Shot-attempt differentials make more sense when you picture the shift every defenseman dreads: burning legs and a puck that keeps coming back. A forward pins it against the end boards. His teammate arrives for support, nudges it loose, and sends it toward the blue line.
The defenseman drops into the shooting lane. Rubber smacks his shin pad. For a second, he sees a chance to escape.
Then the wrong jersey reaches the rebound.
Imagine that sequence repeating before the defending team can change. Nobody has scored, and the goalie might not have made a save. Still, the attackers have forced another turn, another board battle, another decision under pressure.
That work matters. Counting attempts captures some of it, including shots that miss the net or hit a defender.
But the exhausted defenseman leaves us with a harder question. Did his opponents spend the shift creating dangerous chances, or did they keep shooting because he denied them anything better?
To judge five-on-five dominance, we need to follow the puck through both stories.
Start with the attempts then check the score
The basic calculation takes seconds. Shot-attempt differentials subtract the opposition’s attempts from your team’s attempts. Understanding what that margin reveals takes a little more care.
Separate the margin from the share
Take a hypothetical game in which one team generates 60 attempts and allows 40 at five-on-five. That produces a plus-20 differential and a 60 percent attempt share.
Plus-20 describes the numerical advantage; 60 percent describes how the teams divided the attempts. Neither figure means the stronger team possessed the puck for 60 percent of the playing time. The percentage measures shooting activity, including attempts that never reach the goalie.
For a clean comparison, isolate five-on-five minutes with both goalies in net. A power play creates different passing lanes, while pulling the goalie changes the defensive risk entirely. Even-strength totals can also include four-on-four and three-on-three play, so check the filter before comparing teams.
Similar numbers can describe different hockey
Now imagine two clubs over an equal stretch of five-on-five ice time. One generates 70 attempts and allows 50 per 60 minutes. Another produces 50 and allows 30.
Both sit at plus-20 per 60, but the first owns roughly 58.3 percent of attempts; the second owns 62.5 percent.
Watch their games and the difference could feel enormous. The first matchup might send both goalies sliding across their creases. In the second, an opposing forward might spend entire shifts searching for an open shooting lane.
Per-60 rates put teams on an equal time basis, using the calculation Evolving-Hockey outlines in its statistical glossary. Read the attempts for and against separately, rather than letting one differential hide how a team reached it.
A coach looking at those hypothetical clubs would have different questions. Does the first need fewer risky pinches? Could the second afford to push another attacker toward the net?
Protecting a lead can muddy the picture
With four minutes left and a two-goal cushion, a winger reaches the puck along the boards. He could try a pass through the middle. Instead, he chips it out and heads for the bench.
The decision costs his team a possible attack. It also avoids a turnover between the circles.
When safe plays surrender shooting volume
Repeat enough of those choices and the trailing team can pile up attempts without having controlled the earlier game. Raw shot-attempt differentials record the resulting imbalance, but they cannot explain the decisions behind it.
Leading teams sitting back deserve particular attention here. In his February 2020 study of score effects, HockeyViz analyst Micah Blake McCurdy found that behavior drove shot-rate changes more than trailing teams pressing.
That finding does not excuse every defensive retreat. A team surrendering repeated rebounds beside its crease cannot explain away those chances simply by pointing at its lead.
Check whether the advantage survives adjustment
Compare raw results with score-adjusted numbers and, when enough minutes exist, tied-game play. Evolving-Hockey’s published adjustment weights account for score state and home-away differences. Those weights help address recurring patterns; they do not replay the game under identical circumstances.
If a team keeps its territorial advantage across those views, the argument grows stronger. A sharp drop after adjustment demands a closer look at when the attempts occurred and what the opposition conceded.
The lead explains why a winger chose the safe chip. Film reveals whether his team then protected the middle or spent the remaining minutes scrambling around its crease.
Follow the blocked shot through the film
Freeze a hypothetical sequence just before a defenseman shoots from the right point. A defending winger crouches in the lane, his stick extended. Behind him, the center protects the slot.
The shot strikes the winger and skips toward the wall.
What Corsi counts and Fenwick leaves out
Corsi counts the block alongside goals, saved shots, and misses. Fenwick excludes it, following the distinction in Evolving-Hockey’s glossary. That boundary gives a coach something specific to investigate.
If the defending winger keeps stopping point shots before they reach the slot, the attackers may need a different angle. A pass across the blue line could move him. Working the puck below the goal line might force the center to turn.
But a block does not automatically end an attack. Should the puck land beside an uncovered forward, the defending team faces a far worse problem than the original point shot.
That is why shot-attempt differentials need a chance-quality check. The count remembers each attempt equally, while the goalie experiences very different threats.
Give the shooting lane a value
Expected goals tries to describe that difference. Shot location, shot type, preceding events, and manpower help MoneyPuck’s model estimate the probability of a goal.
Other providers make their own modeling choices. As Evolving-Hockey explains in its methodology, public expected-goals estimates can therefore disagree. Use one provider consistently when comparing performances, then check whether the video supports the pattern its model identifies.
Return to the film. An unscreened wrist shot from near the boards lets the goalie square up and track the release. A rebound near the opposite post might leave him reaching across open ice.
When attempt share favors a team but expected-goals share does not, look closer. Search for point shots hitting set defenders, empty space around the crease, or counterattacks following failed pinches. Those details show where a territorial advantage might be leaking away.
Carolina puts a forecheck behind the percentage
Carolina led the league with 58.4 percent of five-on-five attempts in 2024–25, NHL writer Troy Perlowitz reported in his August 2025 review. That number gains meaning when you consider how Rod Brind’Amour’s teams pursue the puck.
Win the retrieval and begin again
Hard forechecking, patience, and capitalizing on chances formed the approach Brind’Amour described to NHL reporter Dan Rosen during the 2025 Eastern Conference Final. Rosen’s reporting placed that aggressive pressure at the center of Carolina’s identity.
Picture how the approach can sustain an attack. The first forechecker forces a hurried pass along the wall. Support arrives before the defending winger can turn up ice. A defenseman holds the blue line, and the puck goes back behind the net.
The attacking team has earned another possession inside the same shift. Its opponent has lost another chance to change.
That pressure disrupted Washington in the 2025 second-round opener, as NHL reporter Tom Gulitti documented in his game coverage. Seen through that lens, shot-attempt differentials help describe the repeated work behind Carolina’s volume. Recoveries keep attacks alive; failed exits make defenders begin again.
Pressure still needs a finish
The system still needs someone to beat the goalie. Florida eliminated Carolina in five games later that spring, with Rosen’s series analysis detailing how the Panthers handled the pressure game themselves.
Carolina’s territorial identity gave the Hurricanes a way to compete. It could not guarantee they would solve every opponent. The distinction matters when assessing a team whose pressure looks convincing long before the puck crosses the goal line.
Find the player who made the exit possible
Below the faceoff dots, a center curls toward his defenseman and offers a short pass. One touch moves the puck away from the forechecker. Another teammate carries it through the neutral zone.
By the time the line shoots, the center might never appear in a conventional scoring summary.
Follow the contribution beyond the shooter
Player-level shot-attempt differentials can help flag shifts worth examining. They also credit or charge everyone sharing the ice, including players who contributed little to that particular sequence.
Comparing a player with his teammates adds another useful angle. Evolving-Hockey’s relative-to-teammate measures do that through weighted on-ice rates, although the comparison cannot settle individual responsibility alone.
Watch who supplied the outlet, who held the puck under pressure, and who covered the advancing defenseman. Those actions explain more than a flattering percentage beside one name.
Imagine Colorado trying to replace Cale Makar for a stretch. The useful question would reach beyond replacing his shots. Which defenseman now escapes the first forechecker and delivers the pass that starts the attack?
What holds up when the puck comes back
The next test arrives with another dump-in. A defenseman checks over his shoulder, judges the forechecker’s speed, and decides whether to reverse the puck.
That small decision helps determine where the next attempt happens.
Over a growing sample, shot-attempt differentials can reveal which team repeatedly wins that exchange. Still, the sample needs attention. A new pairing, a changed assignment, or an unusually long stretch of protecting leads can alter the numbers.
Start with attempt share and the separate rates for and against. Check score effects before declaring that one team dictated the game. Then examine chance quality and return to the shifts that produced it.
The strongest case for five-on-five dominance comes when those observations agree. A team retrieves pucks, exits cleanly, sustains attacks, and reaches dangerous ice while denying opponents the same access.
Finishing and goaltending can still decide the night. One shooter can miss an open corner; another can score through a screen on his first chance.
Those outcomes matter, but they answer a different question from whether the underlying play deserves confidence.
A coach reviewing tomorrow’s opponent needs both answers. He must know who keeps the puck coming back and who turns that pressure into a threat.
Back at the bench, the exhausted defenseman finally catches his breath. When he watches the shift again, will he see shooting lanes he protected or chances he barely survived?

FAQs
Q1. What are shot-attempt differentials in hockey?
A. Shot-attempt differentials subtract attempts against from attempts for. They include goals, saved shots, misses, and blocked shots.
Q2. What is the difference between Corsi and Fenwick?
A. Corsi counts all shot attempts, including blocks. Fenwick excludes blocked shots but still counts goals, saved shots, and misses.
A. No. It means a team took 60 percent of the combined attempts. It does not measure how long that team held the puck.
Q4. Why does protecting a lead affect shot-attempt numbers?
A. Teams protecting leads may choose safe clears over attacks. Their opponents can then accumulate attempts, which changes the raw differential.
Q5. Can a team win the shot-attempt battle and still lose?
A. Yes. Attempt totals do not capture every difference in chance quality, finishing, or goaltending. A team can generate more attempts and still lose.
