Quick answer: Plus-minus is a hockey statistic that tracks the goal differential while a specific player is on the ice. A player gets +1 every time their team scores at even strength while they’re on the ice, and -1 every time the opponent scores at even strength while they’re on the ice. Power-play and shorthanded goals generally don’t count toward plus-minus, with shorthanded goals being a notable exception in some cases.
What the Stat Actually Captures
Plus-minus aggregates context-blind goal differential. A player on a great team will accumulate a high plus-minus partly because they happen to be on the ice when their team scores, regardless of whether they directly contributed. A player on a bad team will rack up minuses for the same reason in reverse. Connor McDavid posted a +28 in 2022-23 because the Oilers outscored opponents by a lot at 5-on-5. That doesn’t mean McDavid was 28 goals’ worth of better than league average, just that his team was good.
Why Sharp Bettors Treat It as Suspect
Plus-minus has well-known limitations as a player evaluation tool. It doesn’t account for the quality of teammates or opponents. It treats a defenseman who plays 25 tough minutes per game the same as a 4th-line winger who plays 9 sheltered minutes. Modern hockey analytics use Corsi, Fenwick, expected goals, and Wins Above Replacement to do what plus-minus tries to do, but better. For betting purposes, plus-minus is mostly noise.
The Limited Prop Application
Plus-minus props exist but are rare. Most books offer plus-minus over/under for a single game (over +0.5 means the player’s team must outscore opponents while they’re on the ice). The market is thin and the lines are often wide because books can’t model it precisely. Sharp bettors usually pass on plus-minus props in favor of higher-volume markets like SOG and goals. PropsBot’s NHL model graded 29,189 NHL props with 86.5% Win Rate on the High Hit Rate Signal, but plus-minus is not where that edge comes from. We focus on volume markets where the data signal is cleaner.
Records Worth Knowing
Bobby Orr’s +124 in 1970-71 is the all-time single-season record. Boston was so dominant that season that Orr’s number reflects an era as much as a player. Modern era leaders rarely exceed +50 in a season. Single-game records are less interesting because plus-minus per game is bounded by total scoring. The career leader is Larry Robinson at +722, accumulated across his Montreal years.
Frequently Asked Questions
How is plus-minus calculated?
+1 for each even-strength goal scored by your team while you’re on the ice. -1 for each even-strength goal scored by the opponent while you’re on the ice. Power-play goals usually don’t count (shorthanded goals scored against you do).
Why is plus-minus considered a bad metric?
It doesn’t account for teammate or opponent quality, ice time, or competition difficulty. Modern analytics like expected goals and WAR replace it for serious player evaluation.
Can a goalie have a plus-minus?
No. Plus-minus is a skater stat. Goaltenders are evaluated by save percentage, goals against average, and modern stats like Goals Saved Above Expected.
Are plus-minus props worth betting?
Generally no. The market is thin, the variance is high, and the underlying stat is too noisy to model accurately. Sharp bettors usually skip these in favor of volume props like SOG and saves.
What counts as ‘on the ice’ for plus-minus?
The skater must be physically on the ice when the goal is scored, including any moment from the puck drop to the goal. Bench-warming time doesn’t count even if your line just came off.
