Players like Justin Jefferson, Justin Herbert and James Robinson weren't on many radars entering the 2020 NFL season. All three, however, ended up being among the top Fantasy football sleepers. With the new NFL season just around the corner, the search is on for overlooked players who aren't high in the 2021 Fantasy football rankings, but are well-positioned to become 2021 Fantasy football sleepers and breakouts who can help bring championships.

Is Mike Davis a player to target during your 2021 Fantasy football draft prep as he takes over in the backfield for Atlanta? Could Jameis Winston or Taysom Hill be players to consider as part of your 2021 Fantasy football strategy as one of them takes over for Drew Brees in Sean Payton's high-flying offense? Before making any 2021 Fantasy football picks, be sure to check out the 2021 Fantasy football cheat sheets from the proven computer model at SportsLine.

Last year, the model accurately predicted a big season for Titans wide receiver A.J. Brown. The second-year playmaker had a fifth-round Fantasy football ADP, but the SportsLine Projection Model predicted he'd be a WR1. The result: Brown caught 70 passes for 1,075 yards and 11 touchdowns to finish as the No. 10 wide receiver in Fantasy football.

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 projections 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 2021, identifying several potential Fantasy football sleepers. Head to SportsLine now to see them

Top 2021 Fantasy football sleepers 

One of the 2021 Fantasy football sleepers the model is predicting: Ravens running back Gus Edwards. J.K. Dobbins is getting most of the attention in Baltimore's backfield, but Edwards is a sneaky pick who could steal touchdowns in that prolific offense after Mark Ingram departed in the offseason. Edwards has produced at least 700 rushing yards and a 5.0 yards-per-carry average over the past three years.

After scoring just four combined touchdowns in 2018 and 2019, he upped that number to six in 2020. If Dobbins were to go down, Edwards could be a steal, but even in his expected role, the 240-pounder could still be a valuable asset. Even though the 2021 Fantasy football ADP shows Edwards going off in the 11th round, he is projected to outperform players like James Conner (eighth-round ADP), Ronald Jones (10th) and Kenyan Drake (10th).

Another sleeper that SportsLine's Fantasy football rankings 2021 have identified: Dolphins running back Myles Gaskin. After playing sparingly as a rookie in 2019, Gaskin worked his way into Miami's backfield rotation in 2020 and eventually won the No. 1 role, rushing for 584 yards and three touchdowns while adding 41 receptions for 388 yards and two more scores despite playing in only 10 games.

In the last eight games that he played in 2020, he averaged 19.6 touches per game. Gaskin's receiving ability makes him a particularly strong value in PPR formats, as he ranked first among running backs in yards per catch (9.5) and third in yards per route run (2.08). That's a big reason why the model likes him over fifth-round options like David Montgomery and Josh Jacobs despite the fact that he has a sixth-round 2021 Fantasy football ADP.
