John Chayka has already put his stamp on the Maple Leafs this offseason. Toronto landed the No. 1 pick in Gavin McKenna, added size and depth up front, and reworked the blue line. Even after that, though, there are still a few obvious places where the roster can be strengthened, and three teams stand out as realistic trade partners once the season gets closer.
That doesn’t mean a deal is around the corner. It just means Chayka looks prepared to strike if the right name surfaces.
One of the clearest fits is in Calgary, where center Morgan Frost keeps popping up in trade chatter. The Flames are deep into a rebuild, and Frost is in the final year of a manageable contract after a career season that produced 22 goals and 43 points. Calgary GM Craig Conroy has made it clear he’s open to moving players who don’t fit the long-term picture, which puts Frost squarely in the conversation.
Daniel Austin of the Calgary Sun wrote:
“Given the opportunity that lies ahead of him, Frost will surely want to put up big numbers this year and earn a bigger deal. It may be worth it for the Flames to give him that opportunity. Their salary cap isn’t an issue going forward, so if he has a great year they’ll be able to reward him.”

If Frost blows up this season and starts looking like a player who wants to test the market, Calgary could be better off moving him while his value is high. For Toronto, he would fit a major need. The Maple Leafs are still looking for center depth behind Auston Matthews and John Tavares, and Frost checks a lot of boxes.
Pittsburgh is another situation worth watching. The Penguins have Bryan Rust and Rickard Rakell out there in trade talk already, though the market hasn’t met the price Dubas wanted. Then there’s Erik Karlsson, who is in the final year of his contract and could become a real decision point if Pittsburgh slides out of the playoff picture.
If the Penguins aren’t in position to contend, dealing one of those veterans before they can leave for nothing would make sense. For Toronto, Karlsson is the most intriguing of the bunch, especially after the Leafs were in on Zach Werenski if he didn’t stay in Columbus. Karlsson could become a fallback option.
There are obvious hurdles. His willingness to move matters.
So does the cap. So does the price.
He’s 36, but he still brings real value as a puck-moving defenseman on the right side. He likely wouldn’t replace Darren Raddysh on the power play, which limits some of what he can do, but a pairing with Morgan Rielly would be interesting.
It’s not the kind of name most Leafs fans would automatically circle, and there are reasons to be cautious. Even so, Chayka could test the waters with a lowball offer that includes salary going back, just to see whether Pittsburgh or Karlsson would take it. Rust and Rakell, meanwhile, are already known quantities in terms of what it would take to pry them loose.
Then there’s Werenski, the player Toronto was clearly prepared to pursue. That possibility disappeared when he pivoted back and did a 180 on his decision to leave the Columbus Blue Jackets. For now, the trade that might have been is off the board.
But not necessarily forever. If Columbus struggles and Werenski decides he’s not ready to commit to a franchise that can’t seem to get its ducks in a row, Toronto would be ready to jump back in. He’s the reigning Norris Trophy winner, and only a few defensemen offer that kind of impact.
The Leafs would be willing to pay a steep price if Werenski came available and was open to signing an extension. Matthew Knies would likely be part of the conversation, along with other players the team would normally treat as untouchable. Chayka, it seems, already had an offer in mind before Werenski changed course, and there’s no reason to think that basic framework would change much if the door opens again.

Flames Face One Tough Blue Line Decision Before Camp
The Calgary Flames are entering camp with an unusual kind of problem on the blue line: too many defensemen and not enough regular-season jobs to go around. A group that looked sturdy on paper now has to be sorted out before the schedule begins, and that kind of surplus usually forces a front office to make some uncomfortable calls while there is still time to act.
For the Flames, the issue is less about finding depth than deciding which pieces fit into the long view. A logjam on defense can create value in the trade market, and it can also leave players wondering where they stand once camp opens. However it shakes out, this is one of those preseason questions that can shape the roster well beyond opening night. [Read more 🡒]
Dustin Wolf Is About To Learn How Much Respect Hes Earned
Dustin Wolf has spent the better part of his first stretch in Calgary giving Flames fans a reason to believe in the crease even as the team has gone through its share of struggles. The young goaltender has been steady enough that plenty around the organization already view him as a top-tier NHL netminder, and that kind of respect tends to show up in conversations like the one NHL Network is preparing to have ahead of the 2026-27 season.
NHL Network is set to unveil its top 20 goaltenders ranking on Sunday night, and Wolf looks like a strong candidate to be included among the leagues better starters. For Calgary, the interest goes beyond the number next to his name, because it is one more measuring stick for how the rest of the hockey world sees a goalie who has already earned plenty of trust inside the fan base.
