Are Overs Becoming the Sharper NHL Play?

How Totals Are Formed (And Why That Matters)

To answer that, you have to understand how totals are formed. Books price expected goals using team offensive and defensive efficiency proxies, goalie strength, special teams, rest and travel, and then they shade based on anticipated action.

If a specific bettor segment consistently prefers unders, the book can shade downward, making overs more attractive at the margin.

But you need evidence that (a) under preference exists strongly enough and (b) books haven't already priced it. That's where the research tension matters.

How totals get priced:

• Expected goals models (offensive and defensive efficiency)
• Goalie strength (starter vs backup)
• Special teams rates (power play and penalty kill)
• Rest and travel (fatigue factors)
• Shaded based on anticipated public action

If the public hammers unders, books shade totals down. That makes overs better value at the margin.

The Academic Research Tension

On one hand, the 2010-ish academic work that asked "is there an under bias?" found inefficiencies and even identified "simple wagering strategies" with profitable returns in its sample, including the example where betting UNDER 5.5 showed a 54.20% win rate in their dataset slice.

If that under edge was real for that period, and if it was widely adopted, you'd expect the market to respond by tightening or even shading totals lower. In that world, overs could become the better price later.

On the other hand, a more expansive later study (the dissertation on NHL totals market efficiency and heuristic behaviors) concluded the NHL totals market was "largely efficient," with only a marginal above-average return for one tested strategy.

If that conclusion matches today's market, "overs are sharp" is too broad. You'd need a more specific thesis (certain teams, certain total bands, certain schedule spots, or live-betting situations).

The research tension:

• 2010 study found under edge (54.20% win rate at 5.5)
• Later study found market "largely efficient"
• If under edge was widely adopted, books adjusted
• Overs could become better value after market adjusted

If books shaded totals down to capture under money, overs are now the contrarian side.

Five Ways Overs Become Sharper in Practice

So how do overs become "sharper" in practice, without relying on vibes?

1. When the total is depressed by narrative, not mechanics: Some games get pre-labeled as "under games" regardless of the actual shot and chance environment, especially when two teams have reputations for defensive structure. If both teams have quietly increased pace, are generating more slot shots, or are taking more penalties (more PP time), the true expected goals may rise while the narrative remains under-leaning. That's where over value can live.

2. When goalie perception lags reality: Goalie "form" is one of the most mis-modeled public variables. People overweight last start, last highlight, or "he's a big-game guy." But goalie performance is noisy, and even the concept of "hot hand" in goalie performance has been challenged. A 2025 multilevel logistic analysis on NHL goalies found no evidence for the hot-hand theory and even some evidence that good recent save performance negatively impacted next-shot save probability. If the public (or media) treats a goalie as "locked in" and that depresses the total, the over can become a value bet, especially if the teams' chance generation is strong.

3. When backups start and the market overreacts or underreacts: Backup goalies are a double-edged sword for totals. Sometimes the market reflexively bumps the total up, but not every backup is bad, and not every starter is elite. What matters is the gap between the specific starter and specific backup, not the label. A betting strategy piece noted that in recent seasons about 12 to 15 goalies per year start roughly 70%+ of their team's games, leaving 20% to 30% to backups, meaning backups are not rare edge cases. They're structurally part of the schedule. If you treat every backup start as an automatic over, you're just buying a narrative.

4. When "under culture" pushes totals below key numbers: This is the most actionable version of "overs are sharp." If you see totals that used to be 6.0 now routinely priced at 5.5 in similar matchups despite evidence of higher scoring environments league-wide, overs can be the value side at 5.5 because of the way hockey totals distribute around 5 and 6. A half-goal is not a "small" move in hockey. It's often the entire bet.

5. Live overs when game state breaks the pregame model: Pregame totals assume a certain penalty rate, a certain pace, and a certain degree of finishing. Live betting lets you see whether the assumptions are wrong. If both teams are generating sustained pressure, taking penalties, and creating rebound chaos, you can find live overs at numbers that are still anchored to the pregame reputation of the teams.

The Goalie Hot Hand Myth

Goalie "form" is one of the most mis-modeled public variables. The public overweights last start, last highlight, or "he's a big-game guy."

But goalie performance is noisy. A 2025 multilevel logistic analysis on NHL goalies found no evidence for the hot-hand theory. In fact, there was some evidence that good recent save performance negatively impacted next-shot save probability.

If the public treats a goalie as "locked in" and that depresses the total, the over can become a value bet.

Why the goalie hot hand is a myth:

• Goalie performance is noisy (small samples don't predict future)
• No evidence for hot-hand theory (2025 study)
• Good recent performance might negatively impact next performance
• Public overweights last start when pricing totals

If the public thinks a goalie is "locked in" and the total drops to 5.5, the over is often value. The goalie hot hand is a myth that creates betting opportunities.

The "Under Culture" Key Number Trap

This is the most actionable version of "overs are sharp." If you see totals that used to be 6.0 now routinely priced at 5.5 in similar matchups despite evidence of higher scoring environments league-wide, overs can be the value side at 5.5.

A half-goal is not a "small" move in hockey. It's often the entire bet.

The under culture key number trap:

• Totals that used to be 6.0 now priced at 5.5
• Market adjusted for under preference
• Higher scoring environments league-wide
• Overs at 5.5 are value because of distribution around 5 and 6

If the public has pushed totals from 6.0 to 5.5 because of under culture, overs at 5.5 are the sharp play.

The Bottom Line on NHL Overs

Are overs becoming the sharper NHL play? Sometimes, specifically when unders have become a social identity and totals have been shaded down accordingly, or when goalie narratives depress prices incorrectly.

The academic research supports this. If the under edge from 2010 was widely adopted, books adjusted by shading totals down. That makes overs better value now.

Five ways overs become sharper: when the total is depressed by narrative not mechanics, when goalie perception lags reality, when backups start and market overreacts or underreacts, when "under culture" pushes totals below key numbers, live overs when game state breaks pregame model.

The goalie hot hand is a myth. No evidence for hot-hand theory. Public overweights last start. If the public thinks goalie is "locked in" and total drops, the over is value.

The "under culture" key number trap is the most actionable edge. If totals that used to be 6.0 are now 5.5, overs at 5.5 are sharp.

The sharp approach isn't to become an over bettor. It's to become a price-first bettor who is willing to take overs when the market is underpricing offensive volatility.
