The NFL Week 1 schedule is here, and it's full of intriguing matchups to finalize your 2021 Fantasy football rankings. One of those: Tua Tagovailoa and Mac Jones face off in a battle of former Alabama quarterbacks when the Patriots play the Dolphins. With Tagovailoa the starter in Miami and Jones winning the job in New England, both players could factor into your 2021 Fantasy football strategy, but how do you know who to pick? That's where a reliable list of 2021 Fantasy football sleepers will come in handy.

Tagovailoa vs. Jones is hardly the only interesting quarterback matchup Week 1 has to offer from a Fantasy football rankings 2021 perspective, but it is unique. It's also a spot where casual and hardcore fans alike may have trouble deciphering the long-term implications. 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: Bears quarterback Justin Fields. Chicago made him the fourth quarterback taken in the first round and he has a chance to outperform vets who have started for years. Fields is expected to take over as Chicago's starter sooner than later, and as a dual-threat QB, he could yield a big return for fantasy owners.

Fields completed 61 percent of his passes and rushed for 92 yards during the preseason. His 8.4 yards per carry were third-highest among all NFL players with ten or more attempts. Fields' most recent 2021 Fantasy football ADP is behind Jalen Hurts, Matthew Stafford and Matt Ryan, all of whom are predicted to have lower Fantasy value than Fields.

Another sleeper that SportsLine's Fantasy football rankings 2021 have identified: Ravens running back Ty'Son Williams. The little-known back has seen his potential role increase with starter J.K. Dobbins lost for the season, and SportsLine's model likes the odds he takes advantage. Williams didn't get a carry in 2020 during his first NFL season, but he's climbing the depth chart in Baltimore at the right time.

Fantasy owners are selecting Williams in the 13th round on average in 12-team leagues. That provides plenty of value for owners scouring the internet for potential sleepers. The players who SportsLine projects to perform similarly, like Ronald Jones and Kenyan Drake, are off the board in the ninth or 10th round.
