Dynasty Trade Value Chart: September

The long wait is almost over. The 2025 NFL season kicks off in just two days, and with it comes the end of speculation and the beginning of real answers. Writing the September edition of the Dynasty Trade Value Chart always feels a little strange because so much of what we think we know about player values is about to be tested on the field. Some players will confirm the hype, others will disappoint, and within a few weeks, the dynasty landscape will look very different from what it does today.

This month's article is built to prepare you for that transition. At each position, I'll focus on three key areas:

1. The biggest storyline to watch early in the season.
2. The players whose dynasty value shifted the most over the last month.
3. The players I'm personally buying and the reasons why.

By the time Week 1 is in the books, values will start moving fast. This article will help you stay ahead of those changes and identify where the opportunities are before your league mates catch on.

Quarterback

Top Storyline: Sophomore QB Performance

If you look at the consensus dynasty rankings on KeepTradeCut (a site that measures market sentiment), six of the top 19 quarterbacks come from the 2024 rookie class. We are in unprecedented territory with so many quarterbacks from one class ranked so highly. By the end of September, we'll have some important new data points on whether these young passers are worthy of such lofty status.

• Will Jayden Daniels and Bo Nix continue to ascend after strong rookie seasons, or will they stumble in Year 2 the way C.J. Stroud did?
• Can Caleb Williams and Drake Maye take the next step after showing flashes as rookies?
• How will Michael Penix Jr. and J.J. McCarthy perform now that they are expected to see their first extended action?

We know what to expect from most of the established dynasty quarterbacks. It's this 2024 group that remains the big wild card. With many of the elite options approaching age 30, whichever of these young quarterbacks separates themselves could quickly climb to the top of the dynasty rankings. At the same time, history suggests that not all of them will hit. Some dynasty managers who drafted these players as long-term cornerstones in Superflex formats may soon be left holding the bag.

Big Movers

As a reminder, you can find my reasoning for ALL value changes on the Change Log tab of the Dynasty Trade Value Chart tool. I'll highlight a few of the more notable quarterback adjustments here. Overall, there weren't many dramatic shifts, which makes sense given how few true quarterback competitions played out this summer.

Jaxson Dart – His value jumped after multiple impressive preseason outings. You get the sense from head coach Brian Daboll and others around the Giants that they feel confident they have finally found a long-term successor to Eli Manning. Whether that proves true won't be decided on a few preseason drives but on 30-plus regular-season starts. Still, this was a highly encouraging beginning.

Anthony Richardson Sr. – His situation has been a roller coaster. After the Daniel Jones signing, Richardson was still viewed as the heavy favorite to start. Following rough OTAs and another injury, momentum swung to Jones. Then, as the camp battle evened out, the expectation returned to Richardson. Logically, if it's close, you go with the high-upside Top 5 pick. Yet in the end, Jones was announced as the starter, and head coach Shane Steichen made it clear that the decision was for the entire season. The takeaway is that the people in the building with Richardson every day don't fully trust him yet. He told on himself when he said, "I can't be slacking anymore."

Players I'm Buying

Here are some players I am buying. Please note that the positional ranking in parentheses is the consensus valuation according to KeepTradeCut. 

Jared Goff (QB21) – My hunch is that Detroit's run game takes a small step back after some offensive line losses, but the passing attack picks up the slack. You can argue that no quarterback has a better group of weapons. With Amon-Ra St. Brown, Jameson Williams, Sam LaPorta, Jahmyr Gibbs, and Isaac TeSlaa all on the field, defenses will be stretched thin. In Superflex leagues, Goff is the perfect QB2, giving you steady production at a reasonable trade cost.

Michael Penix Jr. (QB19) – Losing RT Kaleb McGary for the season is a concern, but I'm still betting on Penix's talent. He has a real chance to break out in 2025, and the fact that he'll play more than 10 games a year indoors for the foreseeable future adds to the appeal.

Daniel Jones (QB30) – If you're contending in Superflex, having three starting quarterbacks is a must. You need the bye-week coverage, and you don't want one injury to sink your season. Jones is the cheapest quarterback available who offers both realistic QB2 production in 2025 and a chance to hold a starting job beyond this year.

Running Back

Top Storyline: Veterans Starting Fast

Over the full 2025 season, the rookie running back class will likely be the biggest story. This group has the talent to reshape the dynasty landscape the same way the 2024 wide receiver class impacted the top of the rankings at their position. The full impact may take time to materialize, though. Rookie backs often need a month or more to earn a full workload, while veteran runners typically start hot before fading down the stretch.

That creates a short-term "sell high" window on top veterans. Saquon Barkley is currently valued above every rookie back except Ashton Jeanty, and if Barkley opens the year strong, you can command a massive return. The same goes for veterans like Derrick Henry, Alvin Kamara, Christian McCaffrey, and James Conner, all of whom could see their dynasty value peak in September. If you have one of these aging backs, decide quickly whether you're a contender. If not, be aggressive about moving them early in the season while the market is still hot. Perhaps you can move one for one of the talented rookies who starts more slowly than expected.

Big Movers

This is the position where we saw the most substantial value changes over the past month.

Breece Hall / Braelon Allen – Hall's redraft ADP slid almost two full rounds (from Round 3 to Round 5), while Allen's climbed from Round 15 to Round 10. The short-term gap is still significant, but it's shrinking fast. That same narrowing is reflected in their dynasty values.

Tyrone Tracy Jr. / Cam Skattebo – Many expected Skattebo to beat out Tracy for the starting role. Instead, injuries kept him from making a push, and he may even open behind Devin Singletary. Tracy's stock is rising, while Skattebo's has taken a hit.

Jacory Croskey-Merritt – He has gone from an intriguing fourth-round rookie pick to a player worth a second-round rookie selection in any late drafts. If you drafted him, you're probably getting lowball offers (I received an offer of Antonio Gibson for Croskey-Merritt just yesterday). If you didn't draft him, you're likely seeing offers in your inbox trying to get you to buy for exorbitant prices (no, I am not trading a 2027 1st for him). I did trade a 2026 second (projected late in the round) straight up for Croskey-Merritt, and that feels like a fair valuation if dynasty managers really are trying to get a deal done here.

Players I'm Buying

Here are some players I am buying. Please note that the positional ranking in parentheses is the consensus valuation according to KeepTradeCut. 

Kyle Monangai (RB61) – I've been targeting Monangai in the third or fourth round of rookie drafts and as a throw-in piece on bigger deals. While Chicago beat writers haven't confirmed his role, many signs point to him as the No. 2 back. That uncertainty has kept his profile lower than many other Day 3 rookies, but the upside is real. Ben Johnson has consistently used a two-back committee, and his power backs have regularly found the end zone. 

Kendre Miller (RB71) – Rookie Devin Neal has drawn plenty of attention, but Miller quietly secured the backup job behind Kamara with a strong offseason. Expect him to have a bigger role than many anticipate, especially if the Saints manage Kamara's workload more than they did in 2024.

Keaton Mitchell (RB55) – Mitchell is stuck as RB3 behind Derrick Henry and Justice Hill, which means his price won't rise soon. That makes this the time to buy. He's an explosive young back who could deliver league-winning upside if an opportunity eventually opens.

Jaylen Warren (RB39) – Warren just signed a two-year extension keeping him in Pittsburgh through 2027. He has been running ahead of Kaleb Johnson all camp, and there's a real chance he fills the James Conner role while Johnson slides into a complementary spot like Trey Benson once did. Not every third-round rookie running back displaces the veteran and I am not sure the possibility of Warren holding onto the lead role has been fully priced into his dynasty valuation.

RJ Harvey (RB18) – While rookies like TreVeyon Henderson and Omarion Hampton have surged in value, Harvey has held steady. Concerns about a split backfield with J.K. Dobbins are fair, but my bet is that Harvey becomes a 15-to-20 touch per game back sooner than most expect. If and when that happens, good luck trying to trade for him.

Braelon Allen (RB32) – Don't rule anything out, but it feels like the Jets plan to move on from Breece Hall after this season. The new regime appears to love Allen, and it wouldn't surprise me if he pushes for a near 50-50 split in 2025 before taking over as the lead back in 2026.
