Only George Kittle, Brock Bowers and Trey McBride had more Fantasy points, amongst tight ends, than Jonnu Smith last season. That came with him fighting Tyreek Hill and Jaylen Waddle for targets, but Smith has since been traded to Pittsburgh, which has caused a jolt in the 2025 Fantasy football rankings. D.K. Metcalf is the only pass catcher clearly ahead of Smith on the Steelers, so the latter may have received a boost with his 2025 Fantasy football projections. Smith changing teams has ramifications not just for him but also for the incumbent tight ends in Pittsburgh and those left behind in Miami.

Those pegging Pat Freirmuth as a possible 2025 Fantasy football sleeper may now have to reconsider with him taking a backseat in Pittsburgh's offense. Meanwhile, Miami signed veteran Darren Waller, who spent last season retired, to a one-year deal. Waller last played with the Giants in 2023 and finished with just one touchdown reception. Before crafting your 2025 Fantasy football draft strategy, be sure to check out the 2025 Fantasy football rankings and cheat sheets from the proven computer model at SportsLine.

Last year, the model accurately predicted that Bills running back James Cook would comfortably outperform his ADP (RB14). The result: Cook rushed for 1,009 yards and 16 touchdowns while adding 32 receptions for 258 yards and two more scores as a receiver. He finished as RB8 in CBS Sports PPR leagues and his maturation into a scoring threat cemented his status as a Fantasy football superstar.

The same model has a proven track record providing Fantasy football tips, identifying A.J. Brown as a sleeper in 2020, nailing Jonathan Taylor's monstrous season in 2021 and correctly predicting C.J. Stroud would take a step back in 2024. Additionally, it's called past Fantasy football sleepers like Derrick Henry in 2019, Christian McCaffrey and Alvin Kamara in 2018, and Davante Adams in 2017. Anybody who banked on players like those made a run at their league title.

The model is powered by the same people who generated projections for all three major Fantasy sites, and it beat human experts last season when there was a big difference in ranking. The 2025 Fantasy football PPR rankings and 2025 Fantasy football standard rankings update multiple times daily, so you're always getting the best Fantasy football advice.

Now, SportsLine has simulated the entire NFL season 10,000 times and released its latest Fantasy football rankings 2025, along with plenty of sleepers, breakouts and busts. Head to SportsLine now to see them. 

Top 2025 Fantasy football sleepers

One of the 2025 Fantasy football sleepers the model is predicting: Seahawks running back Kenneth Walker III, who has a rushing yardage over/under of 875.5 this season. He simply could not evade the injury bug in 2024, missing Weeks 2 and 3 due to an oblique, missing Weeks 14 and 15 due to a calf, and missing Weeks 17 and 18 due to an ankle. It was apparent that Walker was playing at less than full health as he averaged just 3.7 yards per carry after averaging 4.4 over his first two seasons. Even with that decrease in productivity and missing six games, he scored at least eight touchdowns for the third straight year.

Walker played 15 games in each of his first two seasons, so a return to good health can be expected, and Seattle appears to be moving towards a run-oriented offense. It moved on from vets Geno Smith, DK Metcalf and Tyler Lockett, while the Seahawks took an offensive guard with their first-round pick, and then were the only team to select a fullback in the 2025 NFL Draft. After dropping to the RB29 last season, SportsLine's advanced model has lofty Fantasy football projections for Walker in 2025 and has him as a top-20 Fantasy running back.

Another sleeper that SportsLine's Fantasy football rankings 2025 have identified: Titans receiver Calvin Ridley. Despite having arguably the worst quarterback situation in the NFL, Ridley posted a 1,000-yard receiving season in 2024, his second in a row. He really found his stride over the second half of the year as he was a top-15 Fantasy wideout from Weeks 8-18, outproducing A.J. Brown and Mike Evans. Top overall pick Cam Ward will now assume control in Tennessee, and the Titans have made a concerted effort in building chemistry between the rookie and Ridley, even placing their lockers next to each other.

Ridley's metrics check all of the boxes as he set career highs in yards per reception (15.9) and yards before catch per reception (12.3) last year. That ability to get downfield pairs perfectly with a strong-armed quarterback like Ward, and there are fewer mouths to feed in Tennessee with DeAndre Hopkins and Tyler Boyd no longer in town. The model likes Ridley as a Fantasy football sleeper and has him above the likes of Garrett Wilson and Jameson Williams in its 2025 Fantasy football rankings. See which other Fantasy football sleepers 2025 to pick here.

Brown and Drake London. You can only see who it is, and the 2025 Fantasy football rankings for every player, at SportsLine.
