The NFL schedule expanded from 16 to 17 games this year, and a longer season means that nailing your 2021 Fantasy football draft prep is more critical than ever. Building a roster is a season-long process, but it starts by making sure you squeeze value from your 2021 Fantasy football picks. Owners who stayed up to speed on the Jaguars' depth chart last season were able to scoop up James Robinson in the late rounds, and the undrafted free agent helped lead thousands to championships.

This year, there are plenty of young, hungry players and veterans stepping into new roles that might help them dramatically exceed their 2021 Fantasy football ADP. A reliable set of 2021 Fantasy football rankings can help you identify the 2021 Fantasy football sleepers, breakouts and busts who will define the upcoming season and help you figure out where to target stars like Aaron Rodgers, Julio Jones and Lamar Jackson. Before setting your 2021 Fantasy football draft strategy, be sure to check out the 2021 Fantasy football cheat sheets from the proven computer model at SportsLine.

Last year, the model accurately predicted that Bills quarterback Josh Allen was being drastically undervalued. His Fantasy football ADP was barely in the top 70, but the model pegged him as a top-five Fantasy quarterback, a QB1 who would finish well ahead of players like Kyler Murray, Tom Brady and Drew Brees. Allen ended up being the No. 2-scoring Fantasy QB, outscoring all three of those other quarterbacks and even surpassing Patrick Mahomes. Fantasy players who followed SportsLine's advice reaped plenty of value with that pick. 

The same model has a proven track record providing Fantasy football tips, also identifying A.J. Brown as another sleeper in 2020 and players like Devin Singletary and JuJu Smith-Schuster as busts last season. 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, along with plenty of sleepers, breakouts and busts. Head to SportsLine now to see them

Top 2021 Fantasy football sleepers 

One of the 2021 Fantasy football sleepers the model is predicting: Falcons wide receiver Russell Gage. The former LSU star is coming off his best season yet, reaching career-highs in targets (109), receptions (72), receiving yards (786) and touchdowns (4). Now, he's poised to take on an even larger role in the Falcons' offense. Julio Jones was traded away during the offseason, making Gage the clear-cut No. 2 wide receiver behind Calvin Ridley.

Gage also has significant touchdown upside after finishing ninth among wide receivers in red-zone targets (17) last season. That's a big reason why the model ranks Gage, who has a 16th-round 2021 Fantasy football ADP, ahead of a 12th-round option like Michael Pittman Jr. and a 13th-round option like Mike Williams.

Top 2021 Fantasy football breakouts 

The model is also projecting Patriots running back Damien Harris as one of its top 2021 Fantasy Football breakouts. The third-year pro rushed for 691 yards on 137 carries and two touchdowns in 2020 despite playing in just 10 games. Harris missed time in 2020 due to back and ankle injuries.

Despite his abbreviated sophomore campaign, Harris clearly seized the RB1 spot in New England away from Sony Michel. The former Alabama standout has a strong chance to get close to a 1,000-yard season in 2021 if he can remain healthy, as his 5.0 yards-per-carry average is a respectable clip. SportsLine's 2021 Fantasy football running back rankings agree, listing Harris ahead of backs like Javonte Williams, Michael Carter and Trey Sermon.

Top 2021 Fantasy football busts

As for players to avoid, the model lists Eagles tight end Dallas Goedert as one of its top 2021 Fantasy football busts. The former South Dakota State product caught 46 passes for 524 yards and three touchdowns in 2020. He missed five games with a small fracture in his ankle.

Splitting time is never optimal for a tight end, and the Eagles still have veteran Zach Ertz for his ninth season in the City of Brotherly Love. Ertz could be destined for a trade before the NFL season officially begins, but if he remains in Eagles green, it will spell greatly reduced reps for Goedert. SportsLine's model ranks Goedert below tight ends like Jared Cook, Robert Tonyan and Tyler Higbee.
