Darren Raddysh is the exception, not the rule. He's not what we are looking for. A 30-year-old defender launching from 1.32 fantasy points per game to 2.29 fantasy points per game happens about as often as a leap year. What we are after is what happens more often. We are leaning into the "usual."
As in, usually "a defenseman has played X number of games and are usually X years old when they start to contribute to fantasy hockey."
Here's the quick line to what I'm defining as "usual."
The median fantasy points per game (FPPG) across the 1,020 individual top-60 defense seasons since 2009-10 is 1.89, so that's the bar we set for a breakout.
Using all game logs since the 2009-10 season, there are 162 defenders that have made more than one appearance among the top 60 for fantasy scoring. This purposefully excludes any one-time flukes.
Of those 162 defenders, 98 made their debut in 2009-10 or later, meaning we have complete game logs for their entire career.
Of those 98 defenders, 73 eventually held a rolling 41-game FPPG average above 1.89 for at least 41 consecutive games -- a half-season at that pace at minimum, and often longer.
The average age those 73 blue-liners had reached when that breakout run began was 24 years, 248 days (with the majority doing it between 22 years, 330 days and 26 years, 266 days).
The average experience those 73 D had when that run began was 254 games played (with the majority doing it between 157 and 379).
So Raddysh is unusual.
He didn't make the list of 73 because he hasn't had multiple top-60 fantasy seasons. He will after this season, but that's not the point. The point is that only a half a dozen D-men since the 2009-10 season have burst onto the scene when they are as old as Raddysh. By the numbers, we want to look for younger players when hoping for a breakout.
What's interesting though is when you consider the other half of the formula: Experience.
Raddysh has a career 249 games played, which is only five games shy of the "usual" breakout experience for the 73 defenders that made the breakout list. Age is important, but it clearly isn't the only factor. Raddysh didn't make his debut until he was 25 and didn't play his first full season until he was 27.
So we flip Raddysh's profile around. Instead of a player who arrived late and spiked out of nowhere, we're hunting the defenders sitting right in that pocket. Young enough that the breakout is probably still ahead of them, experienced enough that they're due. And to keep this list actually useful, I've thrown out anyone who's already posted a top-60 fantasy season on the blue line. We're not looking for guys who've done it before; we're looking for the ones who haven't done it yet.

The breakouts
Philip Broberg, D, St. Louis Blues (25.2 years old, 1.14 FPPG in 230 games played): Broberg is already a heavy-minutes, underlying-metrics darling and the only thing capping his fantasy value is a power play he's never truly run. With Justin Faulk now in Detroit, that quarterback job is finally open. Win it over Logan Mailloux and the 50-point breakout arrives; lose it and he's a multi-category floor play.
Jamie Drysdale, D, Philadelphia Flyers (24.4 years old, 1.23 FPPG in 295 games played): Drysdale took a step last season (32 points), got a new four-year deal for it, and opens 2026-27 quarterbacking Philadelphia's top power play. The 50-point ceiling is live if he seizes true top-pairing minutes. The recurring "if" is health, which has interrupted every prior run at a breakout.
Owen Power, D, Buffalo Sabres (23.8 years old, 1.39 FPPG in 323 games played): The former No. 1 pick has the pedigree and the minutes but keeps refusing to shoot, as he managed zero power-play points last season despite getting 75 minutes there. Power has shown he can play defense, the key will be him deciding to chip in on offense once in a while, too.
Luke Hughes, D, New Jersey Devils (23.0 years old, 1.39 FPPG in 223 games played): Even splitting the top power play with Dougie Hamilton, Hughes ranked 14th among qualified defensemen (minimum 1:15 per game) in power-play points per 60 last season -- elite rate production that just needs more time to become raw totals. Hamilton keeps it a committee, but the per-minute scoring says Hughes doesn't need the whole job to pay off.
Pavel Mintyukov, D, Anaheim Ducks (22.8 years old, 1.33 FPPG in 204 games played): Anaheim bet five years and $36 million on Mintyukov's upside, and a rising even-strength role should push him past 20 minutes a night with triple-digit blocks and shots. The catch is the power play. Jackson LaCombe owns the top unit, so unless Mintyukov pries it loose, his point ceiling stays capped and he's more floor than fireworks.
J.J. Moser, D, Tampa Bay Lightning (26.2 years old, 1.34 FPPG in 338 games played): Fittingly, Moser spent last season paired with the very same Darren Raddysh from our intro, the two forming one of the NHL's stingiest shutdown duos. He'll get to run it back this year as the shutdown side of the top pairing with either Victor Hedman or John Carlson. The question now is whether he can layer the shot-blocking and hits from his Coyotes days back onto the big minutes and points he's found in Tampa.

Already broken out
These defenders already cracked the top 60 in a season, so they're not breakouts in the strict sense, but they sit right in the same age-and-experience wheelhouse as the names above. Several are still going under-appreciated on draft day relative to what they already produce. Consider them the safer, proven cousins of the bets we just made.
Bowen Byram, D, Chicago Blackhawks (25.2 years old, 1.46 FPPG in 331 games played): Byram's move to Chicago gives him a real shot at the offensive keys he could never fully hold in Buffalo or Colorado. Just know he'll have to hold off the young Blackhawks blue line for the power-play reps. The counting stats are proven, but the top-unit role isn't handed to him.
Mattias Samuelsson, D, Buffalo Sabres (26.5 years old, 2.01 FPPG in 292 games played): Ignore the shiny plus-41 that inflated last year's rate, it won't repeat, and it's an increasingly rare fantasy category anyway. The reason to roster Samuelsson is the floor beneath it, as he led the Sabres in blocked shots and ranked among their top hitters. This is the kind of every-night volume that quietly wins the peripheral categories a lot of managers punt.
Brandt Clarke, D, Los Angeles Kings (23.6 years old, 2.02 FPPG in 188 games played): Clarke is the youngest name here and the most complete offensive package. The 23-year-old is a legitimate power-play performer already producing at a top-tier rate, and now stepping fully out of Drew Doughty's shadow to run the Kings' back end as his own.
Simon Edvinsson, D, Detroit Red Wings (23.6 years old, 1.77 FPPG in 177 games played): Two of the 60 most physical seasons any defenseman 23-or-younger has posted since 2009-10 belong to Edvinsson, and he's played only two full ones, with his workload still climbing. He pairs with Moritz Seider, a star in his own right who tops that very list, giving Detroit a young shutdown tandem that already floods the hits-and-blocks columns; the points will follow as the minutes do.
Braden Schneider, D, New York Rangers (24.9 years old, 1.42 FPPG in 372 games played): Schneider turns up on that same list as Edvinsson -- one of the most physical young-defenseman seasons since 2009-10 -- which is the whole case for him: hits, blocks, and a quietly growing point total that add up to more than the zero fantasy buzz he gets behind the Rangers' bigger names. He won't win you a category, but he's the steady multi-cat piece that outproduces his draft slot.
