How Corsi and Fenwick Are Changing Hockey Analytics

28 July 2026

If you're anything like me, you probably grew up watching hockey with one question in mind: “Why the heck doesn’t my favorite team shoot more?” Or maybe, “We had more puck possession, but we still lost—what gives?”

Welcome to the world of advanced hockey stats.

For years, we judged players mostly by goals, assists, and maybe plus-minus (which, let's be honest, doesn’t actually say much). But now, thanks to metrics like Corsi and Fenwick, we’re getting a whole new lens on how teams and players actually perform on the ice. These aren’t just nerdy numbers—they’re revolutionizing how coaches, analysts, and even fans like us understand the game.

So, what exactly are these stats? And why are they making such a big splash in hockey circles? Grab your favorite jersey and let’s dive in.

What Are Corsi and Fenwick?

Corsi and Fenwick sound like they could be the name of a law firm or maybe a couple of 90s NHL enforcers. But nope—they’re actually two of the most important analytics in modern hockey. Here's the simple breakdown.

Corsi: The Total Shot Attempt Tracker

Corsi measures all shot attempts—that means shots on goal, missed shots, and even blocked shots. It’s a way to gauge puck possession by counting how often a team or player is pushing play toward the opponent’s net.

> More shot attempts = more time in the offensive zone = more chances to score. Makes sense, right?

The basic idea? If your team is generating more shot attempts than the opponent while you're on the ice, chances are you're dictating the play. That’s exactly what coaches want to see.

Fenwick: Corsi’s More Refined Cousin

Fenwick is a lot like Corsi but with one key difference—it excludes blocked shots. That’s it.

Why? Because blocked shots might reflect good defensive positioning rather than poor offense. By removing them, Fenwick gives a slightly purer look at who’s actually getting scoring chances that had a shot at reaching the net.

Why Do Corsi and Fenwick Matter?

So now we know what they are, but the big question is—why should you care?

Well, let’s put it this way. Tracking goals and assists is like measuring a player only by the final score on a scoreboard. It shows what happened, but not how it happened. Corsi and Fenwick dive deeper. They’re like the behind-the-scenes footage of a Netflix docuseries—a closer look at the action you might have missed.

These stats are game-changers for evaluating underlying performance. Let me explain.

Predicting Future Success

You know how in poker, the best players don’t just look at their cards—they look at the odds? It’s the same thing in hockey.

Teams with strong Corsi and Fenwick numbers often eventually see better results, even if they’re on a losing streak. Why? Because they’re consistently controlling the play.

This kind of data helps front offices avoid panic moves when the puck isn’t going in. It also helps them spot breakout players ready to explode (think about those guys who “look” good but don’t have the goals to show for it—yet).

Player Evaluation Beyond Points

Corsi and Fenwick also let us see who’s really driving play. Think about players who don’t score often but seem to be on the ice for every good shift. Analytics now prove their worth.

For example, maybe a third-liner doesn't rack up points, but when he's on the ice, his team generates tons of offensive pressure. That’s valuable—like the hockey version of a bassist in a rock band. You don’t hear them all the time, but without them, everything sounds off.

How Are Teams Using These Stats?

Analytics departments are popping up all over the NHL. In fact, some teams have entire staffers dedicated to breaking down Corsi and Fenwick shifts in-game. It’s no longer just about what your eyes see—it’s about what the data confirms.

Coaching Decisions

Want to optimize line matchups? Throw in some Corsi metrics.

Want to know which defensive pairings actually shut down opponents instead of just “looking solid”? Fenwick's got your back.

More and more, coaches are adjusting systems and ice time based on these numbers. It’s not just about “who’s hot” anymore—it’s about who's consistently pushing play and tilting the ice in your favor.

Scouting and Trades

Let’s be real—trades are tough. You’re trying to predict what a player will do in your system, not just what they did somewhere else.

Here’s where Corsi and Fenwick come in handy. A guy with mediocre traditional stats but strong possession numbers? He might just need better linemates or more ice time. Smart GMs are watching these metrics like hawks.

Are There Any Flaws?

Of course! There’s no such thing as the perfect stat. That’s why you never rely on just one number.

Context Matters

A player’s Corsi might be sky-high—but if they're always starting shifts in the offensive zone, that helps. It’s kind of like judging someone’s driving skills based only on how often they hit the gas, not whether they’re in traffic or on the open road.

Same with Fenwick. It doesn’t factor in shot quality. A hundred slapshots from the blue line might not be as dangerous as five high-danger shots from the slot. That’s why analytics folks look at contextual stats too.

Not the Be-All-End-All

The eye test still matters. Corsi and Fenwick should inform your opinion, not replace it. Think of them as part of a bigger toolkit—like combining GPS with your instincts when you're driving somewhere new.

Beyond the NHL: The Impact on Junior and College Hockey

It’s not just the big leagues leaning into advanced stats. Junior programs, minor leagues, and even college teams are getting on board with Corsi and Fenwick.

Why? Because development isn’t just about goals anymore. Coaches want to see who’s contributing to consistent pressure, who moves the puck forward, and who’s affecting play even when they’re not scoring.

Helping Young Players Improve

Imagine being able to tell a 19-year-old, “Hey, you’re not scoring a lot, but you’re dominating puck possession, and that’s huge.” That’s inspiring and useful.

These metrics offer feedback that's less about flashy stats and more about sustainable improvement, which is gold in player development.

How Fans Are Getting Smarter

Let’s talk about us—the fans.

Gone are the days when we just argued about who had the most goals. Thanks to websites, Twitter threads, podcasts, and YouTube explainers, fans are digging into analytics like never before. Corsi and Fenwick are leading that charge.

Wanna impress your buddies during the next watch party? Drop something like: “Yeah, he’s got a low shooting percentage right now, but his Fenwick’s been trending upward. He’s due.” Boom—instant street cred.

Fantasy Hockey Implications

And hey, if you’re into fantasy leagues, these stats are gold. Analytics can help you sniff out value before others see it. They let you find those diamonds in the rough—and we all want bragging rights at season’s end.

The Future of Hockey Analytics

Corsi and Fenwick were just the beginning. The analytics world is evolving fast, and more complex models are being built every day—from expected goals (xG) to zone entries and microstats.

But even in this ever-expanding universe, Corsi and Fenwick remain foundational. Think of them as the basic chords every great musician learns before diving into solos and symphonies.

AI and Real-Time Stats

We’re already seeing companies use AI and camera tracking to analyze every second of ice time. Eventually, we'll have real-time Corsi updates streamed in broadcasts. Imagine watching the game and instantly knowing which team is winning the possession battle.

It’s not just cool—it’s coming.

Final Thoughts: The Numbers Don’t Lie

At its heart, hockey is still about hustle, grit, and great plays. That’s not going anywhere. But if we can add a layer of understanding with data—why wouldn’t we?

Corsi and Fenwick are showing us what our eyes sometimes miss. They're painting a fuller, richer picture of the beautiful chaos we call hockey.

So next time someone says a player’s struggling just because he’s not racking up points, ask them—“What’s his Corsi look like?”

You might just sound like the smartest fan in the room.
