Fantasy Football Dynasty Rankings (December 2025)

Dynasty Rankings Trending Upward 

Michael Wilson, WR, Arizona Cardinals (+145)

Previous rank: 256
Current rank: 110

Back in 2023, the Arizona Cardinals took a chance on a young receiver out of Stanford with the 94th overall selection in the third round. Back then, Michael Wilson went viral, telling anyone who would listen that the Cardinals got the  “Steal of the Draft.” Until recently, Wilson hadn’t really backed that statement up.

With Marvin Harrison Jr. sidelined, Jacoby Brissett has maximized Wilson's opportunities. From Week 11 through 15, Wilson led all fantasy receivers with 23.1 points per game. He topped 16 points in four of five games, with two games above 33 points, showcasing a sharp improvement in both target share and high-ceiling performance during Brissett's run as quarterback.

Wilson’s production has been directly tied to Brissett, who has finished as a top-12 fantasy quarterback in nine straight contests heading into Week 16. Now, in those five previous contests before Week 16, Brissett has peppered his targets. Trey McBride is second in the NFL over that period with 52 targets, while Wilson, once again, leads the way with an astonishing 67. For those keeping track at home, that averages out to 13.4 targets per game.

Wilson's jump in production is closely tied to his high-volume role. He converted 67 targets into 44 receptions for 535 yards during the stretch—demonstrating growth in both reliability and efficiency. His 50.8% air yard share and 803 total air yards show untapped upside if he can improve on his catch conversion rate.

When a receiver is being targeted as heavily as Wilson has been and then been as productive as he has been, we are talking 11.84 yards per target, 16.44 yards per reception, and 4.97 yards per route run, you are going to climb the fantasy charts in a hurry.

Kyle Monangai, RB, Chicago Bears (+60)

Previous rank: 153
Current rank: 93

Entering Week 16, Bears rookie running back Kyle Monangai had churned out 681 rushing yards on 146 carries. Only Quinshon Judkins (805), TreVeyon Henderson (773), and Ashton Jeanty (700) have been more productive runners as rookies than the seventh-round selection out of Rutgers.

From Week 9 through Week 15, Monangai has quietly made his presence known in fantasy circles as a solid flex option, averaging 12 fantasy points per game, while his running mate D’Andre Swift garners many of the headlines with his 13.4 fantasy points per game over that same seven-game sample. During the one game Swift missed over that period, Monangai dropped 22.8 fantasy points on the Bengals when he ran for 176 yards on 26 rushing attempts and hauled in three passes for 22 receiving yards.

As the Bears continue their push towards the postseason, the expectation is that the touches will begin to tilt towards the veteran, Swift. That said, Monangai has done enough to justify his fantasy ascension and, regardless, offers fantasy managers flex appeal with RB1 upside. When Chicago decides to move on from Swift, they have their next bellcow back in the waiting. Until then, we’ve seen both Monangai and Swift each produce with the other on the field. Back in Week 13, the Bears duo each topped 100 yards on the ground, becoming the first pair of Bears running backs to do so since Walter Payton and Matt Suhey accomplished the feat in 1985.

Blake Corum, RB, Los Angeles Rams (+66)

Previous rank: 187
Current rank: 121

In the three games between Week 13 and Week 15, did you know that Blake Corum is the RB8 in fantasy, averaging 17.8 fantasy points per game in PPR scoring formats? The Los Angeles Rams offense has been so proficient over that period that they have supported two fantasy running backs inside the top 10, as Kyren Williams has been almost as productive, averaging 17.6 fantasy points per contest over that three-game period.

Everyone has been waiting for the changing of the guard in the Rams' backfield since Los Angeles used a third-round pick on the former Wolverine back in 2024. It’s easy to see why fans and fantasy managers would like to see more Corum, as he has averaged 5.5 yards per carry this season. In fact, in the two contests before Week 15, Corum had topped 10.5 yards per carry in each; not that Week 15’s performance and 6.5 yards per carry were bad, it’s just Corum has been running the ball that well.

Looking more closely at the recent three-game stretch, the Rams' backfield has been relatively split in terms of touches and production, which bodes well for Corum's dynasty outlook. Over that span, Williams leads the way with 41 rushing attempts and 234 rushing yards (5.71 yards per carry), while Corum has produced 280 yards on the ground on 30 carries (9.33 yards per carry). Further to Corum's rushing efficiency, 16.7% of his runs have resulted in gains of greater than 15 yards, with 50.4% of his total rushing yards coming as a result of these explosive runs.

In fantasy, we love touchdowns, and while Williams has earned 57.1% of the Rams' touches inside the five-yard line, Corum has secured 42.9% of those touches along with an 83.3% rushing success rate and a 13.3% touchdown rate.

Other Notable Risers: Chris Rodriguez Jr. (+98), John Metchie III (+59), Tank Dell (+44), Sean Tucker (+41), Adonai Mitchell (+35), Darnell Washington (+35), Chimere Dike (+33), Matthew Stafford (+31), Wan’Dale Robinson (+30), George Pickens (+24), Woody Marks (+21), Jakobi Meyers (+17), Brock Purdy (+15), Cam Ward (+14), Kyle Pitts Sr. (+11)

Dynasty Rankings Trending Downward

Alvin Kamara, RB, New Orleans Saints (-20)

Previous rank: 98
Current rank: 118

We’ve all heard it before: Father Time comes for us all, and he’s undefeated. A running back's shelf life in the NFL is short to begin with; even the elite backs play declining around the time they transition into their 30s. Alvin Kamara was drafted in 2017, and in July, the Saints' All-Pro ball carrier turned 30.

Heading into Week 16, Kamara’s status is once again questionable (ankle/knee), having missed the three previous contests due to injury. However, even before suffering his latest injury, Kamara wasn’t exactly an option fantasy managers were able to trust every week.

From Weeks 7 to 12, Kamara dropped to RB50 status, averaging just 6.2 PPR points. He managed only 3.27 yards per carry and a modest 35.5% rushing success rate. His explosive run rate fell to 2.1% and his 1.79 yards after contact per attempt ranked just 79th, signaling pronounced drop-offs in his once-elite skill set.

Patrick Mahomes, QB, Kansas City Chiefs (-18)

Previous rank: 43
Current rank: 61

Patrick Mahomes' season came to an abrupt halt when the future Hall of Fame signal caller went down in Week 15 with a torn ACL. Now, this is far from the end, as the NFL has a funny way of telling its stories. Like Mahomes, Tom Brady had won three Super Bowls, tore his ACL in his ninth season, while his team also missed the playoffs that season. We all know what Brady did after he tore his ACL, and if the NFL script runs true, Mahomes will be back better than ever.

After a couple of seasons, when those in the fantasy street questioned whether or not Mahomes could still be a top-5 fantasy asset at the quarterback position, Mahomes went out there and averaged 21.1 fantasy points per game. That said, fantasy football is all about what you’ve done lately, and often players' fantasy value deteriorates once they slide out of the picture.

Another red flag for Mahomes and his fantasy value lies in the decisions that Travis Kelce will need to make in the offseason. Could the end of an era be near? Even before the 2025 season, there were doubts as to whether or not Kelce was going to return to the fold after yet another long season.

Unlike the running back position, quarterbacks can seemingly play forever. Aaron Rodgers has his team in the midst of a playoff hunt, and Philip Rivers returned to the league at 44 years of age after being named a Semi-Finalist for the Hall of Fame.

David Njoku, TE, Cleveland Browns (-30)

Previous rank: 107
Current rank: 137

There will be plenty of offseason talks in Cleveland as to whether or not the Browns should bring back David Njoku for a 10th season.

Not only has Njoku missed several games over the past two seasons, but the emergence of rookie tight end Harold Fannin Jr. has made Njoku expendable. Looking at the two tight ends' head-to-head numbers, it’s not even close when assigning value to the position. Njoku has a 53.6% route participation, accounting for an 8.8% air-yard share, a 10.5% target share, 44 targets, 33 receptions, a receiving-market share of 12.2%, and a 1.14 yards-per-route run rate.

As for the rookie, in the same statistical categories, Fannin has earned a 67.6% route participation, an 18.8% air yard share, a 20.1% target share, been targeted 97 times, caught 66 passes, resulted in a receiving market share of 24.7%, and earned a 1.81 yards per route run rate. People lie, numbers don’t, and the numbers here are damning and suggest Njoku’s future in Cleveland is uncertain.

Other Notable Fallers: DeAndre Hopkins (-38), Elic Ayomanor (-33), Chig Okonkowo (-30), Keenan Allen (-29), Rachaad White (-29), Keon Coleman (-27), Mark Andrews (-26), Joe Mixon (-24), Tua Tagovailoa (-23), Jayden Reed (-21), Isaiah Pacheco (-20), Tony Pollard (-16), Isaiah Likely (-16), Brandon Aiyuk (-12), Derrick Henry (-12), Breece Hall (-8), DeVonta Smith (-7), Travis Kelce (-7), Brian Thomas  Jr. (-6), Garrett Wilson (-5)

Dynasty Fantasy Football Trade Value Chart

Name to Know

Gunnar Helm, TE, Tennessee Titans (+47)

Previous rank: 259
Current rank: 212

I went back to my notes for this one. This past April, the Tennessee Titans selected Gunnar Helm out of the University of Texas, where the former Longhorn was coming off a 786-yard receiving season in which he caught seven touchdown passes while sharing targets with the likes of Matthew Golden and Isaiah Bond.

In my post-draft analysis, I talked about Helm as one of the smoothest athletes in this draft, but fantasy managers would need to remain patient, as the Titans offense would go through some trials and tribulations under rookie quarterback Cam Ward. Through the first seven weeks of the season, that analysis held. Helm was the TE41 in fantasy points per game, averaging 4.6, while Chig Okonkwo led the way with an average of 6.4 fantasy points per contest.

WARD TO HELM FOR 34-YARD TD!

TENvsSF on FOX/FOX Onehttps://t.co/HkKw7uXVnt pic.twitter.com/6wK6aJe4L1

— NFL (@NFL) December 14, 2025

Fast forward to the end of the season and between Week 11 and 15, Helm has been targeted on 29% of his routes, second most among tight ends, resulting in 8.5 fantasy points per game (TE19), putting hoim in the same conversation as Jake Ferguson (9.2), T.J. Hockenson (8.9), Juwan Johnson (8.6), and Theo Johnson (8.4).

Over that most recent five-game span, Helms' usage in the Titans offense has mirrored Okonkwo's, with Okonkwo running 107 routes, averaging 4.0 targets per game, and accounting for a 12.5% air yard share and a 20.3% team receiving market share. For Helm, he’s run 83 routes, earning 4.8 targets per contest, an 11.2% air yard share, along with an 18.2% team receiving market share. The biggest difference is that Helms' 1.93 yards per route run is impressive in comparison to Okonkwo’s 1.66 yards per route run.

Maximize Return

Christian Watson, WR, Green Bay Packers (+49)

Previous rank: 154
Current rank: 105

Stop me if you have heard this before: Christian Watson was questionable heading into Week 16. Watson entered the season on injured reserve and, as a result, had only played in eight contests as the Packers entered their Week 16 showdown with the Chicago Bears.

The talent has never been a question when talking about Watson; it’s durability and dependability that have hampered Watson’s fantasy value since entering the league in 2022. The truth is, Watson has yet to play a full slate of games since the Packers drafted him, and he has missed 19 games in his nearly four-year NFL career.

Now, if you have a league in which managers don’t see availability as important as I do in fantasy, then you have yourself a dancing partner for trade talks. Watson is actually a pretty easy sell this holiday season, as he has been productive since returning to the lineup. Since Week 11, Watson has averaged 15.9 fantasy points per game, which ties him with Courtland Sutton as the WR15 over that five-game span.

Watson’s 293 yards receiving ranks 19th in the NFL while accounting for a 27.4% Packers receiving market share. Jordan Love has also been looking for Watson deep, targeting 20 or more yards down the field on 10 occasions (second-highest) over those five games, assisting in Watson’s 521 air yards and 35.3% air yard share. The Packers pass-catcher earned a 14.65 yards per route run rate, which is the 13th highest among receivers who have run at least 100 routes.

Buy the Dip

Rome Odunze, WR, Chicago Bears (-15)

Previous rank: 21
Current rank: 36

Before the Bears went into their Week 5 bye, Rome Odunze was tearing the league up, averaging 19.9 fantasy points per game and was the WR3 in fantasy. However, fantasy football is a cruel mistress, and since the bye, Odunze has averaged just 8.3 fantasy points (WR52) and has averaged a mere 5.7 fantasy points (WR77) in his last three games in which he had suited up before Week 16’s contest against the Packers.

For those looking to buy, now is the time. Shortly before the kickoff to Week 15’s action, Odunze reaggravated his foot injury, and with the timing of the whole thing, many managers may not have had time to react, further compounding their frustration regarding the second-year receiver. Savvy managers know the key to fantasy football is to remove the emotion from everything.

As Odunze continues to miss time with that foot injury, and as long as DJ Moore continues to produce in Odunze’s absence, Odunze will continue to deteriorate as a fantasy asset. Right or wrong, out of sight, out of mind.

The hometown kid 🙌

What is important is to take the value of a receiver who had a 42.0% air yard share and 435 air yards through his first four games. Take a chance on a receiver whose upside includes a 24.8% target share who is capable of seeing 8.3 targets per game when healthy. Young stud receivers don’t come along very often, and if you can acquire Odunze for a first-round pick in 2026, you would be doing your dynasty rosters an disservice if you didn’t explore that opportunity.
