William Karlsson's Extension, Explained: How the New Deal Stacks on the Old One, and Which Original Misfits Are Left

by Ryan Rose

What Happened: The Deal, Line by Line

On Wednesday, Sept. 30, 2026, the Vegas Golden Knights signed center William Karlsson to a two-year contract extension. KTNV 13 Action News reported the deal pays $6.75 million per year. FOX5 and other outlets put the total value at $13.5 million. Karlsson is 33 years old and a native of Marsta, Sweden.

Here is the part that trips people up. The extension is not a new contract that replaces the old one. Karlsson still has one season left on the eight-year, $47.2 million deal he signed in 2019. That deal carries a $5.9 million average annual value, and its last season is 2026-27, the one that just started. The new extension kicks in after that, for 2027-28 and 2028-29.

So the simple timeline looks like this:

2026-27 (this season): final year of the 2019 contract, $5.9 million cap hit.
2027-28: first year of the extension, $6.75 million cap hit.
2028-29: second and final year of the extension, $6.75 million cap hit.

Add those up and the team has about $19.4 million in cap hits committed to Karlsson over the next three seasons. The raise on the new deal is $850,000 per year compared with his current cap hit. That is a modest bump for a player who has been one of the most steady pieces of the franchise for nine years.

General manager Kelly McCrimmon explained the thinking to the Las Vegas Review-Journal. "He's tremendously valuable to our team," McCrimmon said. "He's such a good skater, such an intelligent player. I just think that he's always going to provide great utility to our team."

The timing also matters. The Karlsson deal came 18 days after the team signed captain Mark Stone to his own two-year extension on Sept. 12. McCrimmon tied the two moves together. "I just think it gives continuity to our team," he told the Review-Journal. "The other players on your team know that you're committed to try and keep the top players in the organization here and continue to try to win."

Cap Hit, Salary and Term in Plain English

Hockey contracts come with their own language, so here is a quick guide. The "cap hit" is the number that counts against the team's salary cap each season. It is the total value of the contract divided by the number of years. For Karlsson's extension, that is $13.5 million divided by two years, or $6.75 million per season.

The cap hit is not always the same as the paycheck in a given year. Teams can move salary and bonuses around inside a deal, but the cap hit stays flat. The public reports on this extension focus on the cap hit and the total value, so those are the two numbers that matter for fans.

"Term" just means how many years the deal runs. A short term, like two years, lowers the risk for the team as a player gets into his mid-30s. It also gives the player a raise and some security now. For a center coming off an injury-shortened season, a two-year term is a middle ground that works for both sides.

One more thing that confuses people: an extension signed now does not change this season's numbers at all. Karlsson's $5.9 million cap hit for 2026-27 stays exactly where it was. The new $6.75 million figure only shows up on the books starting next fall.

Why It Matters to Las Vegas Residents

For a lot of Las Vegas families, the Golden Knights are the first major pro team they ever had a real connection to. The 2017 team showed up in a city that was hurting after the Oct. 1 shooting, and those first players became part of how the valley healed and came together. Karlsson was one of them. Keeping him here keeps a living link to that season.

There is also a practical side. Fans spend real money on this team. Season tickets, jerseys, watch parties and game-night dinners all add up. When a team keeps its core players, fans can buy that No. 71 jersey with some confidence it will still mean something in two years. That is not a small thing for parents shopping for a birthday or holiday gift.

Then there is cost certainty. Daily Faceoff wrote that the deal gives Vegas more cost certainty and projected about $14.7 million in cap space for the 2027-28 season. In plain terms, the front office now knows what its center group will cost when the extension starts. That makes it easier to plan the rest of the roster, whether that means re-signing current players or chasing new ones.

Finally, this is about the kind of player Karlsson is. He is not the loudest guy on the ice. He kills penalties, he wins puck battles, and he shows up in the playoffs. The Review-Journal noted that he leads all active NHL skaters with a plus-55 rating in the postseason. That kind of quiet, reliable play is what helps a team keep its spot as a contender year after year, and contending teams keep T-Mobile Arena full on weeknights.

Background and History: From Side Deal to Franchise Record

Karlsson's path to Vegas is one of the best stories in the team's history. The Anaheim Ducks drafted him in the second round, 53rd overall, in 2011. Anaheim traded him to the Columbus Blue Jackets in March 2015. When the 2017 expansion draft came around, Columbus did not want to lose certain other players. So the Blue Jackets made a side deal. They sent Vegas a 2017 first-round pick, a 2019 second-round pick and the contract of David Clarkson. In return, Vegas agreed to select Karlsson.

At the time, Karlsson was seen as a depth player. Then he scored 43 goals in the expansion year. That is still the franchise record for goals in a single season, and it was his career high. He finished with 78 points that season. He also won the Lady Byng Memorial Trophy in 2018, which the NHL gives for sportsmanship and gentlemanly conduct paired with a high level of play.

Longtime fans remember one goal more than the rest. On March 31, 2018, Karlsson scored a shorthanded goal between his legs that clinched the Pacific Division title. That goal still gets replayed on the big screen.

After that breakout year, Vegas signed him to a one-year, $5.25 million bridge deal in August 2018. In June 2019, the team gave him the eight-year, $47.2 million contract that ends this season. In his first season on the bridge deal, he scored 24 goals and 56 points in 82 games. He spent the years that followed turning into one of the best two-way centers in the league. He has also played for Sweden on the international stage, winning gold at the 2017 IIHF World Championship and bronze at the 2025 tournament, according to FOX5.

Here is where he stands in the Golden Knights record book, based on figures reported by FOX5 and the Review-Journal:

Most goals in one season: 43, in 2017-18 (first all-time).
Career goals with Vegas: second all-time.
Career points with Vegas: 403, second all-time.
Shorthanded goals: 15, first all-time.
Shorthanded points: 26, first all-time.
Plus-minus: plus-128, second all-time.
Takeaways: 382, second all-time.

His playoff résumé might be even better. He has played 121 postseason games. In the 2023 run to the Stanley Cup, he played all 22 games and scored 11 goals and 17 points.

Which Original Misfits Are Still in Vegas?

The "Original Misfits" is the name fans gave the players Vegas picked up in the 2017 expansion draft. Other teams left them unprotected, and they turned that into a run to the Stanley Cup Final in year one. Nine seasons later, most of that group has moved on.

KTNV reports that Karlsson is one of just three Original Misfits still on the roster. The other two are defensemen Brayden McNabb and Shea Theodore. According to the Review-Journal, those three also top the franchise list for regular-season games played:

Brayden McNabb: 648 games.
Shea Theodore: 582 games.
William Karlsson: 570 games.

That is a short list, and it will only get shorter over time. With Karlsson now signed through 2028-29, at least one Misfit is locked in to see the team well into its second decade.

What Happens Next

The first thing to watch is health. Last season was rough for Karlsson. According to the Review-Journal, a hamstring injury that had bothered him for two years cost him 68 games. He played just 14 regular-season games and scored seven points. He came back for the second round of the playoffs and centered a line with Brett Howden and Mitch Marner as Vegas reached the Stanley Cup Final for the third time in nine years. Vegas led the Carolina Hurricanes 2-1 in that series before losing the last three games, and Karlsson broke his wrist in Game 5.

McCrimmon said the time away showed the team what it was missing. "He missed a lot of time last year, which, to be honest, made us realize how valuable he is to our team," he told the Review-Journal. "He almost shows up more when he's not playing than when he is. But when he joined our team back in the playoffs, he was terrific."

The second thing to watch is the rest of the roster. With Stone and Karlsson both done, the Review-Journal reported that Vegas has four pending unrestricted free agents left after this season: forwards Victor Olofsson and Nic Dowd, defenseman Parker Wotherspoon and goaltender Carter Hart. How those four play this season will shape the next round of contract news.

Season X is already underway. Karlsson's new deal does not change anything about this season's paycheck. It just means fans do not have to spend the year wondering whether this is his last one in Vegas.

Ryan's Take

I like this deal for the same reason I like a well-built home in an established neighborhood. It is not flashy. It is reliable, and it holds its value. The Golden Knights paid a fair price to keep someone who knows the system, kills penalties and shows up in May and June. That is a smart long-term move, not a headline grab.

I also think about what Vegas hockey means for the people who live here. When I talk with families moving to the valley, a lot of them ask about the Golden Knights before they ask about anything else. Season X, a deep playoff team, and players who stick around for a decade all help make Las Vegas feel like a real hometown and not just a place you pass through. That matters when someone is deciding whether to put down roots in Summerlin, Henderson or the southwest valley. Stability on the ice and stability in a neighborhood have a lot in common. People want to know the things they care about will still be there in a few years.

What You Can Do

If you want to see one of the last Original Misfits play in person, this is a good season to do it. Check the team schedule at VegasGoldenKnights.com for home games at T-Mobile Arena, and look for weeknight games if you want a lower-cost way to bring the kids. Every game also airs on X 107.9 in English and 105.7 Maxima in Spanish, so you can follow along from the car.

If you have young players at home, Karlsson is a great player for them to watch. Point out how he plays without the puck: how he gets in passing lanes, how he backchecks, how he kills penalties. Those are the skills youth coaches talk about all the time, and they are easy to miss on TV. Practices at City National Arena in Summerlin are another way to get close to the team.

And if you are thinking about a move within the valley, or to Las Vegas from somewhere else, think about game nights as part of your daily life. How far is the drive to the Strip? How close is the nearest rink? Those small details can shape how much you enjoy where you live.
