Semyon Der-Arguchintsev Wants Back In With the Maple Leafs. One NHL Rule Is in the Way

Semyon Der-Arguchintsev and the Maple Leafs: the pitch is real

Semyon Der-Arguchintsev wants to play for the Maple Leafs again, and his camp has stopped being subtle about it. The 25-year-old centre had his KHL rights shipped to Admiral Vladivostok this week, and his agent, Shumi Babaev, told Russian outlet RB Sport that his client has no intention of reporting there. The goal, per those reports, is an NHL contract for 2026-27, and the preferred destination is the organization that drafted him.

This is not a new idea. Babaev first floated a Toronto return back when Brad Treliving still ran the hockey department, and the reported message then was that the player wanted back into the Leafs' system. Treliving is gone. John Chayka has been the general manager since May, and by the agent's own telling, the conversation restarted once the new front office was in place. Babaev has since acknowledged a process is underway without offering details.

So the interest is genuine on one side. What makes this more than a nostalgia item is the reason it has not already happened — and it has nothing to do with whether Der-Arguchintsev can play.

The waiver problem is the whole story

Der-Arguchintsev signed his first NHL contract in September 2018 and burned through four professional seasons on it. Waiver exemption in the NHL is a function of age at signing and professional seasons played, and his ran out years ago. That single line of bookkeeping is what turns a low-risk depth signing into a genuine roster decision.

Here is the practical version. If Toronto signs him to a two-way NHL deal and decides in late September that he is the 14th-best forward in camp, the Leafs cannot simply send him to the Marlies the way they would a 22-year-old prospect. He would have to clear waivers first, in front of all 31 other clubs. A 25-year-old centre coming off 37 points in 57 KHL games is exactly the profile a rebuilding team claims for free, and Toronto would lose him for nothing after doing the work of recruiting him.

That is why an organization with a full NHL roster and a cap problem does not rush this. It is also why the smart move, if Toronto is serious, is an AHL contract or a training-camp invitation rather than a one-way commitment — an arrangement that lets both sides look at each other without a waiver claim hanging over it.

What he actually did in Russia

Der-Arguchintsev left North America after the 2022-23 season and has spent three years in the KHL with Traktor Chelyabinsk and Dynamo Moscow. Over that stretch he put up 101 points — 36 goals, 65 assists — in 171 regular season games. The most recent campaign was his best distribution year: six goals and 31 assists in 57 games, a rate that reads as a legitimate top-six playmaker in a league that is, on most nights, the second-best in the world.

That is a meaningful improvement on the player Toronto gave up on. The knock on Der-Arguchintsev as a Marlie was always the same: excellent vision, soft hands, and not enough pace or strength to survive when the ice shrank. He was a power-play specialist looking for an NHL body. Three years of KHL minutes do not fix skating, but they do fix confidence, and the volume of assists suggests the playmaking translated up a level.

Where he would fit, and it is not where you think

Toronto's forward group is not short of bodies. Chayka spent July stacking the bottom half of the lineup with Colton Sissons, Teddy Blueger, Brandon Duhaime and Jack Roslovic, and every one of those contracts is guaranteed NHL money. Add Auston Matthews, William Nylander, John Tavares, Matthew Knies, Nick Paul, Dakota Joshua and Steven Lorentz, plus a first-overall pick in Gavin McKenna who is not going to the AHL, and the opening-night 12 is essentially spoken for.

The real fit is insurance. Toronto's 2025-26 season came apart in part because the injury replacements were not NHL players, and the Marlies' centre depth thinned out again this summer. A skilled centre who can run a second power-play unit in the AHL and step in for ten games when someone tweaks a groin has actual value — provided he can be stashed. Which brings the whole thing back to waivers.

The precedent Toronto keeps ignoring

Russian returnees are one of the few genuine market inefficiencies left in a capped league. Teams have repeatedly found useful NHL players in the KHL's 25-to-28 bracket for the price of a two-way deal, because the pool is thin, the scouting is inconsistent, and the visa and transfer friction scares off clubs that would rather sign a known AHL veteran. Toronto has generally not played in that market, preferring to fill its fourth line and its Marlies top six with North American depth on guaranteed money.

Chayka's public reputation is built on exactly this kind of arbitrage — buying production the rest of the league has priced wrong. If that reputation is real, a player who scored at better than a half-point-per-game clip in the KHL and is willing to sit out a season to force his way to one specific city is precisely the file you take seriously, even when the roster math is unfriendly.

Why Chayka might say no anyway

There is a version of this where Toronto passes and no one should be surprised. The Leafs are roughly $2.75 million over the $104-million ceiling before any of this, a situation they will most likely resolve through Max Domi's long-term injured reserve status rather than through generosity. Every additional NHL contract is a complication in a summer that has had enough of them.

There is also the roster-spot argument. The organization has spent two years insisting its young forwards need runway, and the AHL age rules already squeeze how those minutes get distributed. Handing a Marlies top-six job to a 25-year-old returnee is a defensible hockey decision only if you believe he is genuinely better than the prospects behind him. Toronto's development staff would have to make that case internally.

The reasonable outcome

Our read: this ends with a professional tryout or an AHL deal, not an NHL contract. Toronto has no cap room, no open roster spot, and no ability to hide him if it goes badly. A camp invitation costs nothing, gives the coaching staff two weeks of live looks, and preserves the option of a conversion to an NHL deal in November if injuries hit — which is precisely how the Leafs have handled this class of player before.

The alternative is that Der-Arguchintsev, who has already refused to negotiate with Admiral, spends the fall without a contract on either continent while he waits. That is a real risk he is choosing to take, and it is the most convincing evidence available that the interest in Toronto is not posturing. Players with leverage do not sit out. Players who want one specific thing do.

What's next

Nothing about this requires a decision before September. KHL clubs need bodies and Admiral holds his rights there, so a deadline could get manufactured on the Russian side if Vladivostok pushes. On the Toronto side, the sequence is cap compliance first, camp invitations second. Watch the Leafs' PTO list when it surfaces in the week before training camp opens in September — if his name is on it, the reporting was right. If it is not, this was a summer story that never had a mechanism behind it.
