IDP Dynasty Report: Stock Up, Stock Down
With the halfway point of the 2025 NFL season upon us, Jase Abbey examines which IDPs have seen their dynasty stock rise... or take a massive hit.
We’re only eight games in, but even in the slower pace of dynasty formats, IDP values have swung harder than Tariq Woolen trying to land an open-field tackle.
This Stock Up/Stock Down report breaks down whose dynasty arrow is really moving as we hit the midseason mark. No rookies this time; their moment’s coming soon in a separate deep dive. For now, it’s about the players you thought you already knew and whether their dynasty value is climbing or slipping away.
We’ll give you one stock up and one stock down at LB, DL, and DB. As always, hat tip to PFF for alignment data, and tackle, pressure, and win rate numbers.
Linebacker: Stock Up
Nakobe Dean, LB, PHI: Dynasty LB25
Vic Fangio has a lot to answer for. First, he muddied the waters by talking up how excited he was about Jihaad Campbell’s hybrid off-ball/pass rusher talents. He then got us excited by using Campbell as an off-ball linebacker. Finally, just when we thought we had a fix on the situation, he pulls the rug completely—not only by using the rookie on the edge (and not as an edge rusher) but also by killing his snap share by replacing him with Nakobe Dean. Eurgh.
Campbell’s loss is Dean’s gain, and not just for what seems like the rest of the year, but beyond. We knew Dean could play, based on his 2024 breakout year before tearing his patellar tendon in the Wild Card round, but the concern was that he wouldn’t see sufficient snaps to showcase his talent or prove to wherever he lands in free agency next year that the injury hasn’t had any long-term effects.
It’s too early to say we can put those concerns to bed entirely, but the early signs are promising. Hopefully, you grabbed him from waivers a few weeks back. If not, add or trade for him if you can.
Linebacker: Stock Down
Daiyan Henley, LB, LAC: Dynasty LB9
After bursting onto the scene in 2024, Daiyan Henley was considered a consensus top 10 linebacker in dynasty formats. He had just finished as the LB12 or better among off-ball linebackers (Big3 scoring), finished with a 14.2% tackle efficiency ratio, and was clearly locked in as the sole full-time linebacker. Moreover, with Jesse Minter returning as the Chargers’ DC, we had the warm fuzzy feeling that there were unlikely to be wholesale changes in his role or production.
We were right about his role, but couldn’t have been more wrong about his production. Through eight games in 2025, Henley has performed at a far inferior level—especially in pass coverage—and has mustered a tackle efficiency ratio just shy of 9.7%. After managing only three or more solo tackles in only two games of his eight games, Henley has left IDP managers scratching their heads.
Jeff nails the Henley situation on this week’s episode of The IDP After Show.
It’s difficult to provide a definitive answer as to what’s going on. Yes, Henley is playing a higher percentage of snaps on the edge (although not as a pass rusher), which is never great for tackle production. Granted, he had the flu for a game, too. But these points don’t entirely justify the degradation in his performance and production over half a season.
What works in Henley’s favour is that there’s nobody better on the roster. Troy Dye can’t cover, Denzel Perryman can’t do much of anything, and Junior Colson is never healthy. So, hold him, for now, but pay close attention to how he performs the rest of the way and any comments coming from the Chargers front office.
(Note: Much of what we said here also applies to the Bills’ Terrel Bernard.)
Defensive Line: Stock Up
Byron Young, EDGE, LAR: Dynasty EDGE15
There’s something in the water in Los Angeles, as Byron Young has progressed from a good-but-not-great edge rusher into becoming excellent overnight. He improved from year one to year two, but the jump to year three is on a whole different level.
In 2024, he had a pedestrian 11.8% pressure rate, and his 13.3% win rate impressed nobody. But it’s not like anyone cared much, provided he continued to play a ridiculous amount of snaps (top 10 among all edges).
As it turns out, that production was his floor. Through seven games in 2025, the 27-year-old has produced pressures on 15.2% of his pass rush attempts, beaten blockers 26.9% of the time, and the results speak for themselves: nine sacks, third-most in the league and more than double that of his higher-profile teammate Jared Verse.
As the guys pointed out in the video above, we should temper expectations that Young can keep up this pace, but that doesn’t mean it’s not time to at least adjust expectations. There are not many players who can produce his tackle volume and production as a pass rusher.
Defensive Line: Stock Down
Quinnen Williams, DT, NYJ: Dynasty DT5
There were more obvious names to pick here, but I wanted to focus on Quinnen Williams because he’s too talented for this to make sense. And I can’t be the only IDP manager scratching my head over how far things have slipped.
The lone sack isn’t the worry. It’s the trend of three straight years of decline in the areas that previously made him such a valuable DT in IDP.
Both of the 2025 figures in that chart are Williams’ lowest since his rookie year in 2019. To his credit, Williams’ tackle rate has spiked this season, and that’s kept his fantasy line somewhat respectable. But in dynasty terms, his stock’s still sliding until we see signs of a rebound as a pass rusher.
A dysfunctional defense can drag down even the best, and he’s spent less time lined up over the tackle than in years’ past, but neither of those points fully explains what we’re seeing.
If the trade rumors prove true, a move might be exactly what Williams needs to reset and remind everyone what he can still be.
For those out there who believe he’s unlikely to rebound, it might be an opportunity to sell. For those of us who believe he can and will improve, now’s the time to buy.
Defensive Back: Stock Up
Talanoa Hufanga, S, DEN: Dynasty S28
If you can turn the other cheek to the “dirty player” accusations (and why wouldn’t you from a fantasy perspective), there are few defensive backs whose dynasty stock has risen quite like Talanoa Hufanga’s. He’s like a man reborn in Denver, where Vance Joseph has got him playing at a level reminiscent of that excellent 2023 season we all remember so fondly.
More pass breakups and interceptions would really push his value into the elite tier, but we know he’s capable of those and that they will come in time. In the meantime, and crucially, he’s producing in ways that are more stable. His tackle efficiency is healthy, sitting in the 77th percentile among all defensive backs.
Hufanga’s performance and deal—which runs through 2027—suggests he has a good chance to remain a solid fantasy DB for years to come. He’s just got to stay healthy for a change…
Defensive Back: Stock Down
Kerby Joseph, S, DET: Dynasty S37
If your league uses big play scoring, Kerby Joseph has been a difference-maker after recording an interception every other game over his last 20 starts. Unfortunately, despite very little change in his role from last year—when he finished with 90 tackles—he’s in the 9th percentile among all safeties AND cornerbacks in 2025.
It doesn’t help that he’s missed more than 27% of his tackle attempts, but even if he had made every one, his tackle production would still be abysmal.
It’s easy to know what to do with a player like this. Without getting into too much detail, if he’s scoring well in your league, keep him. If not, sell or replace him.
Final Thoughts
Eight games are not sufficient to make a definitive conclusion about a player’s dynasty value, especially when that player’s larger body of work suggests recent trends might be an anomaly.
With that in mind, take these as what they are: recommendations, not absolutes. Your scoring system might swing things one way or the other. Hopefully, there’s enough context here to help you arrive at your own conclusion.

This is solid. Someone I am buying is Hines-Allen. He is getting the pressure, and the sacks should come soon and the Hines-Allen manager may be impatient.
Herbig is another buy/hold for me for 2026 and beyond.
I think I would sell Burns and Young. They are playing so well. But I doubt there value gets any higher, and I'd be happy to cash out and get some of their value in the forms of picks.
