Rookie Watch: Is Matthew Schaefer Already “That Guy” — And Can Ryan Leonard Match His Breakout?

Rookie Watch: Is Matthew Schaefer Already “That Guy” — And Can Ryan Leonard Match His Breakout? Every rookie class arrives with a pre-built marketing plan. This year’s hype cycle has revolved around the usual headliners: Ivan Demidov in Montreal, Macklin Celebrini in San Jose, Leo Carlsson in Anaheim, and so on. But while fans and panel shows argue about which future superstar is “next,” two other names have quietly started to break the NHL in real time — and the numbers are getting hard to ignore.

On Long Island, 18-year-old defenseman Matthew Schaefer is doing video-game things for a rookie blueliner. Through 19 games, the 2025 first-overall pick sits at 7–8–15, leading all NHL rookies in points and all defensemen in goals. ESPN.com+2StatMuse+2 He’s also logging over 22 minutes a night, with the Islanders controlling more than half of the shot attempts and goals at five-on-five when he’s on the ice. NHL+1

Down in Washington, Ryan Leonard is building a very different kind of rookie résumé. He’s “only” at 3–5–8 in 18 games, but he already has 27 hits, a 57 percent goals-for share at five-on-five, and glowing public reviews from coach Spencer Carbery, who has called him one of the rare 20-year-olds he doesn’t need to shelter.

One is a minute-munching, record-chasing defenseman. The other is a hit-machine winger with enough skill to play in the top six. Both look like players who could swing fantasy leagues and reshape their franchises’ timelines.

So the question for both NHL fans and fantasy GMs is simple: If you had to buy one of these rookies today, who’s your pick?

Schaefer’s Start Is Breaking the Rookie Template

Historic production from the blue line

It’s hard to overstate how unusual Schaefer’s start has been for an 18-year-old defenseman.

According to NHL.com’s Rookie Watch and EDGE tracking data, Schaefer:

• Leads all NHL rookies with 15 points (7G, 8A) in 19 games.

• Leads all NHL defencemen in goals (7).

• Ranks first among rookies in power-play goals (4) and average ice time (22:34).

• Has already logged 27:40 in a single game, the most by an Islanders teenager since TOI tracking began in 1997-98.

• Has scored three goals from long range, putting him in the same club as John Carlson, Josh Morrissey and Brandon Montour in terms of bombs from distance.

He’s also rewriting the age-based record book. Schaefer became the youngest player in NHL history to score an overtime goal (18 years, 70 days), breaking Sidney Crosby’s mark, and the youngest defenceman ever to record a multi-goal game. NHL+2NHL+2

For a franchise that has spent years searching for a legitimate No. 1 defenseman, this isn’t just a nice story — it’s a potential organizational pivot.

The EDGE data: Skating, workload, and shot profile

The tracking data backs up the eye test. Using NHL EDGE:

• Schaefer leads all NHL defencemen in 20+ mph speed bursts and ranks among the league leaders in 22+ mph bursts.

• He consistently hits the three-mile mark in skating distance and leads all Islanders skaters in total distance covered.

• He’s near the top of the league in shots on goal from high-danger, mid-range and long-range zones.

In other words: this isn’t a sheltered, second-pair guy racking up easy power-play points. Schaefer is playing hard minutes, driving offense from everywhere on the ice, and still tilting the numbers.

Fantasy and dynasty angle

From a fantasy perspective, Schaefer is already in the conversation with names like Makar and Fox in terms of pure upside:

• Redraft leagues: He’s a must-own in any league that rewards power-play points, shots on goal, or offensive categories from defensemen. His usage suggests this pace is sustainable unless the wheels completely fall off on Long Island.

• Dynasty/keeper: If you’re in rebuild mode, this is the kind of profile you cash in for — 23-minute defencemen who can legitimately challenge for the Calder as teenagers are extremely rare.

Ryan Leonard: The Coach’s Dream Power Winger

Boxscore production plus real-world impact

Leonard’s counting stats don’t pop the same way as Schaefer’s — at least not yet. But context matters.

Through 18 games with Washington, Leonard has:

• 8 points (3G, 5A) in a middle-six role.

• 27 hits, ranking sixth among Capitals forwards.

• An average of 12:47 of ice time, with second-unit power-play looks.

• A 57.1% on-ice goals-for share at five-on-five, which is excellent on a team that still has its share of ups and downs.

Coach Spencer Carbery has gone out of his way to praise Leonard’s readiness, calling him one of the few 20-year-olds he doesn’t feel the need to protect. That’s rare language from a modern NHL coach and lines up with his usage on a line with Connor McMichael and Hendrix Lapierre, where Leonard is trusted to forecheck, win pucks, and still finish plays.

The development track: WJC dominance and NCAA scoring

None of this came out of nowhere. Before turning pro, Leonard:

• Put up 30 goals and 49 points in 37 games during his sophomore season at Boston College.

• Captained Team USA to gold at the 2025 World Junior Championship, recording 10 points (5G, 5A) in seven games and earning tournament MVP honours.

• Built a reputation in the USNTDP as a winger who could drive a line with his shot, physical play, and ability to get inside on defenders.

When you layer that track record on top of his current NHL usage and impacts, the picture that emerges is of a player who could realistically become a long-term top-six power winger with strong multi-category value.

Fantasy and dynasty angle

Right now, Leonard is the classic under-rostered rookie:

• In redraft leagues, he’s often stuck in the 10–20% ownership band because the raw points aren’t eye-popping yet.

• But in hits + scoring formats, he’s already doing enough to be worth a roster spot — and his ice time has room to grow if he keeps earning trust.

• In dynasty, he’s the type of player you grab before everyone else realizes that the coaching staff treats him like a 24-year-old veteran.

In your fantasy hockey hidden gems article cluster, Leonard fits perfectly as a “Category League Cheat Code” — a winger who can help in goals, assists, hits, and maybe power-play production as the season goes on.

Schaefer vs. Leonard: How Do You Choose?

Different shapes of value

From a pure value standpoint, Schaefer and Leonard offer very different things:

• Schaefer is a potential Calder front-runner and already sits in the top tier of fantasy defensemen. You’re betting on a historic rookie season and Norris-level upside down the road.

• Leonard is more of a multi-cat engine — a player whose points might be modest in Year 1, but whose hits, usage and five-on-five impact make him incredibly valuable in deeper formats.

In points-only or shallow leagues, Schaefer is the easy call. In banger leagues or very deep formats, there’s a universe where Leonard closes the gap faster than people expect, especially if he earns more power-play time.

Risk profiles

It’s also fair to consider risk:

• Schaefer is being asked to do a lot, very quickly. Heavy minutes for teenage defensemen can be a grind; if the Islanders wobble, his plus-minus or on-ice results could take a short-term hit, even if the talent is undeniable.

• Leonard’s risk is more role-driven. If Washington leans into a more veteran-heavy top six or changes its power-play configuration, he could get stuck around the 13-minute mark and 35-point pace for a while.

From a trade or keeper standpoint, Schaefer is the asset with the higher perceived league-wide value, but Leonard may be easier to acquire in fantasy and still has legitimate breakout potential.

What This Means for the Calder Race – And For You

Schaefer’s pace and record-chasing exploits put him near the top of most early Calder Trophy boards, alongside Demidov and a few other high-end rookies. Leonard likely sits a tier below in terms of awards odds, but that doesn’t mean he’s less valuable to his team.

For the Islanders, Schaefer looks like the franchise defenceman they’ve been missing since the prime of their last great blue-line core. For the Capitals, Leonard is exactly what they need in a transitional era: a young, physical winger who can grow into the next generation alongside whoever eventually replaces Nicklas Backstrom down the middle.

For fantasy GMs and poolies, the question is less about trophies and more about timing:

• Do you pay full sticker price for Schaefer now and hope he sustains this historic pace?

• Or do you quietly acquire Leonard before the hits + points combo becomes mainstream and the price jumps?

There’s no wrong answer — but there is an edge to be found by choosing the rookie who best fits your league’s scoring and your team’s timeline.
