Who Benefits When an NHL Top-Liner Gets Hurt? Measuring the Real Bump

The short answer: who benefits from a top-line injury?

The forward who gets the spot, and the lower his usual scoring, the bigger the jump. Here is the typical change in even-strength points per game for a forward moved onto a line with one of his team’s top two scorers.

Use the live numbers on our Who Benefits pages. Every forward listed as a likely beneficiary of a top-six injury now shows his own expected change, labelled “if he takes the spot.”

How we measured it

We took every regular-season game from 2017-18 to 2025-26 where one of a team’s top two scorers played without one of his two usual linemates. NHL shift data told us exactly who took the empty spot. That gave 6,054 games across 730 stretches.

For each fill-in we used only what was known before the game: his even-strength points over his previous 82 games. Then we compared what he scored on the line with that rate.

The bounce-back problem

Here is the trap in most pickup advice. A forward stuck at 0.15 points a game over his last stretch is partly unlucky. He would likely score more next week anyway. So we measured how much forwards at each scoring level beat their recent rate in games where they were not promoted, and divided that out.

For depth forwards the bounce-back alone is worth 12%. That is why the raw 1.68× becomes a 1.50× bump. Over a 20-game window the bounce-back is bigger still, and the honest bump shrinks to 1.33×. Short hot and cold streaks mislead in both directions.

The fill-in is not the player he replaced

• Promoted forwards produced about 82% of the missing regular’s even-strength scoring (90% range 79%–86%).
• On the power play the gap is wider: fill-ins kept 65% of the regular’s power-play points.
• The star loses something too: his own even-strength scoring dips about 9% without his usual linemate.

In fantasy terms: the add is real, but do not expect the injured player’s numbers. Expect the fill-in’s own rate, raised by his tier’s bump.

Forwards with no power-play role do pick up some power-play points when they join a top line, about 0.08 a game instead of 0.04, likely from spot duty. Forwards who already had a power-play role gain nothing there.

Is there such a thing as a “promotion guy”?

Fans often say a certain winger “always produces with the stars.” We tested it. For 44 forwards with at least 8 promoted games in both odd and even seasons, we compared how much each beat his expected bump in one set of seasons with the other.

There is no sign of it. Who benefits depends on how much a player usually scores, not on a special knack. A depth winger with a reputation for “clicking” with the stars should get the depth-forward bump, no more.

Does it predict better than the obvious guesses?

We fit the model on 2017–2020 and scored it on 2021–2026, which it never saw. Knowing a forward was promoted improved the forecast of his even-strength points in those games: error fell from 1.023 to 1.004 (Poisson deviance, 3,072 promoted games).

One warning from the same test. Projecting a fill-in from his last 20 games, raw, did worse than simply assuming the league-average fill-in (1.100 vs 1.013). Short windows are too noisy. Use a season’s worth of games, then apply the bump.

And the bump only applies if he actually gets the spot. Coaches change their minds, and many projected roles revert within a few games. That is why our projections do not add the bump automatically: it is shown as “if he takes the spot,” for you to weigh against tonight’s line combinations.

Has the bump changed over time?

Barely. Using scoring summaries back to 1959-60, the promotion bump has stayed between 4% and 13% for an average fill-in in every era (1,945 line vacancies, 1959–2026). What changed is the gap below the top line: the next forward up used to score about 82% of the regular’s rate, and since the early 1990s it has been 75–77%. The full history is in our GOAT series piece on linemates.

Do betting markets price the promotion?

Not proven either way yet. We checked the first 10 days of 2026-27 player props we logged (October 6–15), comparing players who were promoted onto a top scorer’s line that night with the market’s no-vig price.

Every market leaned the same way, and the market priced promoted players about the same as everyone else. But none of the gaps is statistically meaningful, the four markets are the same 65 players, and with a looser definition of “promoted” the lean disappears (−1.7 points across 106 player-games). We also tagged promotions after the fact, which a bettor cannot do.

• Props: over on a depth or middle-six forward projected into an injured regular’s top-six spot. Bets: At the props lock (~75 min before puck drop), when a same-team regular is out and Ascension projects the player into his L1/L2 spot, and the player’s usual EV rate is under 0.45 points a game: points and shots over, 1 unit flat at the best US price. Our model edge is ignored (it does not know about promotions). Live since October 16, 2026: 23–23–0 (W–L–P), +3.63u, ROI +7.9%. Sample: 46 of 300 graded bets; pre-registered read: one read at 300 graded bets: profit above zero, a 95% lower bound above −5%, and still positive without DraftKings prices. Staking: 1 unit risked per bet at the best US price at the lock, about 75 minutes before puck drop. Status: Watch list, unproven: 46 of the 300 graded bets needed for its read.

What a unit means. A unit (u) is the flat stake on every bet: we risk 1 unit at the price we logged, so a win at +150 earns +1.50u and a loss costs −1u (to risk, not to win). ROI is units won divided by graded bets. Pushes and voids return the stake and are not counted as bets. Record as of October 21, 2026; results are graded several times a day once games are final. Every bet, losses included, is on the betting test, and every test is on the live tests scoreboard.

Until then, treat this as fantasy research, not a betting edge. Books see the same line combinations you do, and a 50% bump on a 0.20-a-game forward still leaves him a long shot to score in any one game.

How to use it

1. When a top-six forward is ruled out, check who is projected into his spot on Who Benefits and tonight’s lines.
2. Prefer the depth forward who gets the job: his bump is the biggest, about +50% at even strength.
3. Expect about 80% of the injured player’s even-strength scoring at best, and less on the power play.
4. Ignore “he always produces with the stars” stories. They do not repeat.
5. Drop him when the regular returns: the bump goes with the spot.
