Utah Mammoth 2025-26 Season: The Year Utah Joined the Postseason
Salt Lake City had waited two seasons to see whether its new NHL team was a project or a contender. The Mammoth’s 2025-26 season delivered the answer. Utah clawed through a brutal early-winter slump, surged in January, and clinched the first playoff berth in franchise history. The run ended in a six-game war with Vegas, but the franchise left the spring with its identity firmly established.
The front office entered the summer convinced the roster needed one more scorer. On June 26, general manager Bill Armstrong sent defenseman Michael Kesselring and forward Josh Doan to Buffalo for winger JJ Peterka. The deal, outlined in NHL.com’s offseason roster review, added a 23-year-old coming off a 68-point season. Utah then locked him into a five-year contract.
Free agency brought experience. Nate Schmidt arrived with a fresh Stanley Cup ring from Florida, while Brandon Tanev added grit to the bottom six. Vitek Vanecek signed to back up Karel Vejmelka, and Connor Ingram was later moved to Edmonton. Matias Maccelli was traded to Toronto, and Nick Bjugstad left for St. Louis.
Armstrong did not hide his ambition. He called the group “probably the most competitive team we’ve had so far.” After a 38-31-13 finish the year before, the playoffs were the only acceptable measure. Andre Tourigny returned behind the bench with a mandate to push his young core over the line.
October looked like the breakthrough everyone expected. Utah stormed to an 8-3-0 record, highlighted by a 7-4 win in St. Louis. In late November, Logan Cooley scored four goals in a 5-1 thrashing of Vegas. That performance showed exactly how dangerous the 21-year-old center had become, and Utah had already rewarded him with an eight-year extension in October.
The good feelings did not last. The Mammoth went 9-16-3 across November and December, and the early cushion vanished. Even a 7-0 rout in Anaheim in early December, when Peterka piled up four points, failed to stop the bleeding. The season was drifting toward the familiar territory of near misses.
The calendar flip changed everything. On New Year’s Day, Dylan Guenther recorded his first NHL hat trick in a 7-2 win over the Islanders. That night launched a 10-4-1 January that pulled Utah back into the race. A 6-1 home win over Toronto on January 13 confirmed the team had found its legs again.
The defining moment came on January 21 against Philadelphia. Utah trailed 4-3 late and pulled Vejmelka for an extra attacker. Nick Schmaltz then got back to stop a Flyers breakaway on the empty net. Clayton Keller made the save count, burying a six-on-five equalizer that was Utah’s first extra-attacker goal in 131 games. Keller then won it in overtime, 5-4, and tossed his stick over the glass to a fan. That night stretched a point streak to eight games, and that stretch defined the season.
Armstrong refused to stand still. On March 4, Utah acquired defenseman MacKenzie Weegar from Calgary for Olli Maatta, Jonathan Castagna, and a 2026 second-round pick. A week later, Schmaltz signed an eight-year extension. Both moves signaled that the Mammoth’s 2025-26 season was about winning now, not someday.
Keller also returned from the Olympic break with a gold medal, earned in his first Olympics with Team USA. Utah went 7-6-2 in March, then caught fire in April. Back-to-back road routs in Seattle and Vancouver, 6-2 and 7-4, set the stage for the final push.
The breakthrough arrived on April 9. Utah beat Nashville 4-1 at home, and an Anaheim win over San Jose sealed the berth that same night. The Mammoth finished 43-33-6 with 92 points, fourth in the Central and first wild card in the West. Their 268 goals ranked 10th in the league, and the full game log lives on Hockey Reference.
Vegas, the Pacific Division champion, stood in the way. History arrived in Game 1, when Cooley scored with 11 seconds left in the first period. It was the first playoff goal in franchise history, even though Vegas won 4-2.
Game 2 carried the weight of a turning point. The score sat tied deep into the third period on the road. Then Cooley pounced on a rebound off a Guenther shot at 14:00 and slid it past Carter Hart. The 3-2 victory, detailed in the NHL.com Game 2 recap, was the first playoff win the franchise had ever recorded. Vejmelka made 19 saves for his first postseason win.
The Delta Center finally hosted playoff hockey on April 24. Weegar scored the first home playoff goal, and Utah raced to a 4-0 lead within 30 minutes. The Mammoth held on for a 4-2 win and a 2-1 series lead. For a market still learning its new team, that night felt like a coronation.
Game 4 began badly, as Vegas built a 3-0 lead early in the second period. Utah refused to fold. Schmaltz and Ian Cole scored 29 seconds apart, Michael Carcone tied it early in the third, and Mikhail Sergachev gave Utah a 4-3 lead. Brett Howden equalized, and Shea Theodore won it at 19:08 of overtime.
Game 5 in Las Vegas was crueler still. Carcone scored on a two-on-one with 7:18 left to give Utah a 4-3 lead. Utah was less than a minute from a 3-2 series edge. Then Pavel Dorofeyev completed a hat trick with 52.7 seconds remaining. Howden ended it with a short-handed goal in double overtime, as TSN’s Game 5 report recounted.
Those two overtime losses broke the series open. Back home for Game 6, Utah could not recover. Mitch Marner scored twice, Kailer Yamamoto answered with Utah’s lone goal, and Vegas closed it out 5-1.
Keller carried the offense and the locker room. The captain led the team with 88 points and a career-high 62 assists. He closed the season with a 10-game point streak while grieving the unexpected death of his father in November. That resilience earned him a nomination for the Bill Masterton Trophy.
Guenther became a true sniper, leading Utah with 40 goals. Schmaltz added 33 goals and 74 points, justifying the long-term commitment. Sergachev anchored the blue line with 59 points, and John Marino posted a team-best plus-42. Cooley scored 24 goals in only 54 games, a pace that hinted at stardom.
In goal, Vejmelka carried a heavy load with 38 wins across 64 appearances. Peterka contributed 25 goals while playing all 82 games. Lawson Crouse added 24 goals and matched Guenther with three playoff goals. Every season statistic is catalogued on Wikipedia’s season page.
The Mammoth’s 2025-26 season will be remembered as the year Utah hockey became real. A franchise still writing its first chapters played meaningful games in late April. Salt Lake City learned what a playoff crowd sounds like.
The series loss stung because it was so close. Two overtime defeats separated Utah from a potential upset of a division champion. Yet the experience mattered more than the result. Cooley, Guenther, and Keller now know the intensity of postseason hockey. Schmaltz is locked in for the long haul, and the blue line has a veteran spine.
Armstrong built this roster to contend, and it did. The Mammoth’s 2025-26 season set a new standard, one where a wild-card berth is the floor rather than the ceiling. Anything less than a return trip will now feel like a step backward. The next step is learning how to win those overtime games. For a fanbase that embraced the team from its first puck drop, this season delivered something priceless. It delivered proof that the Mammoth belong.
