Here are your buys, sells, and sleepers for your contending roster for September 2026.

Buy

RB Josh Jacobs, GB

You are a contender. You aren't looking for production right now. You have that. You're looking at what will happen toward the end of the season, and no one has more late-season value than Josh Jacobs.

Jacobs is still on the commissioner's exempt list, and reports say he could be facing a four-to-six-game suspension. That uncertainty continues to keep his value low. He can be acquired for a 2028 second-round pick right now.

Whatever suspension Jacobs receives, the two games he has already missed will probably count toward it. That means Jacobs could return right around the start of the bye weeks and be available for the fantasy playoff run.

He'll be coming back to a team that doesn't have a clear lead rusher. MarShawn Lloyd has 23 carries this year and is averaging 3.0 yards per carry. Chris Brooks has 11 carries and is averaging just 3.64 yards per carry. Kaleb Johnson has finally gotten involved with 12 carries, averaging 3.2 yards per rush.

Jacobs can return to this team and immediately become the workhorse. The passing game has been good enough to move linebackers and safeties out of the box, creating running lanes for Jacobs.

You get a healthy workhorse running back at a discounted price. We've seen a ton of injuries already this year, and that will probably continue. Sometimes the fantasy champion is simply the team that stays healthiest. Add some health and volume for later in the season now, before Jacobs' value starts to rise.

Let's not forget that Jacobs rushed for 13 touchdowns in 15 games last season in this Packers offense. The season before that, he ran for 15 touchdowns. That's the kind of production you don't normally get this cheaply.

Sell

RB Kyle Monangai, CHI

Injuries have massive ripple effects across fantasy football. When Caleb Williams went down, there was dread not only on the faces of his fantasy managers, but also among anyone who rosters Colston Loveland, Rome Odunze, or Luther Burden III. Dynasty managers with D'Andre Swift and Kyle Monangai, while certainly not celebrating the injury, have to assume an increase in rushing opportunities with Caleb out.

That is exactly why you should be selling Monangai. His value is going to spike this week as managers try to figure out how the Bears offense will change in the Tyson Bagent / Case Keenum era.

I'm selling Monangai because we still have D'Andre Swift. He is still the lead back for the Bears, and it's not particularly close. Swift has out-snapped Monangai 93 to 57 over the first two weeks and has out-carried him 34 to 20.

Monangai has been efficient with his touches, averaging 7.35 yards per carry this season after averaging 4.63 last season. But volume is key, and he isn't seeing enough of it.

There was hope that Monangai would emerge as the pass-catching back, but he has seen only two targets in each week, while Swift saw one and then five. Monangai has essentially been a flex player unless he scores a touchdown. He has only two games with double-digit fantasy points, and both came when he reached the end zone.

This is dynasty, so maybe you think Monangai will take over next year. But Swift is under contract for the next three years, with at least next year seemingly secure because of the dead-cap hit.

You can sell Monangai right now for a second-round pick, or package him with a second- or third-rounder to move up and acquire a first. You can turn Monangai into a draft pick that helps you acquire that final piece later in the season, or turn him into a player who can help you secure wins now.

We don't currently know the severity of Caleb Williams' injury, and early reports indicate it may not be as bad as initially believed. Williams could miss at least four games, but he could also return sooner, while managers are pricing the players around him as though he's going to miss the entire season.

Selling at a high point is how you win in dynasty.

Deep Sleeper

RB Seth McGowan, IND

Jonathan Taylor isn't going anywhere contract-wise. He has a very team-friendly contract through the 2028 season. The Colts signed him to be the guy and the focal point of the offense.

The Colts are running the ball in part because of their lackluster passing game. Wide receiver Alec Pierce left the Week 2 game with a heel injury. Veteran signing Keenan Allen has a looming league suspension hanging over him. Tight end Tyler Warren and wide receiver Josh Downs have stepped up, but not enough to turn quarterback Daniel Jones into a superstar.

Expect the Colts to continue leaning on the run game. Taylor being the focal point is what concerns me.

Through two weeks, Taylor has 43 carries and seven receptions. That's coming off a season in which he had 323 carries and 46 receptions. He's only 27 years old, but he's already taken a tremendous amount of punishment throughout his career. How long can he hold up?

Whether it's because of an injury or simply a rotation, Seth McGowan is worth rostering right now.

DJ Giddens was a healthy scratch in Week 1 and is now dealing with a knee injury, giving McGowan the clear backup role.

As of Week 2, McGowan has only two carries and one target. You're rostering a handcuff and hoping something changes. He's available on waivers or for a last-round draft pick, so the cost is essentially nothing.

Even if McGowan were forced into the lead-back role, you're hoping we see Kentucky McGowan, not New Mexico State or Oklahoma McGowan. He's not a "league winner," but if given the opportunity, he could be a useful bye-week flex fill-in.

You can also flip McGowan later if his role increases and you don't need the production. Dynasty managers will likely overreact to a Taylor injury and overpay for McGowan. That's a situation where you want to be on the right side of the trade.

Contending in dynasty is where we all want to be, and you are there. Just because you're at the top of the standings right now doesn't mean you should rest on the team you drafted.
