Dynasty Fantasy Football Rankings: Overvalued, Undervalued Players (2025)

Kacey Kasem looks at overvalued and undervalued players for dynasty fantasy football. She examines two players currently being overvalued and two who are value picks.

Dynasty fantasy football rankings constantly shift, especially as we inch closer to the new season and fantasy drafts. Dynasty managers know the importance of finding those underrated players who could be steals in drafts or trades. They also know some players are overhyped due to unsustainable trends or past production.

I'll break down two overvalued players heading into the 2025 season, despite their past success. While they may have put up big numbers in the past, their current dynasty price does not align with their likely production in 2025. Additionally, I highlight two game-changers flying under the radar at the moment.

Whether contending, rebuilding, or just trying to make a trade, looking for value is crucial. Let's take a peek at the RotoBaller dynasty rankings to find some players you should be cautious about and those who could go beyond expectations in 2025.

Kyren Williams, RB, Los Angeles Rams (Overvalued)

Kyren Williams enters this season coming off an outstanding 2024 campaign. The running back set career highs, tallying 1,299 rushing yards and 14 touchdowns on the ground. The Notre Dame product handled 316 carries, a career-high in touches. It was also the most carries of any running back not named Saquon Barkley.

Despite his career year, Williams' dynasty outlook comes with some risk. Williams saw heavy usage in the run game last season but minimal involvement through the air. He caught just 34 passes for 182 yards and two scores on 40 targets. And ball security has been an issue for the RB, as displayed by his five fumbles last season.

In addition, 12 of Williams' 14 rushing touchdowns came from within the 5-yard line. He depends heavily on those close TDs, which means touchdown regression could happen, especially if the Rams mix in 2024 draft pick Blake Corum.

*This is NOT to rag on Kyren Williams*

Speed matters. Kyren did NOT score on this nice 30-yard run. The next few plays after this?

Corum's rookie journey led him to 207 rushing yards on 57 carries. Although those stats aren't eye-popping, he could see a second-year breakout in 2025. Even if Corum doesn't light it up, look for him to take some work away from Williams.

Additionally, wideout Cooper Kupp signed with Seattle, and the Rams brought Davante Adams in to fill the WR void. Adams is coming off a 1,063-yard season and will be alongside superstar Puka Nacua. There are a lot of capable mouths to feed in the end zone.

There is no debating that Williams was a noteworthy asset for dynasty rosters in 2024 (currently ranked on the RotoBaller dynasty rankings as WR11). He should continue to be a productive back for fantasy teams in 2025, but regression is likely. While his volume made him a fantasy phenom in 2024, his long-term dynasty value with the Rams is questionable. Williams is heading into his rookie deal's final year and is eyeing an extension.

Jaylen Waddle, WR, Miami Dolphins (Overvalued)

Jaylen Waddle heads into the 2025 season ranked as the WR21 on RotoBaller's dynasty rankings, ahead of teammate Tyreek Hill (WR33). Waddle has been a productive receiver in his NFL career, but his 2024 campaign was a step back. The former first-round draft pick is overvalued in dynasty leagues, and there are plenty of reasons to avoid the player.

Waddle finished his 2024 campaign with 58 catches on 83 targets for 744 yards and just two touchdowns. It was the former Alabama star's first time failing to reach 1,000 yards in his four-season career.

The Dolphins' offensive struggles, including quarterback Tua Tagovailoa missing six games, contributed to the wide receiver's decline. While Tagovailoa was active, he often struggled to get Waddle the ball in tight coverage. Additionally, the receiver dropped eight balls in 2024 and has only one season where he dropped under seven.

Lack of opportunities led to a career-low two touchdowns for Waddle. He drew just two targets within the 10-yard line and registered the fewest targets of his career (83).

The role of Hill on this offense also leads to too many question marks surrounding Waddle. Hill has displayed his frustrations with the Dolphins. If the Cheetah forces himself out of Miami, Waddle could return to the WR1 role. If the Cheetah stays, it will be difficult for the Dolphins to support high-end wide receiver fantasy production beyond Hill.

Moving Waddle to the WR1 role may not be an upgrade for the team. His dynasty value will quickly increase if he becomes the No. 1 receiver. You'd have to grossly overpay for him in that situation just to get a boom-or-bust player (just three double-digit performances in half-PPR scoring in 2024). It is best to avoid the 26-year-old, whether he stays the team's WR2 or gets promoted.

Najee Harris, RB, Los Angeles Chargers (Undervalued)

The Los Angeles Chargers signed Najee Harris to a one-year deal for the 2025 season. On top of Harris's absolute talent, this move makes the RB an undervalued prospect for dynasty leagues.

The former Pro Bowler produced four prolific seasons with the Steelers, rushing for over 1,000 yards yearly. He has been one of the more trustworthy runners in the league, playing in all 68 regular-season games since being drafted 24th overall in 2021.

Last season, even in a struggling Steelers offense, Harris posted 1,043 rushing yards on 263 touches with six scores. He can handle a high-volume workload when called upon.

Najee Harris remained a tough runner to bring down in 2024, forcing 70 missed tackles (12th-most in NFL).

Now, moving to Los Angeles, the running back sees a significant upgrade in his offensive environment and opportunity. Chargers head coach Jim Harbaugh is a big fan of establishing the run. The Chargers offensive line is a significant improvement over the Steelers' inconsistent unit.

In 2024, J.K. Dobbins thrived on this team, rushing for 905 yards and nine TDs on 195 totes. Harris is now the strong three-down option in a Justin Herbert-led offense. The former Steeler is a more talented back than Dobbins and should put up ample numbers in his first season with his new team.

Harris offers durability, production, and a high ceiling. His situation has improved, and so should his fantasy stats. Currently, RotoBaller has Harris ranked as the RB34 in dynasty rankings. While his long-term future is uncertain due to his one-year deal, his ability to produce in a better blocking offense should make him one of the best dynasty bargains.

Calvin Ridley, WR, Tennessee Titans (Undervalued)

An undervalued dynasty asset for the upcoming season is wide receiver Calvin Ridley, currently ranked WR50 on RotoBaller's dynasty rankings. He is coming off a 1,017-yard season with four touchdowns.

It did take time for Ridley to get going in 2024. He struggled with just 12 receptions on 36 targets for 183 yards and a touchdown over his first six contests. Ridley's role expanded significantly after DeAndre Hopkins was traded in October.

Wide receiver Treylon Burks tore his ACL during an October practice, and Nick Westbrook-Ikhine is now in Miami. The Titans have added Van Jefferson on a one-year deal, but he should not impact Ridley's role. The Alabama product is essentially the Titans' only proven playmaker at the WR position.

CALVIN RIDLEY!

Part of the reason Ridley finds himself ranked so low is that he is tied to the Titans offense. Will Levis is an unreliable quarterback, which limits Ridley's ceiling.

The Titans could draft a new quarterback with the No. 1 overall pick. If this happens, Ridley's value will rise. Even if Tennessee sticks with Levis, Ridley should continue to command a high target share.

At 30 years old, Ridley is at the point where some dynasty managers start fading receivers. His current ranking of WR50 seems too low for the team's top receiving option, and we should see his value increase as the season gets closer. He'll be a great stash, even in his less-than-ideal situation. If Levis (somehow) improves or the team selects a quarterback in the draft, Ridley's value will exceed expectations.
