THE COST OF GETTING IT WRONG.

Brad Treliving needed a win. Toronto was sitting outside of a playoff spot. Ownership wanted a move. Carlo was available and Boston was willing to deal — for a price.

The fair price was a first round pick. That was the market rate for a veteran shutdown defenceman with two years left on his deal. Toronto should have paid it and moved on.

Boston also asked for Fraser Minten. That was a low-risk ask on their part — the worst Toronto could say was no. In 15 games before the trade, Minten had scored 3 goals. At 22 years old on an $816K ELC, projecting to 16 goals over a full season, every team in the league knew what that combination meant. Boston knew exactly what they were asking for.

A GM thinking about his team says no to Minten and pays the pick. A GM fighting for his job says yes to everything.

Carlo played 55 games. Toronto finished where they would have finished without him. The pick was saved by a lottery draw at 8.5% odds. Minten scored 17 goals in Boston.

The 1st round pick cost nothing in the end. Minten cost everything.

Slashing does not prevent desperation. But it removes the excuse that the data wasn't there. Every other tool is a rearview mirror. Slashing is the windshield.

Every summer a contender signs a 40-something veteran for the room, the experience, the playoff scar tissue. The market prices it as a courtesy. Los Angeles signed Corey Perry to one of those deals — $2 million, one year, fourth-line minutes — then traded him to Tampa Bay at the deadline.

By the time the season ended, he had produced $1.9 million more in net impact than his cap hit cost. Not top-ten. Not a headline. Just a player who did exactly what he was asked, from the places it counts, at a price two teams were happy to pay.

This is not a finishing mirage. Thirteen of his seventeen goals came from the high-danger area, and eleven of them either gave the team the lead or tied the game. One empty-netter all year. He scores the goals that decide games, from the places goals are supposed to come from.

Two honest qualifiers, because Slashing does not sell fairy tales. This is a per-60 story, not a volume one — 17 goals across 72 games is depth output, and his value lives in the minutes he plays, not their number. And he is deployed correctly — the right situations, the right spots. That is not a knock. It is the point: the role fit the player, and the player delivered a surplus. That is the whole game.

Most teams overpay for the name on the back. Both teams that carried Perry this season underpaid for the impact.

A 32-goal season looks ordinary on the boxscore. Good year, mid-tier winger, move on. Slashing's expected goals model tells a completely different story.

Mantha took the shots of an 18-goal scorer and finished like a 32-goal scorer. His Goals Above Average — actual goals minus what his shot locations predicted — is +13.83, the highest in the entire league. Not Caufield. Not Kucherov. Mantha. His finishing rate is 1.76× expected. That is not a hot month. It is 81 games of burying chances that an average shooter leaves on the ice.

And the chances were not cheap looks: 81.2% of his goals came from the high-danger area, more than double the league rate. He gets to the hard ice and then he beats the goaltender from there. That combination — volume of dangerous chances plus elite conversion — is the most expensive skill in hockey, and Pittsburgh is renting it for $2.5M.

We will be honest where other tools are silent: Mantha is a one-way player. His Net Impact Score, which charges him for goals against while he is on the ice, lands at 0.680 per 60 — a two-way value about $600K short of his cap hit. That is the whole trade, stated plainly: the defense costs you six hundred thousand, and the finishing — the best in the league — is what you get for it. No one sells this skill cheaper.

He is a pending unrestricted free agent. Every team that needs goals is about to ask what he is worth. Slashing has the answer before the bidding starts.

Dylan Holloway was an Edmonton Oiler — a young, ascending forward in a system built around two of the best players alive. He should have been exactly the kind of cheap, vibrant, term-controlled asset a contender builds its depth on. On August 20, 2024, St. Louis signed him to an offer sheet. Edmonton chose not to match.

The number St. Louis committed was $2,290,457 a season. On that contract, in 2025-26, Holloway posted a 2.264 NET/60 — #16 in the NHL, ahead of names making four and five times his salary. He scored 20 adjusted goals on 17.4 expected, finishing above his chances. His cost per adjusted goal was $114,523 against a $200,000 market. Every one of those numbers was available to Edmonton before they let him walk for a second-round pick.

Then St. Louis signed him to a five-year extension at $7.75M, covering his age-25 through age-29 seasons — his prime. Is $7.75M above his current value? Yes — by our number he is a $6.23M player today. But that is the price of locking up a 24-year-old who already produces like a top-line forward and is still getting better. St. Louis is not paying the upside tax. They already collected the surplus, and now they own the prime.

The mistake was never St. Louis's bet. It was Edmonton's exit.

During the 2026 Draft, Dallas reportedly offered Robertson to Seattle. Seattle came back with $15 million per year over eight years — $120 million guaranteed. Robertson turned it down. He is an RFA — Dallas holds his rights. What the rejection confirms is that the open market values him well above the club's reported $12 million ceiling.

By Net Impact Score among all forwards with 70 or more games played, Robertson ranked 6th in the NHL this season — ahead of every forward already earning $12 million or more. The data supports a number above the club's ceiling. NIS measures one season on purpose. It prices what he produced this year against what it cost — not what the next eight years will look like.

Dallas can play the season with him unsigned and revisit at the deadline. Robertson can hold his position and wait. The data says what he was worth this season. What either side does with that is the negotiation. Slashing puts the number in the room. The rest is up to the people in it.
