer. He had a solid regular season but has a career postseason record of 3-6 with a .887 save percentage, all with Boston. He has something to prove.

Alex Ovechkin broke Wayne Gretzky's goals record. Could another Stanley Cup be his next accomplishment?

When Ovechkin re-signed with the Capitals, there was a promise made by Washington to remain a playoff contender around him as he chased down Gretzky so Ovechkin wasn't just compiling goals in meaningless games. No one could have predicted the Capitals would retool to the point where they finished atop the Eastern Conference.

The Capitals were the second-best team offensively and finished in the top 10 defensively this season. Offseason bets on players such as forward Pierre-Luc Dubois, defenseman Jakob Chychrun and goalie Logan Thompson paid off, while homegrown talents Aliaksei Protas and Connor McMichael thrived -- as did star defenseman John Carlson, who had his best season in years.

But the Capitals are a mystery in the playoffs. When they play coach Spencer Carbery's system to perfection, they can beat anyone in the league. But beyond Ovechkin, there isn't another established star difference-maker in the lineup. That has made some observers skeptical that their regular-season success could transfer over the playoffs. But what an incredible cap to an all-time season it would be if Ovechkin raised his second Stanley Cup -- and his first as the NHL's goal-scoring GOAT.

Are the Devils toast without Jack Hughes?

New Jersey was well on its way to returning to the playoffs when it lost leading scorer and No. 1 center Hughes to a shoulder injury, which is expected to keep him out until next season's training camp.

Hughes had 70 points in 62 games. Since Hughes went out, the Devils are 9-10-1 for a .475 points percentage, 23rd in the NHL in that span. They were also without top defenseman Dougie Hamilton, who was injured one game after Hughes went out. Hamilton returned to the lineup in their regular-season finale.

It's hard to conceive that the Devils could win the conference without Hughes, but players such as center Nico Hischier and winger Jesper Bratt stepped up significantly in his absence. Whether the Devils make any noise in the playoffs comes down to their goaltending, and specifically Jacob Markstrom, who has the ability to steal games but hasn't consistently shown this season -- much like the team in front of him.

Is this the year Carolina breaks through for a championship run?

For years, the Hurricanes have fallen just short in the playoffs, losing in the conference finals twice and the second round three times under coach Rod Brind'amour. Usually the culprit has been their inability to get a key goal at a key time in a series.

Last season, they traded for Jake Guentzel, a proven playoff performer, but Carolina stalled out in the second round and Guentzel walked as a free agent. This season, they made a blockbuster trade with Colorado that saw the Hurricanes ship leading scorer Martin Necas to the Avs for Mikko Rantanen ... only to then trade Rantanen to Dallas before the deadline, after the star winger declined to sign a contract extension in Raleigh. Carolina acquired 21-year-old forward Logan Stankoven in the deal, a talented scorer but not one yet on the level of Rantanen or Guentzel.

So the Hurricanes are right back where they've been: a grinding, aggressive puck possession team with an offense and defense both in the top 10 and the best penalty kill in the league. They have some offensive pop from players such as Sebastian Aho and Seth Jarvis, but it's saying something that Necas is still their third-leading scorer. They also have goaltenders in Pyotr Kochetkov and Frederik Andersen that led the Canes to finishing 23rd in team save percentage (.889).

Yet a bounce here, a break there and a key goal in a key moment, and no one would be surprised to see Brind'Amour's team break through in the East. It just seems a little less possible after the Rantanen revolving door.

Is Dallas vs. Colorado peak postseason drama?

With due respect to the geographic rivalry series in the Eastern Conference, no series has more compelling storylines than the Stars vs. the Avalanche in a matchup of Central Division rivals.

Consider that the Stars were picked by many to win the Stanley Cup this season, while the Avalanche have aggressively retooled their team from the crease out after losing to Dallas in the second round last season, seeking another Cup win after raising it in 2022.

Consider that the Avalanche decided Rantanen was not in their long-term plans, traded him to Carolina and then watched as the Hurricanes traded him to Dallas, where he signed an eight-year, $96 million deal. Rantanen has forged a reputation as one of the NHL's top postseason scorers. He'd like nothing more than to remind the Avalanche why that is.

Consider that the Stars are taking on one of the best teams in the NHL with two major injury concerns. Top defenseman Miro Heiskanen hasn't played since Jan. 28 because of a knee injury. There has been speculation out of Dallas that he could sit out this series, but GM Jim Nill seemed to indicate recently that there was a chance he could return in the first round. Meanwhile, star winger Jason Robertson sustained a lower-body injury in the Stars' regular-season finale. His status was unclear for the Avalanche series. According to Betalytics, Colorado's chances to win the series increase by over two percentage points if Robertson can't play;

Finally, consider that Colorado captain Gabriel Landeskog is in the midst of one of the NHL's greatest comebacks in recent memory. His most recent game in the league was June 26, 2022, when he and the Avalanche won the Stanley Cup. He sat out the following season after right knee surgery. He underwent cartilage transplant surgery and sat out 2023-24 and most of this season. Landeskog had been skating with the Avalanche and then returned to competitive play with the AHL Colorado Eagles. This incredible comeback journey could see him return to NHL action in Game 1 against Dallas.

This matchup has enough storylines for 10 series. It's also a battle that could easily produce this season's eventual Stanley Cup winner.

Besides Rantanen, who are the other familiar faces in new places who could affect the playoffs?

As mentioned, the Avalanche aggressively added to their group all season, including a total makeover of their goaltending that saw former Sharks goalie Mackenzie Blackwood take over the crease. They also added forwards Brock Nelson (Islanders) and Charlie Coyle (Bruins), as well as defensemen Ryan Lindgren (Rangers) and former Avalanche player Erik Johnson (Flyers) before the trade deadline.

In addition to trading Coyle and Marchand, the Bruins also sent veteran defenseman Brandon Carlo to the Maple Leafs.

Ottawa bolstered its team for now and in the future by acquiring center Dylan Cozens from Buffalo. Tampa Bay added forward Oliver Bjorkstrand in the trade with Seattle that also got them Gourde.

Which rookies could make an impact in the playoffs?

If the Montreal Canadiens are going to upset the Washington Capitals, two rookies are going to have to make a major impact. Defenseman Lane Hutson is the favorite to win the Calder Trophy as rookie of the year after 66 points in 82 games, leading all first-year players. Forward Ivan Demidov, a dynamic offensive star in the KHL, signed with Montreal late in the season and made an immediate impact. He's one to watch.

Among the other rookies who'll be counted on in the playoffs are Stankoven, who had 37 points in 77 games with Dallas and Carolina; forward Zack Bolduc (36 points) of the St. Louis Blues; forward Jackson Blake (34 points) of the Hurricanes; forward Mackie Samoskevich (31 points) of the Panthers; and center Mavrik Bourque (25 points) of the Stars.

Can Winnipeg break the Presidents' Trophy curse?

The Jets finished with 116 points to earn the No. 1 overall seed in the NHL and with it the Presidents' Trophy. Congratulations, and we're sorry.

The Presidents' Trophy curse is well-known hockey lore among players and fans. There have been 39 winners of the hardware since it was introduced in 1985-86. Only eight teams that finished first overall went on to win the Stanley Cup. For context, seven Presidents' Trophy winners lost in the opening round. It has only gotten worse since the NHL moved to a wild-card format in 2013-14: No Presidents' Trophy winner has gone on to play for the Stanley Cup, let alone win it, while two teams (Tampa Bay in 2019 and Boston in 2023) lost in the opening round.

The Jets are on a mission after two straight seasons of losing in the first round in five games. They talked down regular-season accomplishment all season, with a focus on the postseason. Winnipeg had the fourth-best offense in the NHL, powered by the league's best power play. More importantly, they had the NHL's best goaltender in Connor Hellebuyck, last year's Vezina Trophy winner who finished atop the league in both traditional stats and analytics. Like the rest of his team, Hellebuyck wants to flip the script on his own underwhelming numbers from last postseason.

The Jets face a Blues team that made the playoffs after a torrid 12-game winning streak in March, as part of an 18-3-0 run. The Blues fired coach Drew Bannister after 22 games, when Jim Montgomery became available after Boston fired him. After the 4 Nations Face-Off, St. Louis finally found its stride under Montgomery: first in 5-on-5 offense and second in defense during the winning streak.

St. Louis won't be an easy out for Winnipeg. As Blues goalie Jordan Binnington showed at 4 Nations for Canada, he can rise to meet the moment.

Is the fourth time the charm for the Los Angeles Kings?

The Kings had an outstanding regular season under new coach Jim Hiller, who guided L.A. to a .648 points percentage, the second highest in franchise history. They found a goalie in Darcy Kuemper, who had some of the best numbers of his career in back of the second-best defensive team in the NHL.

And what did all of this earn the Kings? A fourth straight first-round matchup against Connor McDavid and Leon Draisaitl.

The Kings lost in seven games in 2022, six games in 2023 and five games last season. Obviously, L.A. fans would like that trend to end. If the Kings finally get past the Oilers, their combination of defensive dominance and offensively opportunistic veterans such as Adrian Kempe (35 goals), Anze Kopitar (67 points) and Kevin Fiala (35 goals) could be a force in the West.

Will Connor McDavid and Leon Draisaitl finish the story?

The Edmonton Oilers came within one victory from hoisting the Stanley Cup last season, rallying from a 3-0 deficit to force a Game 7 before losing to the Panthers.

This season has had its challenges for Edmonton. Evander Kane sat out the regular season because of knee injury. McDavid and Draisaitl both sat out because of injuries, but Draisaitl was the league's top goal scorer with 52 in 71 games. Steady defenseman Mattias Ekholm will sit out the Kings series because of an injury. The Oilers played inconsistent defense in front of goaltending that ranked 16th in team save percentage.

If the Oilers are going to get back to the Stanley Cup Final, they'll need their stars to carry them, their supporting cast to step up and goalies Stuart Skinner and Calvin Pickard to play well enough not to cost Edmonton a series. A lot broke the Oilers' way last season. The road's even tougher in the West this postseason.

Which team is the X factor in the 2025 playoffs?

The Vegas Golden Knights' ceiling might be the Stanley Cup, which they won for the first and only time in 2023. But it has been difficult to get a handle on how good they can be given some of their lineup absences: Only five Vegas players played over 80 games this season. But the Knights made it work: They finished third in team defense, fifth in offense and first in the Pacific Division.

There are difference-makers all over the lineup. Jack Eichel had a career season, with 93 points in 77 games. Pavel Dorofeyev had a breakout with 35 goals, with Tomas Hertl -- always a postseason standout -- right behind him, with 32 goals. Mark Stone played 66 games but had 67 points in them. Vegas has as solid a defense corps as you'll find in the West, in front of goalie Adin Hill, who overcame a slow start to have a solid season.

The Knights draw a Minnesota team in the first round that clinched a playoff spot in their last game of the season, and are riding some good vibes now that Kirill Kaprizov and Joel Eriksson Ek are both healthy. There's always a chance that Marc-Andre Fleury helps author an upset against his former team in the last playoff run of his career. But more likely, it'll be Vegas moving on -- it's just a question of how long their run will last.

So who wins the Cup?

There's no juggernaut ready to slice through the playoffs to the Cup Final. A handful of teams have a rightful claim to the throne and none would be surprising should they ascend to it.

According to ESPN BET, the Avalanche are the favorites to win it all, followed by the Panthers, Hurricanes, Golden Knights, Oilers and Jets.

The Leafs have the longest Stanley Cup drought, having not won since 1967. The Oilers actually have the second longest, having last won the Cup in 1990.

There are 10 current NHL teams that have yet to win the Stanley Cup. Three of them are in this playoff bracket: Wild, Senators and Jets.

Will it be a team that has never hoisted the Cup before? Will it be a team that has been on the precipice of a championship like Carolina and Dallas? Will it be a recent winner, cycling back to another title? Your guess is as good as ours.

Enjoy the Stanley Cup playoffs, everyone -- the best postseason in sports.
