Watch Now: Time to Schein: The Cowboys have a realistic chance to win a Super Bowl this year (2:53)

As you prepare for your last-minute drafts, running back has become the most difficult position to prepare for, with several teams employing a stable of backs with varying skill sets. In Los Angeles, the Rams have Malcolm Brown for early-down work, Cam Akers as a home-run hitter and Darrell Henderson as an all-around back. Meanwhile, Washington, Baltimore, Indianapolis, Jacksonville, Tampa Bay and Detroit all have complicated timeshares, but a reliable set of 2020 Fantasy football rankings is the best way to sort through it all.

Which 2020 Fantasy football sleepers at running back should you target? And which 2020 Fantasy football breakouts and busts are lurking in your player pool? Before going on the clock this season, be sure to see the latest Fantasy football rankings 2020 and cheat sheets from the team at SportsLine, given the success they've had in calling sleepers like Titans running back Derrick Henry

The team at SportsLine was all over Henry from the start in 2019. He was going off the board around the fifth round, but SportsLine had him ranked as a top-20 back and graded him higher than multiple running backs who were picked in the third round on average. The result: Henry finished as the 2019 rushing champion and as the No. 2 Fantasy running back. Fantasy players who followed SportsLine's advice got a season-defining steal. 

The same model has a proven track record providing Fantasy football tips, calling past sleepers like Christian McCaffrey and Alvin Kamara in 2018, as well as Davante Adams in 2017. Anybody who banked on players such as those likely made a run at their league title.

This same model is power by the same people who generated projections for all three major Fantasy companies, 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 2020 Fantasy football rankings, along with plenty of sleepers, breakouts and busts. Head to SportsLine now to see them

Top 2020 Fantasy football sleepers 

SportsLine's Fantasy football rankings 2020 and cheat sheets are all over Titans quarterback Ryan Tannehill. The Titans named Tannehill the starter in Week 7 last season, and the former Texas A&M standout proceeded to have a sensational season. Tannehill completed over 70 percent of his passes in 2019, finishing with 2,742 passing yards and 22 touchdowns against just six interceptions.

He averaged 9.6 yards per attempt, nearly two yards higher than his prior career-high, while his 7.7 percent touchdown rate was three points higher than his career average.

However, Fantasy football players have still been sleeping on Tannehill, waiting until the 14th round on average according to the latest 2020 Fantasy football ADP. The model says he'll outperform fellow quarterbacks like Cam Newton and Matthew Stafford, both of whom are coming off the board two rounds earlier on average.

Another sleeper that SportsLine's Fantasy football rankings 2020 have identified: Colts running back Marlon Mack. He will contend with rookie Jonathan Taylor for touches, but in an offseason with limited training camp news and no preseason games, veterans may have the upper hand.

Mack is already proven to be one of the most explosive runners in the game, with 29.7 percent of his 1,091 rushing yards coming on breakaway runs of 15 yards or more. With Taylor grinding on defenses, Mack's burst should shine even if his touch count is diminished. That's why the model ranks him ahead of sixth-round options like Devin Singletary and Leonard Fournette despite the fact that Mack is going in the eighth round on average.

How to find 2020 Fantasy football rankings 

SportsLine is also extremely high on an overlooked wide receiver going off in the middle rounds of 2020 Fantasy football drafts. This receiver is ranked in the top 10 at his position and in line to outperform receivers being taken much earlier like Mike Evans and Adam Thielen. You can only see who it is, and the 2020 Fantasy football rankings for every player, at SportsLine.
